The graph shows the velocity f(t) of a runner during a certain time interval:
omeli [17]

Answer:

Option B

Step-by-step explanation:

  • (0,2)
  • (6,8)
  • (8,0)

Slope

  • m=8-2/6
  • m=6/6=1

And

  • m=0-8/8-6
  • m=-8/2
  • m=-4

These are acceleration

Y intercept is (0,2) as x coordinate is 0

This is initial velocity 2m/s

The runner stopped at 8s

Which of the following represents the sum of the polynomials below?
zysi [14]

Answer:

A

Step-by-step explanation:

First, you have to align the like terms next to each other so that it will be easier to combine like terms. (Like terms have the same variables and powers)

6x^3+(-2x^3)+2x^2+5x^2+9x+3x

Combine like terms:

(When combining like terms all you have to do is add/subtract the coefficients, number in front of variables, and leave the variable and exponents)

6x^3+(-2x^3)= > 6x^3-2x^3=4x^3

2x^2+5x^2=7x^2

9x+3x=12x

So, we get 4x^3+7x^2+12x
