Answers

The trignometric equation h = (32 inches) x tan(35°) can be used to solve for the height, h, of the television screen.

We can use trigonometry to solve for the height, h, of the television screen. From the given information, we can form a right triangle with the diagonal of the television screen as the hypotenuse, and the height of the screen as one of the legs.

Since we are given the angle between the diagonal and the bottom of the television, we can use the trigonometric function tangent to relate the height and the diagonal.

The equation we can use to solve for the height is:

tan(35°) = [tex]\frac{h }{ (32 inches)}[/tex]

Rearranging this equation, we get:

h = (32 inches) x tan(35°)

Therefore, the equation that can be used to solve for the height, h, of the television screen is:

h = (32 inches) x tan(35°)

If a person takes 125 milligrams of a drug, whose concentration
decreases by 30% each hour. how long will it take for the concentration of
the drug in the bloodstream to be 1 milligram?

Answers

It takes approximately 10 hours for the drug concentration to decrease.

What is the quadratic formula?

We can use exponential decay to model the concentration of the drug in the bloodstream. Let C(t) be the concentration of the drug in milligrams at time t in hours since the person took the drug. Then we have:

[tex]C(t) = 125(0.7)^t[/tex]

where 0.7 is the factor by which the concentration decreases each hour.

We want to find the time t such that C(t) = 1. Substituting this into the equation above, we get:

[tex]1 = 125(0.7)^t[/tex]

Dividing both sides by 125, we get:

[tex]0.008 = (0.7)^t[/tex]

Taking the logarithm of both sides with base 0.7, we get:

[tex]t = log(0.008) / log(0.7)[/tex]

Using a calculator, we can evaluate this expression to get:

t ≈ 10.07

Therefore, it will take approximately 10.07 hours for the concentration of the drug in the bloodstream to be 1 milligram.

Answers

The road with alternating white and black stripes and each 50 cm wide is 7.5 m wide.

The road consists of alternating white and black stripes

No. of white stripes = 8

As the first and last stripe is white so in between the black stripes will be 7

No. of black stripes = 7

Total no. of stripes = 15

Width of black stripe = 50 cm

Width of white stripe = 50 cm

Width of whole road = total no. of stripes × width of each stripe

Width of whole road = 15 × 50

Width of whole road = 750 cm

To convert m into cm

Now, 1 m = 100 cm

1 cm = 1/100 m

750 cm = 750/100 m

2. A manufacturer of electronic kits has found that the mean time required for novices to assemble its new circuit tester is 3. 15 hours, with a sample standard deviation of 0. 23 hours. A consultant has developed a new instructional booklet intended to reduce the time an inexperienced kit builder will need to assemble the device. In a test of the effectiveness of the new booklet, 25 novices require a mean of 2. 98 hours to complete the job. Assuming the population of times is normally distributed, and using the 0. 01 level of significance, should we conclude that the new booklet is effective? Determine and interpret the p-value for the test

Answers

Assuming the population of times is normally distributed, and using the 0. 01 level of significance, we can conclude that the new booklet is effective.

To determine if the new instructional booklet is effective in reducing the assembly time for novices, we will perform a one-sample t-test using the given information.

1. State the null hypothesis (H0) and the alternative hypothesis (H1):

H0: There is no difference in the mean assembly time with the new booklet (µ = 3.15 hours).

H1: The mean assembly time with the new booklet is less than 3.15 hours (µ < 3.15 hours).

2. Identify the level of significance, sample size, sample mean, and sample standard deviation:

α = 0.01

n = 25

x = 2.98 hours

s = 0.23 hours

3. Calculate the test statistic:

t = (x - µ) / (s / √n) = (2.98 - 3.15) / (0.23 / √25) = -0.17 / 0.046 = -3.70

4. Find the p-value for the test:

Using a t-distribution table or calculator, the p-value for a one-tailed test with t = -3.70 and degrees of freedom (df) = 24 is approximately 0.0005.

5. Compare the p-value with the level of significance:

Since the p-value (0.0005) is less than α (0.01), we reject the null hypothesis.

Based on the p-value, we have enough evidence to conclude that the new instructional booklet is effective in reducing the assembly time for novices at the 0.01 level of significance.

Carl takes out a loan which accrues interest at a flat rate of 1.96% per quarter.
what is the equivalent yearly simple interest rate?

Answers

Carl will be charged 7.84% of the initial loan amount as interest.

When taking out a loan, it's important to understand the interest rate and how it will affect the total amount you will owe. In this case, Carl's loan accrues interest at a flat rate of 1.96% per quarter. This means that every quarter, Carl will be charged 1.96% of the initial loan amount as interest.

To determine the equivalent yearly simple interest rate, we use the formula: Yearly interest rate = Quarterly interest rate x 4. This formula works because there are four quarters in a year, so we can multiply the quarterly interest rate by four to get the annual interest rate.

In this case, the quarterly interest rate is 1.96%. Multiplying this by four, we get an annual interest rate of 7.84%. This means that over the course of a year, Carl will be charged 7.84% of the initial loan amount as interest.

Understanding the interest rate is important because it can significantly impact the total amount that you will owe on a loan. A higher interest rate means that you will pay more in interest over the life of the loan, which can make the loan more expensive overall.

By calculating the equivalent yearly simple interest rate, Carl can better understand how much he will owe in interest over the course of the loan and make an informed decision about whether or not to take out the loan.

Angad adds 20 to it, then doubles it and gets an answer of 53. what was the original number?

Answers

The original number was 17 to which when Angad adds 20, then doubles it and gets an answer of 53.

To solve this problem, we need to work backwards from the final answer. If Angad added 20 to the original number, we can subtract 20 from 53 to get 33. This means that after Angad doubled the number, he had 33.

To find the original number, we need to undo the doubling process. If Angad had 33 after doubling the number, we can divide 33 by 2 to get the original number.

33 divided by 2 equals 16.5. However, we know that the original number must be a whole number since we cannot add 20 to a decimal. Therefore, we can round up to the nearest whole number to get 17.

So, the original number was 17.

In summary, to find the original number, we worked backwards from the final answer and undid the steps that Angad took. We subtracted 20 to undo the addition, then divided by 2 to undo the doubling. We rounded up to the nearest whole number since the original number must be a whole number.

Answers

A. Kiran will be billed approximately $2,284.33 one year after the date of purchase if she does not make any payments.

B. In this case, the overall cost of the sofa would be approximately $2,284.08

How to solve the problems

To find the initial value of the home when Zahir purchased it, we can use the compound interest formula:

Future Value = Initial Value * (1 + (interest rate))^years

Let Initial Value be P. We are given the Future Value as $548,900, the interest rate as 4.8%, and the number of years as 15.

548,900 = P * (1 + 0.048)^15

Now, we'll solve for P:

P = 548,900 / (1 + 0.048)^15

P ≈ 305,113.48

a. Future Value = Initial Value * (1 + (interest rate / number of periods))^(years * number of periods)

Initial Value = $1,791.99

Interest Rate = 27.93% (0.2793)

Number of periods = 12 (monthly)

Years = 1

Future Value = 1,791.99 * (1 + (0.2793 / 12))^(1 * 12)

Future Value ≈ 2284.33

Kiran will be billed approximately $2,284.33 one year after the date of purchase if she does not make any payments.

b.  interest were compounded annually:

Future Value = Initial Value * (1 + interest rate)^years

Future Value = 1,791.99 * (1 + 0.2793)^1

Future Value ≈ 2284.08

Part B: If GA = 29 and a major arc mDUG = 185°, then determine the minor arc length of


GD.

Answers

The length of the minor arc GD is approximately 0.196π units.

To get the length of the minor arc GD, we need to subtract the measure of the major arc mDUG from the circumference of the circle, and then divide by 360° to find the length of one degree of arc.
First, we need to find the circumference of the circle. Since GA = 29, we know that the radius of the circle is also 29. The formula for the circumference of a circle is C = 2πr, so for this circle we have: C = 2π(29) = 58π
Next, we need to subtract the measure of the major arc mDUG from the circumference of the circle. Since mDUG = 185°, we have:
58π - (185/360)(58π) = (175/360)(58π)
Simplifying this expression, we get: (175/360)(58π) = 29(175/72)π ≈ 70.48π
Finally, we divide this value by 360° to find the length of one degree of arc:
(70.48π)/360 ≈ 0.196π
Therefore, the length of the minor arc GD is approximately 0.196π units.

In mathematics, a graph is a visual representation of a mathematical relationship. The equation y=1/2x ​is a linear equation, which means that it describes a straight line. This equation can be graphed using the number graph.

To graph the equation y=1/2x, one must first plot points on the graph. To do this, one can use the given equation to calculate the x and y values of the points. For example, if x is equal to 1, then y is equal to 1/2. Therefore, the point (1, 1/2) can be plotted on the graph. This process can be repeated for other values of x, such as 2, 3, and 4. The result is a straight line that passes through the points (1, 1/2), (2, 1), (3, 1 1/2), and (4,2).

The equation y=1/2x can also be graphed using the slope-intercept form of the equation. This form of the equation is written as y=mx + b, where m is the slope of the line and b is the y-intercept. For the equation y=1/2x, the slope is 1/2 and the y-intercept is 0. To graph the line, one must first plot the y-intercept, which is the point (0,0). Then, one must calculate the slope and draw a line through (0,0) in the direction of the slope. The result is a straight line that passes through the points (0, 0), (1, 1/2), (2,1), (3, 1 1/2), and (4, 2).

In conclusion, the equation y=1/2x can be graphed using either number graph or the slope-intercept form. In either case, the result is a straight line that passes through the same points.

Answers

The expression to show the total volume of the two boxes is:

100 + [tex]s^3[/tex] ([tex]in^3[/tex])

We can start by finding the volume of the smaller box using the formula for the volume of a cube:

Volume of smaller box = (length of one side)^3 = 100 in^3

Taking the cube root of both sides, we get:

Length of one side = ∛100 in ≈ 4.64 in

Now, we can use this value to find the volume of the larger box:

Volume of larger box = (length of one side)[tex]^3 = s^3[/tex]

The total volume of both boxes is the sum of the volume of the smaller box and the volume of the larger box:

Total volume = Volume of smaller box + Volume of larger box

Total volume = 100 in [tex]^3 + s^3[/tex]

Therefore, the expression to show the total volume of the two boxes is:

Find the area of a triangle that has sides of 7, 9, and 12 inches

Answers

The area of the triangle is approximately 31.3049 square inches.

The area of a triangle can be found using the formula: A = (1/2)bh, where b is the length of the base of the triangle, and h is the height (or perpendicular distance from the base to the opposite vertex).

However, in this case, we don't have the height. Instead, we can use

Heron's formula, which only requires the lengths of the three sides of the triangle:

A = √[s(s-a)(s-b)(s-c)],

where a, b, and c are the lengths of the sides of the triangle, and s is the semiperimeter (half the perimeter):  s = (a + b + c)/2.

Using the given values, we have:

s = (7 + 9 + 12)/2 = 14

A = √[14(14-7)(14-9)(14-12)]

A = √[14(7)(5)(2)]

A = √(980)

A ≈ 31.3049 square inches

SPEEDBOAT RACE Speedboats race around four buoys in the lake on a rectangular course. If the total length of the course is 2.4
kilometers and the ratio of the length to the width is 2:1, what are the length and width of the course?
length:
width:

Answers

Let's represent the width of the rectangular course as $w$. Then the length of the rectangular course can be represented as $2w$, since the ratio of the length to the width is given as 2:1.

We know that the total length of the course is 2.4 kilometers, so we can write an equation:

$\sf\implies\:2w + 2(2w) = 2.4$

Simplifying the equation:

$\sf\implies\:6w = 2.4$

$\sf\implies\:w = \frac{2.4}{6}$

$\bigstar\implies\sf{\textbf{\boxed{w = 0.4}}}$

Therefore, the width of the course is 0.4 kilometers.

The length of the course is $\sf\:2w = 2(0.4)=$

${\boxed{\sf{0.8 kilometers.}}}$

Hence, the length of the course is 0.8 kilometers and the width of the course is 0.4 kilometers.

Answers

The equation of the tangent plane to the surface at the point (u,v) = (3,U) is z = x + 34 + U.

To calculate TT, we need to find the partial derivatives of O(u,v) with respect to u and v:

TT = (∂O/∂u) x (∂O/∂v)
  = (2, 0, 8) x (0, 0, 1)
  = (-8, 0, 0)

To find n(u,v), we normalize TT:

n(u,v) = TT/|TT|
      = (-1, 0, 0)

At the point u=3, v=U, O(u,v) = (2u + 0.0 - 40, 8u) = (-34, 24).

To find the equation of the tangent plane, we first find the normal vector to the plane, which is n(u,v) = (-1, 0, 0). Then we use the point-normal form of the equation of a plane:

(-1)(x + 34) + 0(y - 24) + 0(z - U) = 0
-x - 34 + z - U = 0
z = x + 34 + U

A cylinder has a radius of 2 ft and a hight of 6 ft. What is the total surface area using 3.14 as pi.

Answers

The total surface area of a cylinder is the sum of the areas of its top and bottom circles, along with the area of its lateral surface (the curved surface that connects the two circles).

The formula for the lateral surface area of a cylinder is:

Lateral surface area = 2πrh

where r is the radius of the cylinder, h is the height of the cylinder, and π (pi) is a mathematical constant approximately equal to 3.14.

The formula for the area of a circle is:

Area of circle = πr^2

Using these formulas, we can calculate the total surface area of the cylinder as follows:

Area of top and bottom circles = 2 × π × r^2

= 2 × 3.14 × 2^2

= 25.12 square feet

Lateral surface area = 2 × π × r × h

= 2 × 3.14 × 2 × 6

= 75.36 square feet

Total surface area = Area of top and bottom circles + Lateral surface area

= 25.12 + 75.36

= 100.48 square feet

Therefore, the total surface area of the cylinder is 100.48 square feet.
