A football thrown by a quarterback follows a path given by hx=-0.0095x2+x+7, where h is the height of the ball in feet and x is

Wewaii [24]

Answer:

The ball can be knocked down at a horizontal distance of 3.09 feet or 102.17 feet from the marshal.

Step-by-step explanation:

We have the function that represents the height h (x) of the ball $h(x) = -0.0095x^2 + x + 7$

Where x is the horizontal distance of the ball.

We want to find the horizontal distance the ball is at (horizontal distance between the field marshal and the ball) when it is at a height of 10 feet.

To do this, we must do h (x) = 10

$10 = -0.0095x^2 + x + 7\\0 = -0.0095x^2 + x -3$

Now we must solve the second degree equation. For this we use the formula of the resolvent:

$\frac{-b + \sqrt{b ^ 2 - 4 * a * c}}{2a}$

and

$\frac{-b - \sqrt{b ^ 2 - 4 * a * c}}{2a}$

$\frac{-1 + \sqrt{1 ^ 2 - 4 * (- 0.0095)(-3)}} {2 (-0.0095)} = 3.09$ ft

and

$\frac{-1 - \sqrt{1 ^ 2 - 4 * (- 0.0095)(-3)}} {2 (-0.0095)} = 102.17$ ft

Then, the ball can be knocked down at a horizontal distance of 3.09 feet or 102.17 feet from the marshal.

Manuela solved the equation below. What is the solution to Manuela’s equation?

BabaBlast [244]

For this case we have the following equation:

$2 (x + 2) = x-4$

Applying distributive property to the terms within the parentheses on the left side of the equation we have:

$2x + 4 = x-4$

Subtracting "x" on both sides of the equation we have:

$2x-x + 4 = -4\\x + 4 = -4$

Subtracting 4 on both sides of the equation we have:

$x = -4-4\\x = -8$

Answer:

$x = -8$
