Find the Circumference and area of the circle with the center C=(-1, 6) and a point on the circle A(3, 9). Round to the nearest tenth

Answers

Answer 1

Circumference of circle is 31.4 and area of circle is 78.6

Given, C(-1,6) is center and A(3, 9) is a point on circle.

CA is the radius of the circle.

Using Distance Formula

[tex]r=\sqrt{(3-(-1))^2+(9-6)^2}[/tex]

[tex]r=\sqrt{(4)^2+(3)^2}[/tex]

[tex]r=\sqrt{16+9}[/tex]

[tex]r=\sqrt{25}=5[/tex]

We know the the formula for circumference of circle C = 2πr

C = 2*22/7*5

= 31.428

Rounding to nearest tenth

C = 31.4

Area of the circle = [tex]\pi r^2[/tex]

[tex]A=\frac{22}{7}(5)^2[/tex]

= 78.571

Rounding to nearest tenth

A = 78.6

Hence, circumference of circle is 31.4 and area of circle is 78.6.

Sam puts a cash deposit of $8,000 on a used car. the bank is charging sam an interest rate of 4.75% per year. how much interest will he pay to the bank at the end of 5 years?

Answers

At the end of 5 years, Sam will have paid $1,900 in interest to the bank. This calculation assumes that the interest rate remains constant and is applied on a simple basis, rather than being compounded over the 5-year period.

Sam makes a cash deposit of $8,000 on a used car and is charged an interest rate of 4.75% per year by the bank. To calculate the interest he will pay at the end of 5 years, we can use the formula for simple interest, which is I = P × R × T, where I is the interest, P is the principal (the initial deposit), R is the interest rate, and T is the time in years.

In this case, P = $8,000, R = 4.75% (or 0.0475 in decimal form), and T = 5 years. Plugging these values into the formula, we get:

I = $8,000 × 0.0475 × 5

I = $1,900

Sam will pay $1,900 in interest to the bank at the end of 5 years.

How to find interest rate?

The interest rate is 4.75% per year, which can be written as 0.0475 as a decimal. The amount of interest that Sam will pay after 5 years can be calculated using the simple interest formula:

Interest = Principal x Rate x Time

where Principal is the initial deposit, Rate is the interest rate, and Time is the length of time the interest is charged for.

In this case, the Principal is $8,000, the Rate is 0.0475, and the Time is 5 years. Plugging these values into the formula, we get:

Interest = $8,000 x 0.0475 x 5

Interest = $1,900

Therefore, Sam will pay $1,900 in interest to the bank at the end of 5 years.

Find the area of triangle ABC given that AB= 8cm , AC = 6cm , ∠ = 55° ∠ = 35°.

a) 48cm*2 b) 12cm*2 c) 24cm*2 d) 5cm*2

Answers

It seems that you're missing some angle labels. I'll assume ∠A = 55° and ∠B = 35°. To find the area of triangle ABC, we can use the formula:

Area = (1/2) * a * b * sin(C)

where a and b are the side lengths, and C is the angle between them. In our case, a = 8 cm, b = 6 cm, and ∠C = 180° - (∠A + ∠B) = 180° - (55° + 35°) = 90°.

Now, we can plug in the values:

Area = (1/2) * 8 cm * 6 cm * sin(90°)

Since sin(90°) = 1, the area becomes:

Area = (1/2) * 8 cm * 6 cm = 24 cm²

So, the correct answer is c) 24 cm².

Step-by-step explanation:

so like you use sine rule to find line BC and i got 7.3 the you have to split the triangle in half to get a right angle triangle then divide 7.3 by two to get 3.7 and then use .pythagoras theorem to find the height and then use the area of a triangle formula to get your answer as option (C)

Which of the following is a typical characteristic of debit cards? (1 point)
O Your bank may charge you a very large fee each time you use one.
O When you buy something from a store, you may be offered a discount if you open one with the store.
O They usually charge a lower interest rate than credit cards.
They are tied directly to your bank account.

Answers

A typical characteristic of debit cards is expressed by option D, they are tied directly to your bank account, since money has to be deducted for a purchase to be made.

How debit cards function

When you use a debit card to make a purchase, the money is deducted directly from your bank account. Debit cards do not typically charge interest like credit cards do, so C is not correct.

A is also not correct since most banks do not charge a fee for using a debit card, although some may charge fees for using an out-of-network ATM or overdraft fees if you spend more than you have in your account. B is not a typical characteristic of debit cards either, as there is generally no connection between a store's loyalty program or discounts and using a debit card for payment.

Therefore, it is possible to conclude that debit cards have option D as their characteristic. Since they require money in the bank to make the purchase, they are connected to one's account.

Last season joao scored a goal in 3/5 or 60% of the soccer games. use this experimental probability to determine the number of games he will score a goal this season, if he plays in 10 games

Answers

If Joao scored a goal in 60% of the soccer games last season, then we can expect him to score a goal in about 60% of the games he plays this season.

So, if Joao plays in 10 games this season, we can estimate that he will score a goal in approximately 60% of those games.

To calculate the actual number of games he is expected to score a goal in, we can use the formula:

Expected number of goals = Total number of games x Probability of scoring a goal

Plugging in the numbers, we get:

Expected number of goals = 10 x 0.6 = 6

Therefore, based on the experimental probability from last season, we can estimate that Joao will score a goal in around 6 games out of the 10 he plays this season.

Consider a roulette wheel. Roulette wheel has 2 green slots, 18 red slots, and 18 black slots. The wheel is spun and we are interested in the number of spins before the Rth success. : Let success be landing in a green slot. Find the following probabilities. A) identity the distribution with the parameters B) the 8th success occurs on the 17th spin. C) the 13th success occurs between the 31st and the 34th spin. PLEASE SOMEONE HELP <3

Answers

A) The distribution is a negative binomial distribution with parameters r and p.

B) The probability that the 8th success occurs on the 17th spin is approximately 0.8%.

C) The probability that the 13th success occurs between the 31st and 34th spin is approximately 0.6%.

A) The distribution is a negative binomial distribution with parameters r = number of successes (in this case, r = 1 since we are only interested in the first success), and p = probability of success (landing in a green slot).

B) To find the probability that the 8th success occurs on the 17th spin, we use the formula for the negative binomial distribution:

P(X = k) = (k-1)C(r-1) * [tex]p^r[/tex] * [tex](1-p)^{(k-r)[/tex]

where X is the number of spins until the Rth success, k is the number of spins, and C(n,r) is the binomial coefficient (n choose r).

In this case, we want to find P(X = 17) when r = 8 and p = 2/38 (since there are 2 green slots out of 38 total slots):

P(X = 17) = (16 C 7) * (2/38)⁸ * (36/38)⁹
          ≈ 0.008 or 0.8%

So the probability that the 8th success occurs on the 17th spin is approximately 0.8%.

C) To find the probability that the 13th success occurs between the 31st and 34th spin, we need to find the probability of getting exactly 12 successes in the first 30 spins, followed by a success on one of the next 4 spins (31st, 32nd, 33rd, or 34th).

P(31 ≤ X ≤ 34) = P(X ≤ 34) - P(X ≤ 30)
               = ∑[k=13 to 34] (k-1 C 12-1) * (2/38)¹² * [tex](36/38)^{(k-12)[/tex] - ∑[k=1 to 30] (k-1 C 12-1) * (2/38)¹² * [tex](36/38)^{(k-12)[/tex]
               ≈ 0.006 or 0.6%

So the probability that the 13th success occurs between the 31st and 34th spin is approximately 0.6%.

The Volume and the surface area of the given figure are 87 in³ and 83 in²  

To find the volume of the figure, we need to split it into smaller rectangular parts and find the volume of each part separately. From the given measurements, we can see that the figure consists of three rectangular parts:

The volume of each part can be found using the formula:

Volume = length x width x height

Part 1: A rectangular prism with dimensions 3 in x 3 in x 1 in

Volume = 3 in x 3 in x 1 in

Volume = 9 in³

Part 2: A rectangular prism with dimensions 1 in x 6 in x 7 in

Volume = 1 in x 6 in x 7 in

Volume = 42 in³

Part 3: A rectangular prism with dimensions 6 in x 6 in x 1 in

Volume = 6 in x 6 in x 1 in

Volume = 36 in³

Total Volume:

The total volume of the piecewise rectangular figure is the sum of the volumes of each part:

Total Volume = Volume of Part 1 + Volume of Part 2 + Volume of Part 3

= 9 in³ + 42 in³ + 36 in³

= 87 in³

To find the surface area of the figure, we need to find the area of each face and add them up. The figure has 6 rectangular faces, and the area of each face can be found using the formula:

Area = length x width

Part 1:

Top and Bottom faces:

Area = 3 in x 3 in

Area = 9 in²

Side faces:

Area = 3 in x 1 in

Area = 3 in² (x2)

Total Area of Part 1:

Total Area = 9 in² + (3 in² x 2)

= 15 in²

Part 2:

Top and Bottom faces:

Area = 1 in x 6 in

Area = 6 in²

Side faces:

Area = 1 in x 7 in

Area = 7 in² (x2)

Total Area of Part 2:

Total Area = 6 in² + (7 in² x 2)

= 20 in²

Part 3:

Top and Bottom faces:

Area = 6 in x 6 in

Area = 36 in²

Side faces:

Area = 6 in x 1 in

Area = 6 in² (x2)

Total Area of Part 3:

Total Area = 36 in² + (6 in² x 2)

= 48 in²

Total Surface Area:

The total surface area of the figure is the sum of the areas of all its faces:

Total Surface Area = Total Area of Part 1 + Total Area of Part 2 + Total Area of Part 3

= 15 in² + 20 in² + 48 in²

The farmer has a maximum of $7400 available for and cultivation. Each acre of Crop Arequires 20 labor hours, and each acre of Crop Brequires 25 tabor hours. The farmer has a maximum of 3400 labor hours available. If she expects to make a profit of $160/acre on Crop Aand $220/acre on Crop B, how many acres of each crop, and respectively should she plant to maximize her profit in dollars?

Answers

The farmer should plant 116 acres of Crop A and 104 acres of Crop B to maximize her profit, which would be $41,840.

To maximize profit, the farmer should plant the crop with the higher profit per acre until she runs out of money or labor hours.

Let x be the number of acres of Crop A to be planted, and y be the number of acres of Crop B to be planted.

The objective function (profit) is: Profit = 160x + 220y

The constraints are: Cost constraint: 30x + 560y ≤ 7400 Labor hour constraint: 20x + 25y ≤ 3400

To solve this problem using linear programming, we can use a graphing calculator or software.

However, we can also solve it manually by finding the corner points of the feasible region (the area that satisfies all constraints) and evaluating the objective function at each point. The corner points are: (0, 296/5) (116, 104) (170, 56) (222/5, 0)

Evaluating the objective function at each point, we get: (0, 296/5):

Profit = 0 + 160(296/5) = 9472 (116, 104):

Profit = 160(116) + 220(104) = 41840 (170, 56):

Profit = 160(170) + 220(56) = 38480 (222/5, 0):

Profit = 160(222/5) + 0 = 7104

Therefore, the farmer should plant 116 acres of Crop A and 104 acres of Crop B to maximize her profit, which would be $41,840.

Mrs. Kwon used 107/8 yards of the total fabric length for Sun's and Jin's costume.

Firstly we will convert the mixed fraction to fraction. The length of fabric of Sun's costume = ((5×2)+1)/2

Length of fabric of Sun's costume = 11/2 yards

The length of fabric of Jin's costume = ((8×7)+7)/8

Length of fabric of Jin's costume = 63/8 yards

Total length of fabric used = Length of fabric of Sun's costume + Length of fabric of Jin's costume

Total length of fabric used = 11/2 + 63/8

Taking LCM we get-

Total length of fabric used = (11×4)+63/8

In nop, the measure of zp=90°, the measure of zn=39, and pn = 72 feet. find the length of op to the nearest tenth of a foot?​

Answers

The length of OP to the nearest tenth of a foot is approximately 41.5 feet

To find the length of OP, we can use the Pythagorean theorem since we have a right triangle.

OP^2 = PN^2 - ON^2

First, we need to find ON using the trigonometric ratio of tangent.

tan(39) = ON/PN

ON = PN * tan(39)
ON = 72 * tan(39)
ON ≈ 53.4 feet

Now we can plug in our values:

OP^2 = 72^2 - 53.4^2
OP^2 ≈ 1720.84
OP ≈ 41.5 feet (rounded to the nearest tenth of a foot)

Therefore, the length of OP to the nearest tenth of a foot is approximately 41.5 feet.

The values of given conditions are:

1. median=70

2. Lower quartile=40

3. Upper quartile=87

4. Range=170

5. IQR=47

6. Lower outlier threshold=-20.5

7. Upper outlier threshold=160.5

What is median?

In statistics, the median is the value separating the higher half from the lower half of a dataset. In other words, it is the middle value of a dataset when it is ordered in ascending or descending order.

Here,

To find the median time, we need to arrange the data in order from least to greatest and find the middle value.

10, 15, 30, 35, 40, 40, 45, 55, 60, 62, 64, 64, 66, 68, 70, 70, 72, 75, 75, 80, 82, 84, 90, 90, 105, 110, 120, 180

There are 28 values in the data set, so the median is the average of the 14th and 15th values:

Median = (70 + 70)/2

= 70

To find the lower quartile, we need to find the median of the lower half of the data set:

10, 15, 30, 35, 40, 40, 45, 55, 60, 62, 64, 64, 66, 68

There are 14 values in the lower half, so the lower quartile is the median of these values:

Lower quartile = (40 + 40)/2

= 40

To find the upper quartile, we need to find the median of the upper half of the data set:

72, 75, 75, 80, 82, 84, 90, 90, 105, 110, 120, 180

There are 14 values in the upper half, so the upper quartile is the median of these values:

Upper quartile = (84 + 90)/2

= 87

To find the range, we subtract the smallest value from the largest value:

Range = 180 - 10

= 170

To determine if there are any outliers in the data set, we need to calculate the interquartile range (IQR):

IQR = Upper quartile - Lower quartile

= 87 - 40

= 47

Any value that is more than 1.5 times the IQR below the lower quartile or above the upper quartile is considered an outlier.

Lower outlier threshold = Lower quartile - 1.5IQR

= 40 - 1.547

= -20.5

Upper outlier threshold = Upper quartile + 1.5IQR

= 87 + 1.547

= 160.5

To draw a box-and-whisker plot, we need to plot a box from the lower quartile to the upper quartile, with a line inside the box representing the median. We then draw whiskers extending from the box to the smallest and largest values that are not outliers. The box extends from 40 to 87, with a line at 70 representing the median. The whisker on the left extends to the smallest non-outlier value of 10, and the whisker on the right extends to the largest non-outlier value of 120.

Dorothy made a dot plot showing the heights of her plants in her garden. write a proportion to find the percentage of plants that are exactly 13cm tall.

2/9 = x/100

13/100 = x/100

2/12 = x/100

2/13 = x/20
right answer please.

Answers

To find the percentage of plants that are exactly 13cm tall using a proportion, you need to first identify the number of plants that are 13cm tall and the total number of plants. Based on your question, let's assume that 2 out of 9 plants are exactly 13cm tall.

Now, set up a proportion with the given information:

(number of plants 13cm tall) / (total number of plants) = (x) / (100)

In this case, the proportion is:
2/9 = x/100

To solve for x, cross-multiply:
2 * 100 = 9 * x
200 = 9x

Now, divide both sides by 9:
x = 200 / 9
x ≈ 22.22
So, approximately 22.22% of the plants in Dorothy's garden are exactly 13cm tall.

9. The value of a book is $258 and decreases at a rate of 8% per year. Find the value of the book after 11 years.


2 S5698


h $159. 05


c. $101. 38


d. S103. 11

Answers

The value of the book after 11 years is $101.38. Therefore, the correct option is C.

Find the value of the book after 11 years with an initial value of $258 and a decrease rate of 8% per year as follows.

1. Convert the percentage decrease to a decimal by dividing it by 100:

8% / 100 = 0.08

2. Subtract the decimal from 1 to represent the remaining value each year:

1 - 0.08 = 0.92

3. Raise the remaining value (0.92) to the power of the number of years (11):

0.92^11 ≈ 0.39197

4. Multiply the initial value of the book ($258) by the calculated remaining value (0.39197):

$258 × 0.39197 ≈ $101.07

Therefore, after 11 years, the value of the book is approximately $101.07, which is closest to option C, $101.38.

Answers

To verify that F is a conservative vector field, we need to check if its curl is zero.

First, let's find the curl of F:

curl F = (∂Q/∂x - ∂P/∂y)k

where P = xy^2 + 1 and Q = x^2y - 2y

∂Q/∂x = 2xy and ∂P/∂y = 2xy

So,

curl F = (2xy - 2xy)k = 0

Since the curl is zero, we can conclude that F is a conservative vector field.

To find a function f such that F = ∇f, we need to integrate the components of F with respect to their respective variables:

∂f/∂x = xy^2 + 1

f = (1/2)x^2y^2 + x + g(y)

Taking the partial derivative of f with respect to y, we get:

∂f/∂y = x^2 + g'(y) = x^2y - 2y

Integrating this with respect to y, we get:

g(y) = -y^2

So,

f = (1/2)x^2y^2 + x - y^2

Therefore,

F = ∇f = (∂f/∂x)i + (∂f/∂y)j

= (xy^2 + 1)i + (x^2y - 2y)j

Finally, using the conservative property of F, we can use the line integral to find the work done by F along the given curve C:

W = ∫C F · dr

= ∫C (∂f/∂x)dx + (∂f/∂y)dy

= f(r(ostsi)) - f(r(0))

= (1/2)(ostsi)^2(ostsi)^2 + ostsi - (ostsi)^2 - (-1)

= 1/2(ostsi)^4 + ostsi + 1

The function f is any. Express D as a type II region. Express
D as a type I region and draw D.

Answers

According to the given function, D is a type I region that can be expressed as D = {(x,y) | 0 ≤ y ≤ f(x), 2y ≤ x ≤ 2}.

Consider the given double integral ∫∫f(x, y) dA= ∫⁴₀∫²ₓ f(x, y) dx dy, where f is any function. Here, we need to express the region D as a type II region and then as a type I region.

A type II region is a region in the xy-plane that is bounded above and below by two curves and bounded on the left and right by two vertical lines. In other words, a type II region is a region that can be expressed as D = {(x,y) | a ≤ x ≤ b, g(x) ≤ y ≤ h(x)}, where a, b, g(x), and h(x) are functions.

To express D as a type II region, we first note that the given integral has the limits of integration as ∫⁴₀ and ∫²ₓ, which implies that the region D is bounded on the left by the y-axis and on the bottom by the x-axis. Also, the region D is bounded on the right by the vertical line x = 2x, and on the top by the curve y = f(x).

Therefore, we can express D as D = {(x,y) | 0 ≤ x ≤ 2, 0 ≤ y ≤ f(x)}, which is of the form D = {(x,y) | a ≤ x ≤ b, g(x) ≤ y ≤ h(x)}. Hence, D is a type II region.

Next, we need to express D as a type I region. A type I region is a region in the xy-plane that is bounded on the left and right by two curves and bounded above and below by two horizontal lines. In other words, a type I region is a region that can be expressed as D = {(x,y) | c ≤ y ≤ d, p(y) ≤ x ≤ q(y)}, where c, d, p(y), and q(y) are functions.

To express D as a type I region, we need to find the equations of the curves that bound the region D. From the given integral, we know that the region D is bounded on the left by the y-axis and on the bottom by the curve y = 0. Also, the region D is bounded on the top by the curve y = f(x) and on the right by the vertical line x = 2.

Therefore, we can express D as D = {(x,y) | 0 ≤ y ≤ f(x), x/2 ≤ y}, which can be rewritten as D = {(x,y) | 0 ≤ y ≤ f(x), 2y ≤ x ≤ 2}, where 2y ≤ x ≤ 2 corresponds to the line x = 2y.
