X=1. if 1 to the second power=1 and four times 1=4, 1+4-5=0.
The equation of the height as a function of time for this case is given by:
h (t) = - 16t ^ 2 + 10t + 100
By the time the egg hits the ground we have:
-16t ^ 2 + 10t + 100 = 0
We look for the roots of the polynomial:
t1 = -2.2069555463432966
t2 = 2.8319555463432966
As it is about time, we use the positive root:
t = 2.83 s
Answer:
it hits the ground at:
t = 2.83 s
If it has a slope of -4, you need to find b.
So you want to plug in your coordinate values for x and y to solve.
5=-4(-1)+b
5=4+b you then subtract 4 from both sides to find the answer for b.
1=b
So your equation would be:
y=-4x+1
