Jennie, Lisa, and Jisoo have decided to race from the top of a hill to its bottom. Jennie rides a bicycle through a downhill trail which is 700 meters long. It takes her 5 minutes to reach the bottom of the hill, Lisa takes a cable-car and the cable car follows a straight wire from the top to the bottom which is 400 m long. It takes her 3 minutes. Jisoo drives a car through a winding road that is 1500 m long and it takes her 6 minutes Find out who has the highest speed, and who has the highest velocity, among the three of them.

hope it

step-by-step explanation:

x^(1/6) · x^(1/6) · x^(1/6)   ·x^(1/6) = x^(4/6)   since we add the exponents

4/6 can be simplified to 2/3

the simplified form is x^(2/3)

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
