Answer:

C. 21.98

Step-by-step explanation:

In this case, you would have to multiply 3.14 times 7. If you didn't have the diameter, and all you had was the radius, you had find half of seven, which is 3.5, multiply that by 2, and finally multiply that answer by 3.14. Hope this helps! Have a nice day :D

What is the expression for f(x) when we rewrite <br> (5⁻⁴ˣ⁺⁷)÷(125x) as 5^f(x)
alexandr402 [8]

Answer: The answer is f(x) = -7x + 7.


Step-by-step explanation:  We are give a relation as follows :

5^{-4x+7}\div 125^x=5^{f(x)}.

From here, we need to find the expression for f(x).

Here, we will be using the following properties of exponents :

(i)~\dfrac{a^x}{a^y}=a^{x-y}.\\\\(ii)~a^x=a^y~\Rightarrow x=y.

We have

5^{-4x+7}\div 125^x=5^{f(x)}\\\\\Rightarrow5^{-4x+7}\div 5^{3x}=5^{f(x)}\\\\\\\Rightarrow \dfrac{5^{-4x+7}}{5^{3x}}=5^{f(x)}\\\\\\\Rightarrow 5^{-4x+7-3x}=5^{f(x)}}\\\\\Rightarrow 5^{-7x+7}=5^{f(x)}\\\\\Rightarrow -7x+7=f(x).

Thus, the required expression is f(x) = -7x + 7.

F(x)=(x+4) 2 −25<br><br> smaller x =<br><br> larger x = <br><br> NEED THIS ASAP
miss Akunina [59]

f(x)=(x+4) ^2 −25

to solve set equal to zero

0 =(x+4) ^2 −25

add 25 to each side

25 = (x+4) ^2

take the square root of each side

square root (25) =(x+4)

+- 5 = (x+4)

5 = x+4      -5 = x+4

subtract 4 from each side

1 =x            -9 =x
