A farm in Canada has 228 alpacas. After 8 years, the alpaca population decreased to 186 alpacas. The function f (t)= 228 (0.975)^t models the population of alpacas in the Canadian farm as a function of time in years. How many alpacas will there be in 20 years?

answer: no

step-by-step explanation:

you are only given the cost not the amount of pounds.

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.
