Answer:
d = 8.6
Step-by-step explanation:
a^2 + b^2 = c^2
7^2 + 5^2 = c^2
49 + 25 = c^2
74 = c^2
Now you take the square root of 74 and c^2
If you put the square root of 74 in a calculator you get about 8.6
So c = 8.6 or d = 8.6
Answer:
the maximum height of the ball is 81.125 feet above the ground. when the ball is at its peak, the ball is 156.25 feet away from home plate.
Step-by-step explanation:
x = d
y = h
to find the x coordinate of the vertex of a parabola, use the equation
x = -b/2a
y = ax^2 + bx+ c
y = – 0.0032x^2 + x + 3
x = -1 / 2 • - 0.0032
x = 156.25
plug x into original equation to find the the y coordinate of the vertex
y = – 0.0032 • (156.25)^2 + (156.25) + 3
y = – 0.0032 • 24414.0625 + 159.25
y = – 78.125 + 159.25
y = 81.125
The answer is 3a+b=a-15. Substitute the equation where b is.

Answer:
(x+3) (x+4) (x−5)
Step-by-step explanation:
(x+3) (x+4) (x−5)
When substituting x as 5 the expression becomes 0.
When substituting x as -4 the expression becomes 0.
When substituting x as -3 the expression becomes 0.
