Answer:

The solutions are x = -4 and x = 4.

Step-by-step explanation:

Solving a quadratic equation:

We have to find x for which y = 0.

In this question:

y = 16 - x^2

So

16 - x^2 = 0

x^2 = 16

x = \pm \sqrt{16}

x = \pm 4

The solutions are x = -4 and x = 4.

If you are looking for the height of a pyramid and the volume is 18,069,333.33333 and the length and width are both 440 what is
makkiz [27]

Answer:

h=123,200

Step-by-step explanation:

First you must in the formula for the pyramid, which is

v=\frac{wlh}{3}

and as far as the question has gave us

V=18069333.33333

LW=440

1.) Plug those numbers into the the equation, which should be:

(18,069,333.33333)= \frac{(440)h}{3}

2.) Then isolate the "h" by dividing both sides by \frac{440}{3}, or multiplying its reciprocal, which is \frac{3}{440}

(\frac{3}{440}) 18,069,333.33333=\frac{440h}{3} (\frac{3}{440} )

3.) Simplify or round the numbers if you need to.

h= 123,200
