Answer:

The answer would be the very last explanation.

Step-by-step explanation:

Considering x=63 it shows that x = 18 + 45 which it is, and it also represents the equation by stating how he spent 18 dollars while shopping and he has 45 dollars left. So meaning he had more in the start unlike the other situations.

A ball is thrown upward and outward from a height of 8 feet. The height of the ball, f(x), in feet, can be modeled by 1(x) -0.1x

shutvik [7]

Answer:

maximum height: 498 ft
distance from point of release: 70 ft

Step-by-step explanation:

A graphing calculator can show the answers to these questions.

___

For quadratic ax²+bx+c, the x-value of the vertex is ...

x = -b/(2a)

For the given expression, the vertex is ...

x = -14/(2(-0.1)) = 70

The distance from the point of release to the point of maximum height is 70 feet.

The height of the ball at that point is ...

f(70) = (-0.1·70 +14)70 +8 = 7·70 +8 = 498 . . . . feet

The maximum height is 498 feet.
