Answer:

5/2

Step-by-step explanation:

The 5^-3 and 5^6 cancel out to be 5^3. Then the 5^3 cancels out with the 5^2 in the denominator and leaves you with just a 5. The 2^2 makes the 2^3 in the denominator just 2. So, you are left with 5/2! Hope this helps.

f(d) = 11(1.01)^d

Part A:

f(d) = 11.79

11.79=11(1.01)^d (1.01)^d = 11.79/11 (1.01)^d = 1.071818 d = log 1.071818 /log 1.01

d = 6.97

Part B:

y- intercept is obtained when domain = 0

d = 0 ⇒ f(0) = 11(1.01)^0 = 11*1 = 11

f(d) = 11

Part C:

Average rate of change

A.f/Ad=

(f(7)-f(2))/(7-2) = (11(1.01)^7-11(1.01)^2)/5 = 0.57/5 =

The area of a circle is 113.04 in.^2. What is the radius of the circle?

Lelechka [254]

$\bf \textit{area of a circle}\\\\
A=\pi r^2\qquad 
\begin{cases}
r=radius\\
------\\
A=113.04
\end{cases}\implies 113.04=\pi r^2
\\\\\\
\cfrac{113.04}{\pi }=r^2\implies \sqrt{\cfrac{113.04}{\pi }}=r$
