A ball is at it maximum height when its velocity is zero. y = 4+30t - 16t^2 is the formula, where
V = V(0) -32t
0 = 30- 32t
t = 15/16 seconds when its velocity is zero.
It is not at its maximum height but is falling.
Answer:
(-3, 0) and (-1, 0)

It’s a reflection across the line x=3
Answer:
y = -4, x = -9
Step-by-step explanation:
System: -2x + 5y = -2, x - 3y = 3
Multiply the second equation: 2x - 6y = 6
Elimination:
-2x + 5y = -2
<u>+ 2x - 6y = 6</u>
- y = 4 --> y = - 4
Plug in: x - 3(-4) = 3
x + 12 = 3
x = -9
let
x--------> the length side of the legs of a right triangle
H------> hypotenuse
we /know that
in a right triangle
Applying the Pythagorean Theorem
H²=x²+x²------->H²=2x²-----> solve for x-------> x=H/√2
H=7 m
so
x=7/√2------->(7√2) /2 m------> 4.9497 m
the answer is
in simplified radical form------> (7√2) /2 m
as a decimal rounded to four places-------->4.9497 m
