The function f(x) = −x2 − 9x + 10 shows the relationship between the vertical distance of a diver from a pool's surface f(x), in
mote1985 [20]

Answer:

Zeros of a function: x = 1 and x = -10

Step-by-step explanation:

A zero of a function is the value of x when f(x) = 0. In other words it is the intersect point between x and y=f(x), when y =0.

First we need to make f(x)=0, so we would have: -x^{2}-9x+10=0.

If we factorize this quadratic function, we would have: (x+10)(x-1)=0

So we get x = -10 and x = 1.

  • x = 1 means that the diver hits the water 1 foot away horizontally from the board.
  • x=-10 means the diver hits the water 10 feet behind the diving board.

Hope it helps!

Suppose Marcus invests $750 at an annual rate of 6.25%. How long will it take until Marcus earns $125 in simple interest?
Naddik [55]
We know, S.I. = P * R * T / 100
Here, S.I. = 125
P = 750
r = 6.25

Substitute into the formula:
125 = 750*6.25*t / 100
4687.5 * t = 12500
t = 12500 / 4687.5
t = 2.67
t = 2 2/3

In short, Your Answer would be 8/3 Years

Hope this helps!
