Answer:

Step-by-step explanation:

PART A: 2x^5 + 3x^2-3

It is a fifth degree polynomial because, the highest degree is 5 and it is in the standard form since, the polynomial is written in descending order i.e, from highest degree to the least

part B:

Closure property is applicable to the subtraction of polynomials.

for example 2x^4+2x^2-5 is a polynomial and 2x^3+2x+2 is also a polynomial.

if we subtract these two polynomials, the outcome

2x^4-2x^3+2x^2-2x-7 is also a polynomial

Answer:

D. Henry's started farther, went faster

Step-by-step explanation:

Henry's balloon traveled 18 additional miles (from 30 to 48) in 2 hours, so had a speed of 18mi/(2h) = 9 mi/h. The equation for his position could be ...

y = 9x +30 . . . . . 9 is the rate of change; 30 is the initial value

Comparing this to Tasha's position function, we see her balloon started 20 miles from town and traveled 8 miles per hour.

Henry started farther from town and traveled faster.
