Juan is hiking up a mountain starting at an elevation of 800 feet. every hour, he is 2000 feet higher in elevation.

which function, h(t), where t is time in hours, represents juan's height over time?

1. h(t)=2800t
2. h(t)=800t+2000
3. h(t)=2000t
4. h(t)=2000t+800

answer: its c because when it has a magnet next to it it will move away from the mixture. hope this

step-by-step explanation:

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
