It has 3 zeros, because its a polynomial of degree 3.
Dy/dx h = 32t - 16t^2
v = 32 - 32t
at Max hight speed is 0m/s
therefore
0 = 32 - 32t
t = 32/32 = 1 s
so it goes up to Max hieght in 1 s
and it takes another 1s to come back
thus time after launch to return to ground is 2s!
I believe it’s -6 square root of 2 + 3 square root of 4 + 6 square root of 5
The slope of the line we seek must me the same as the slope of the given line because THE LINES ARE PARALLEL.
The two lines never meet.
The slope of the given line is -7.
See it?
Plug -7 and the given point into the point-slope formula.
y - (-6) = -7(x - 9)
Solve for y.
y + 6 = -7x + 63
y = -7x + 63 - 6
y = -7x + 57
Did you follow?
Answer:
(x,y) = (2 - 1)
Step-by-step explanation:
2x - y = 5
5x + 2y = 8
y + 2x = 5
2y + 5 x = 8
