The first astronaut on mars tosses a rock straight up. The height, h, measured in feet after t seconds, is given by the function h(t) = -6^2+24t+6. A. After how many seconds will the rock be 30 feet above the surface?
B. After how many seconds will the rock be 10 feet above the surface?
C. How many seconds will it take for the rock to return to the surface?
D. The same action on earth is modeled by the equation g(t) = -16t^2+24t+6. On earth, how many seconds would it take for the rock to hit the ground?

domain is all the x values included in the

0 ≤ x ≤ 2

range is all the y values of the graph

-2 ≤ y ≤ 2

***keep in mind that there are different ways to show domain and range

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
