Use a transformation to solve the equation. f – 12 = –35 A. f = –47 B. f = –23 C. f = 23 D. f = 47

andrew-mc [135]

F – 12 = –35

Here, we must solve for f

f - 12 = -35
+12 +12

f = -35 + 12
f = -23

Answer: f = -23

a sequence is defined by ths formula (n+1)=f(n)+3 the first term of the sequence is -4 what is the next term in the sequence

jenyasd209 [6]

How I understand from your writing next term is equal previous plus 3,
if 1st is -4, then next (second) should be -4+3= -1

A cone with height h and radius r has volume V = 13πr^2h. If the cone has a height of 6 in. and volume V = 8πx^2 + 24πx + 18π, w

torisob [31]

ANSWER

$r = x - \frac{3}{2}$

EXPLANATION

The volume of the cone is

$V=8\pi \: {x}^{2} + 24\pi \: x + 18\pi$

The height of the is 6 inches.

We put the values into the volume of cone to get.

$8\pi \: {x}^{2} + 24\pi \: x + 18\pi = \frac{1}{3} \times \pi \: {r}^{2} \times 6$

$8\pi \: {x}^{2} + 24\pi \: x + 18\pi = 2 \pi \: {r}^{2}$

Divide through by 2π.

$4 {x}^{2} + 12x + 9 = {r}^{2}$

The expression on the LHS is a perfect square trinomial.

$( {x - \frac{3}{2} })^{2} = {r}^{2}$

$r = x - \frac{3}{2}$
