A firework is launched from a platform above the ground and follows the path of the equation below where h=height in feet and t=time in seconds H(t)=-16 squared +64t +40

How long did it take the firework to reach it maximum height (Round to the nearest whole number)?

What was the highest point the firework reached?

How long was the firework in the air. (Round to the tenths place.)

What was the initial height of the firework?

the least common denominator is 40

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?

a)(x-2)^2+(y-1)^2=9

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