Answer:
option 4. The graph has zeroes at x = 15 an x = -15 and it opens upward.
Step-by-step explanation:
we have

This is the equation of a vertical parabola open upward (the leading coefficient is positive)
The vertex represent a minimum
The vertex is the point (0,-225)
The axis of symmetry is x=0 (y-axis)
Find the x-intercepts (values of x when the value of y is equal to zero)
For y=0

square root both sides

therefore
The graph has zeroes at x = 15 an x = -15 and it opens upward.
163-x=-52
first subtract 163 and you get -215
now it looks like -x=-215
then the negative signs cancel out and its now x=215
Answer:
12
Step-by-step explanation:
The angle equals 90 degrees so (8*12-6) would equal 90
hopefully i helped
I would go with C because if you do A then its all new students and thats one view D is the same. C seems like the best choice.
