Answer:
Acute angle
Step-by-step explanation:
Obtuse are a bit slanted Right angles are Shaped like an L
H = - 16 t² + 32 t + 9
The maximum height is at the vertex of the parabola:
t = - b / (2 a ) = - 32 : ( - 32 ) = 1 s
The ball will reach maximum height in 1 second.
h max = - 16 * 1² + 32 * 1 + 9 = - 16 + 32 + 9 = 25 m
The maximum height is 25 m.
7x-6=5(x+4)
7x-6=5x+20
-5x -5x
2x-6=20
+6 +6
2x=26
/2 /2
X=13
