Answer: C— 9 m
Steps:
a^2 + b^2 = c^2
12^2 + b^2 = 15^2
144 + b^2 = 225
b^2 = 81
b = 9
The data has a peak at x=5, so we expect it to be modeled with a parabola that opens downward. That is the x² coefficient will be negative.
For x=1, the third choice gives a better approximation to (x, y) = (1, 32) than does the first choice. It is appropriate to choose
... y = -11.41x²+154.42x-143.9
_____
The quadratic regression function of a graphing calculator confirms this choice.
Answer:
Alright well all you need to do is Graph using the slope and y- intercept so with that the Answer is
Slope: - 2/3
Y- intercept: 7/3 Hope this helps :)
