Answer:

Step-by-step explanation:

The explicit formula for a geometric sequence is

f(n) = f(1) $(r)^{n-1}$

where f(1) is the first term and r the common ratio

Here f(1) = 64 and r = $\frac{f(2)}{f(1)}$ = $\frac{16}{64}$ = $\frac{1}{4}$ , then

f(n) = 64 $(\frac{1}{4}) ^{n-1}$ → A

How do i evaluate (7 to the power of 2)to the power of 3)=7 to the power of 5

kakasveta [241]

Step-by-step explanation:

$(7^2)^3=7^5\qquad\bold{FALSE}\\\\\text{because}\\\\7^2=7\cdot7\\\\(7^2)^3=(7\cdot7)^3=(7\cdot7)\cdot(7\cdot7)\cdot(7\cdot7)=\underbrace{7\cdot7\cdot7\cdot7\cdot7\cdot7}_6=7^6\\\\\text{or use}\ (a^n)^m=a^{nm}\\\\(7^2)^3=7^{2\cdot3}=7^6$

If ADE ABC in this diagram, which pair of ratios must necessarily be equal?

ad-work [718]

Answer:

$\frac{AD}{AB}=\frac{AE}{AC}=\frac{DE}{BC}$

Step-by-step explanation:

we know that

Triangle ADE and Triangle ABC are similar

therefore

the ratio of their corresponding sides are equal

$\frac{AD}{AB}=\frac{AE}{AC}=\frac{DE}{BC}$

Answer:

50.3

Step-by-step explanation:

Volume = pi * h * r^2 *** Diameter = 2 * radius

Substitute

Volume = pi * 4 * (4/2)^2

Simplify

Volume = pi * 4 * 4

Simplify

Volume = 16 pi, which is approx. 50.3
