1. Erin hits a golf ball off a tee. The height, yin yards, of the ball off the ground is given by
Sladkaya [172]

Answer:

The maximum height of the ball is 28.2 yards.

Step-by-step explanation:

When we have a quadratic equation in the following format:

y = ax^{2} + bx + c

The maximum value happens when

x = x_{v} = \frac{-b}{2a}

The maximum value will be y(x_{v})

In this problem, we have that:

y = -0.0018x^{2} + 0.45x + 0.05

So

a = -0.0018, b = 0.45, c = 0.05

x = x_{v} = \frac{-b}{2a} = \frac{-0.45}{2*(-0.0018)} = 125

The maximum height is:

y(125) = -0.0018*(125)^{2} + 0.45*125 + 0.05 = 28.2

The maximum height of the ball is 28.2 yards.

When x = 8, y=10 , find y when x = 64
worty [1.4K]

Answer:

When x = 64, y = 80.

Step-by-step explanation:

Since the origanal value was 8 and now it´s 64, lets divide to see how much was multiplied. Then lets multipliy it with that number.

64 / 8 = 8

Soo..8 x 10 = 80.
