Jeremy likes to paint. He estimates the number of paintings he completes using the function p(w)=1/3w+4, where w is the number of weeks he spends painting. The function J(y) represents how many weeks per year he spends painting. Which composite function would represent how many paintings Jeremy completes in a year?
a)P[J(Y)]=J(1/3w +4)
b)J[P(W)]=1/3 times J+4
C)P[J(Y)]=1/3 times J(Y)+4
d)J[P(W)=J(1/3w+4)

d

Step-by-step explanation:

this equation means number of paintings= weeks(rate)

a is incorrect because because you should not be plugging in the amount of weeks, b is incorrect because you cannot multiply 1/3 by J+4, if should be j(1/3w+4), and same with c.

i really hope that makes sense

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
