Evaluate f(x) = –x2 + 1 for x = –3. –9 4 –4 –8

Klio2033 [76]

Answer:

-63

Step-by-step explanation:

Write the problem as a mathematical expression.

$f(x)=-x^2+1$ $for$ $x =3-9$ $4-4-8$

Simplify 4−4−8 to substitute in f(x)=−x^2+1

Subtract 4 from 4

$0-8$

Subtract 8 from 0

$-8$

Replace the variable x with −

8 in the expression

$f(-8)=-(-8)^2+1$

Simplify

$f(-8)=-64+1$

$f(-8)=-63$

Answer = -63

mr_godi [17]

Answer:

16 pots

Step-by-step explanation:

We first need to find out the amount of dirt that can be filled into a single flowerpot.

We use the formula to find the cylinder's volume.

π $r^{2}$ $* h$

Height is equal to ten, Radius is equal to 7.

49π $* 10$

≈ 1539.38

25,000 divided by 1539.38

≈ 16.24

After 5.75 hours, Kyler had finished painting 62.5% of his house. He needs to paint a total of 4,000 square feet on his house. A

First, we are going to find the painted area of his house. We know that the total area he needs to paint is 4000 square meters, so 4000 is the area of this house. Now, to find the 62.5% of that area, we are going to multiply it by $\frac{62.5}{100}$ :
Painted area= $(4000)(\frac{62.5}{100})=2500$

Now, to find <span>rate, in square feet per hour, we are going to divide the painted area by the number of hours:
Rate=</span> $\frac{2500}{5.75} =434.78$

We can conclude that Kyler paints at a rate of 434.78 square feet per hour.
