The surface area S (r) (in square meters) of a spherical balloon with radius r meters is given by S (r)=4pir^2 The radius P (t) (in meters) after a seconds is given by P (t)5/3t
Write a formula for the surface area N (t)(in square meters) of the balloon after t seconds.

Sorry just need points

Step-by-step explanation:

one that is bigger than 3 1/2

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.
