The function f(x) = −x2 − 5x + 50 shows the relationship between the vertical distance of a diver from a pool's surface f(x), in feet, and the horizontal distance x, in feet, of a diver from the diving board. what is a zero of f(x), and what does it represent? a x = 5; the diver jumps in the pool at 5 feet per second bx = 10; the diver jumps in the pool at 10 feet per second c x = 10; the diver hits the water 10 feet horizontally from the board dx = 5; the diver hits the water 5 feet away horizontally from the board

First of all, the root is , since

Then, since the represents the horizontal distance, and the height, we can read as "the height is zero when the diver is feet away from the board.

So, the answer is D.

i used to know how to do this in 7th but i forget easily

step-by-step explanation:

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.
