The function f(x) = 150 * (1.3) ^ 4 represents the number of bikes sold at Peer's Bike store in months. The graph represents the amount of bikes sold at Cycles R Us bike store in the same time period? During Week 0, how many more bags were sold out at Peers bike shop than at Cycles are us? Explain.

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.

8+10

step-by-step explanation:

you multiply 4 by 2 and 5 by 2

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years

step-by-step explanation:

the answer should be a. snail
