Find f(-3) for f(x) = 4(2)^x. ОА. 1/8 O B. -32 O C. -24 OD. 1/2

Ipatiy [6.2K]

Answer:

Step-by-step explanation:

using the rule of exponents

$a^{-m}$ = $\frac{1}{a^{m} }$

substitute x = - 3 into f(x)

f(- 3) = 4( $(2)^{-3}$ = 4 × $\frac{1}{2^{3} }$ = 4 × $\frac{1}{8}$ = $\frac{1}{2}$

A vat of milk has spilled on a tile floor. The milk flow can be expressed with the function r(t) = 4t, where t represents time i

Likurg_2 [28]

R(t) = 4t
A(r) = π(r^2)

a) A(t) = A[r(t)] = π[r(t)]^2 = π[4t]^2 = 16π(t^2)

b) t = 4,

A(4) = 16*3.14*(16)^2 = 12,861.44

2(x+3)^2+2(y)^2=32 what is the center point of the circle and how long is the radius

spayn [35]

Answer:

center (-3, 0)
radius 4

Step-by-step explanation:

The standard form equation of a circle is ...

(x -h)^2 +(y -k)^2 = r^2 . . . . . . . . . center at (h, k), radius r

Divide your given equation by 2 to put it into standard form:

(x +3)^2 +y^2 = 16

Comparing to the above, we see ...

h = -3
k = 0
r = √16 = 4

The center point of the circle is (-3, 0); the radius is 4 units long.
