Guys last question pls help

Answer:

(x²+8x+16)π in²

Step-by-step explanation:

Since were not given the diagram of the circle. Let's assume the radius of inner circle is x+4

radius r = x+4

Area of the circle = πr²

Area of the circle = π(x+4)²

Area of the circle = π(x+4)(x+4)

Area of the circle =π(x²+4x+4x+16)

Area of the circle = π(x²+8x+16)

Area of the inner circle in terms of pi is (x²+8x+16)π in²

24/2=12

8/2=4

answer is $4

Answer:

D, 18.

Step-by-step explanation:

1. We need to separate any value from x, so we must remove (-2/3) from the left side of the equation and place it on the right by dividing by (-2/3).

-2/3(x) = -12

2. We recognize that the negatives cancel each other out, so it cannot be A or B. Also, remember that dividing by a fraction or decimal will always increase the value of your answer. Therefore, the answer must be 18.

x = -12 times -3/2

x = 36/2

x = 18

Answer:

The interest will rack up to $7,200

The total will be $15,200

Step-by-step explanation:

the interest she pays is $7,000

the total amount she pays is $15,200

Jenna borrows $8,000 for college at a simple interest rate of 6%

she has 15 years to pay back the loan and interest

the interest can be calculated as follows

= 6/100 × 8,000

= 0.06 × 8000

= 480

= 480 × 15

= $7200

the total amount she pays can be calculated as follows

= $7200 +$8000

= $15,200

Hence the interest she pays is $7200 and the total amount is $15,200

The pressure exerted by the block can be obtained as 60 N/m².

The arithmetic operations are the fundamentals of all mathematical operations. The example of these operators are addition, subtraction, multiplication and division.

Since, the pressure is obtained as the ratio of Force to area.

It can be worked out using the following operation as,

Pressure = Force ÷ Area

⇒ 120 ÷ 2 = 60 N/m².

Hence, the pressure can be obtained as 60 N/m².

Answer:

Step-by-step explanation:

Answer:

A)

45% of customers were not satisfied with the graphics.

B)

22,500 people are expected to not be satisfied with the graphics.

6,500 people are expected to have no opinion.

C)

The majority of people are unsatisfied with the graphics.

Step-by-step explanation:

The company polled 1,000 out of the 50,000 people who had purchased the program.

42% was satisfied with the graphics.

And 13% had no opinion.

Part A)

When totaled, those satisfied, unsatisfied, and with no opinion should be 100%.

Since 42% are satisfied and 13% have no opinion, this leaves 100 - 42 - 13 or 45%.

So, 45% of customers were not satisfied with the graphics.

Part B)

Since 45% of the polled were unsatisfied with the graphics, 45% of the total 50,000 can also be expected to not be satisfied.

45% of 50,000 is 0.45(50000) = 22500.

So, 22,500 people are expected to not be satisfied with the graphics.

Likewise, 13% had no opinion.

So, 13% of 50,000 is 0.13(50000) = 6500.

6,500 out of the current 50,000 customers are expected to have no opinion with the graphics.

Part C)

Since the majority of people are unsatisfied with the graphics (45% > 42%), it is reasonable to create a new version with improved graphics.

Answer:

Step-by-step explanation:

Domain: 0<x<3.5

To get 3.5:  7/2=3.5

Negatives and decimals can't be used

Approximate maximum volume for this box?  55

The proper domain of Noah's graph should be 0 to 3.5 and the maximum of the graph is at y = 60.

It is required to find the approximate maximum volume for his box.

Coordinate geometry is defined as the study of geometry using the coordinate points. Coordinate geometry is required to provide a link between algebra and geometry through the use of line and curve graphs.

Given:

From the attached graph (see attachment), we have the following observations:

1.The x values starts from -1 and ends at 60

2.The domain of the graph is from 0 to 4 (i.e. x-values 0 to 4 have corresponding y-values on the graph)

3.x-values 0 to 3.5 have corresponding non-negative y-values

4.Other values of x have corresponding negative y-values

5.The maximum of the graph is at y = 60

Because the volume of a box cannot be negative, the x-values to use must correspond to non-negative y-values.

Hence, the proper domain of Noah's graph should be 0 to 3.5 and the maximum of the graph is at y = 60.
