Answer:
a. 7x/3x-3
Step-by-step explanation:
The root of this parabola are x'=2 & x'' = 4, these are the value of x intercepts. The midpoint = (4-2)/2 = 1
Answer:
114.89 V
Step-by-step explanation:
Watts are a measure of power, and there is an equation that relates power, voltage, and resistance. It goes like this:
P=(V^2)/R
Now to find the voltage you want to solve for V
PR = V^2
V = ![\sqrt{PR}](https://tex.z-dn.net/?f=%5Csqrt%7BPR%7D)
Now substitute your numbers into the equation and you get your answer
V = ![\sqrt{(60)(220)}](https://tex.z-dn.net/?f=%5Csqrt%7B%2860%29%28220%29%7D)
V = ![\sqrt{13200}](https://tex.z-dn.net/?f=%5Csqrt%7B13200%7D)
V = 114.89 V

We need the numbers but usually the first quart is before the median which is the number in middle, hope that made sense
