PLEASE HELP ME Use the function below to find f(2). f(x) = 1/3 x 4^x

Anna71 [15]

f(2) This means that x is 2, so you plug in 2 for x in the equation

$f(x)=\frac{1}{3} (4^x)$

$f(2)=\frac{1}{3}(4^2)$

$f(2)=\frac{1}{3} (16)$

$f(2)=\frac{16}{3}$

Your answer is D

What is the center and radius of the circle? (x-3)2 + y² = 4

Kipish [7]

Answer:

center = (3, 0)

radius = 2

Step-by-step explanation:

Standard equation of a circle: $\sf (x-h)^2+(y-k)^2=r^2$

(where (h, k) is the center of the circle and r is the radius)

Given equation:

$\sf (x-3)^2+y^2=4$

Rewrite in standard form:

$\sf \implies (x-3)^2+(y-0)^2=2^2$

Therefore

center = (3, 0)
radius = 2
