Answer 1
Answer: Choice C)   x^4 - 2

Explanation:

If the exponent is negative, then that means we apply the reciprocal. So something like x^(-2) becomes 1/(x^2). A polynomial cannot have a variable in the denominator like this. So we can rule out choices A, B, and D. Choice C is the only thing left. It is a polynomial because the exponent is a positive whole number.

Answers

Answer:

Step-by-step explanation:

X > 3/7

We know that the student sleeps in at least 3 days, but we don't know what the exact number is, we use an inequality where X is greater than or equal to 3 out of the 7 days.

Write a compound interest function to model each situation. Then find the balance after the given number of years.

$50,000 invested at a rate of 3% compounded monthly; 6 years

$43,000 invested at a rate of 5% compounded annually; 3 years

$65,000 invested at a rate of 6% compounded quarterly; 12 years​

Answers

Answer:

See explanation

Step-by-step explanation:

The standard compound interest formula is [tex]A = P(1+\frac{r}{n})^{nt}[/tex] where:

P is the principal amount

r is the interest rate (typically as a percentage)

t is the time

n is the times compounded per unit of time

So,

1)  [tex]A = 50000(1+\frac{0.03}{12})^{(12)(6)} =59847.42[/tex]

2) [tex]A = 43000(1+\frac{0.05}{1})^{(1)(3)} =49777.88[/tex]

3) [tex]A = 65000(1+\frac{0.06}{4})^{(4)(12)} =132826.08[/tex]

Part A: What is the shortest distance between the gymnasium and the library? Round your answer to the nearest tenth of a kilometer.


Part B: Gabe walks the shortest distance from his house to the gymnasium, then the shortest distance to the library. What is the total distance Gabe walked?

Answers

Answer:

4.5 km

10.3 km

Step-by-step explanation:

The shortest distance from gymnasium to library:

Each square box representing 1 unit

1unit = 1 km

A.)

Distance, d ;

Using Pythagoras :

d = sqrt(2² + 4²)

d = sqrt(4 + 16)

d = sqrt(20)

d = 4.47

d = 4.50 (nearest tenth)

Shortest Distance from gymnasium to library

B.)

shortest distance from his house to the gymnasium, then the shortest distance to the library

House to gymnasium (d1) :

d1 = sqrt(3² + 5²)

d1 = sqrt(9 + 25)

d1 = sqrt(34)

d1 = 5.83

Gymnasium to Library (d2) :

d2 = sqrt(2² + 4²)

d2 = sqrt(4 + 16)

d2 = sqrt(20)

d2 = 4.47

Total distance = (d1 + d2) = (5.83 + 4.47) = 10.3km

An aquarium can hold 48 gallons of water. If the aquarium is filled with containers holding 12 quarts of water each, how many containers will it take to fill the aquarium with water?

Answers

Answer: 16 containers

Step-by-step explanation:

First and foremost, we should note that:

4 quarts = 1 gallon

48 gallons = 48 × 4 = 192 quarts

Since the container holds 12 quarts of water each, the number of containers needed to fill the aquarium with water will be:

= 192 quarts / 12 quarts

= 16 containers

Show that the equation is a linear equation by writing it in a slope-intercept form. Show your work

Answers

Answer:

Slope- intercept form       y = 200 x + 500

Step-by-step explanation:

Explanation:-

Given that the equation

        200x - y + 500 = 0

where   y, the number of pairs of skates the factory has in the warehouse, and x be the number of hours

The slope-intercept form

                 y = m x +C

Given equation  200x - y + 500 = 0

                           200 x + 500 =y

                        y = 200 x + 500

Slope of the equation m = 200 and y-intercept 'C' = 500

Answer: B. Jessie sold 2 cars in the first week and x number of cars in the second week, earning a commission of $400 on each car.

Step-by-step explanation:

The options include:

A. Jessie earned a total commission of $800 in the first week and x dollars in the second week.

B. Jessie sold 2 cars in the first week and x number of cars in the second week, earning a commission of $400 on each car.

C. Jessie sold 1 car in the first week, earning $800, and x number of cars in the second week, earning a total commission of $1,200.

D. Jessie earned a commission of $800 on each car in the first week and $400 on each car in the second week, selling x number of cars each week.

The situation that could be described by this expression will be option B "Jessie sold 2 cars in the first week and x number of cars in the second week, earning a commission of $400 on each car". This will be:

= (400 × 2) + 400(x)

= 800 + 400x

Answer:

Step-by-step explanation:

Area of shaded region

= area of circle -area of square

[tex]\boxed{area \: of \: circle = \pi {r}^{2} }[/tex]

Given that radius= 10cm, r= 10cm.

[tex]\boxed{area \: of \: square = side \: \times side}[/tex]

Let the length of a side of the square be x cm.

Applying Pythagoras Theorem,

10² +10²= x²

100 +100= x²

x²= 200

[tex]x = \sqrt{200} [/tex]

Area of square

= x²

= 200cm²

Area of shaded region

Answer:

14. She deposited $15.50 into her bank.

15. The width would be 900.

Step-by-step explanation:

14. 245.60 + x = 261.10

x = 15.50

245.60 + 15.50 = 261.10.

She deposited $15.50 into her bank and resulted in her new bank balance appearing as $261.10.

15. Width is 900 cm

Length is 12 cm.

A = L X W = 108

A = L * 3/4L

108 = 3/4L2

Divide both sides by 3/4: multiply both sides by the inverse of 3/4 or 4/3.  

(4/3)*108 = L2

144 = L2

√144 = L

12 = L

W = 3/4*12

W = 9

Before we finish:

 

A = 108 = 9 x 12 = 108

W/L = 3/4 = 9/12 = 3/4

The width of the rectangle would be 3/4.
