The answer is 10 because there is 8 ounces in both a glass and cup
Ground: y = 0
- 16t² + 128t + 50 = 0
Apply quadratic equation.
t = 0, 8 (rounded to the nearest second)
8 seconds
Not quite sure what you mean but if you want to multiply a fraction by a whole number you can turn the whole number into a fraction by just putting a one under it.
1/2*5=1/2*5/1
If we put the parabola in a coordinate system with vertex at the origin and facing the positive x axis. We have the following points lying on the curve:
(4, 8), (4, -8)
For parabola facing right:
y2 = 4ax
Substituting either coordinates to solve for a:
a = 4
Therefore, the microphone should be placed 4 inches from the bottom of the disk.
<span> 9x^2 - 18x - 7
--------------------
(3x + 1)
</span> (3x +1)(3x - 7)
= ------------------------
(3x + 1)
= 3x - 7
