Answer: The second option.

Step-by-step explanation:

1. Calculate the first volume assuming that the figure is completed (with no missing part). Therefore, you must apply the formula for calculate the volume of a square prism:

$V_A=s^{2}*h$

Where s is the side of the base and h is the height.

2. Then:

$V_A=(40cm)^{2}*50cm=80,000cm^{3}$

4. The volume of the missing part is calculated with the formula of a rectangular prism:

$V_B=l*w*h$

Where l is the lenght, w is the width and h is the height. Then:

$V_B=(40cm)(40cm-35cm)(50cm-25cm)=5,000cm^{3}$

5. Therefore, you must subtract both volumes to obtained the volume of the figure:

$V_f=80,000cm^{3}-5,000cm^{3}=75,000cm^{3}$

A 5 year lease for a office space states that the annual rent is 62,000 for the first year and will increase by 7% each addition

Jet001 [13]

First year- 62,000
Second year- 7% increased in rent= 66,340
Third year- 7% increased in rent (66,340)= 70,984
Fourth year- 7% increased in rent (70,984)= 75,953
Fifth year- 7% increased in rent (75,953)= 81,270.

Total 5 years lease- 356,547.

Determine the average rate of change of f (x) = x² - 10x + 5 over the interval [-4, 4].<br> =<br> -

jeka57 [31]

Answer:

f ( x ) = ( x - 5 ) ² - 20

Step-by-step explanation:

1- Add the same value to both sides

f ( x ) = x ² - 10x + 5

2- Add 25 to the expression

f ( x ) + ? = x ² - 10x + ? + 5

3- Add 25 to the left-hand side

f ( x ) + ? = x ² - 10x + 25 + 5

4- Factor the expression

f ( x ) + 25 = x ² - 10x + 25 + 5

5- Move the constant to the right

f ( x ) + 25 = ( x - 5 ) ² + 5

6- Calculate

f ( x ) = ( x - 5) ² + 5 - 25

One question in a survey about what kind of cars people prefer to drive is:

Aneli [31]

<h3>Answer: C) bias</h3>

The question is biased toward mothers, and does not consider women who do not have kids. A biased question leans toward a certain group, or set of groups, of people; at the same time, other groups are left out and not represented. One way to remove the bias is to ask "Would you prefer a minivan or a convertible?".
