On the day Alexander was born, his father invested $5000 in an account with a 1.2% annual
growth rate. Write a function, A(t), that represents the value of this investment t years after
Alexander’s birth.
Determine, to the nearest dollar, how much more the investment will be worth when Alexander
turns 32 than when he turns 17.

3 1/3 x 2 3/5 = 8 2/3

step-by-step explanation:

just multiply the first number by the second number to get your answer.

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.

51

step-by-step explanation:

73-22=51 the   mass number minus the amount of protons gives you the amount of neutrons
