I hate APEX!
A is right since the graph would start at 2 and go towards negative infinity
D is right both graphs approach +2 as thier highest values
The function would be -1 bc the formula is y1-y2/x1-x2 so 8-7/1-2 which is 1/-1 and if you simplify that you get -1
I’m 99% sure I’m correct
Hope this helps :)
Answer:
The surface area is
Step-by-step explanation:
we know that
The surface area of a square pyramid is equal to the area of the square base plus the area of its four lateral triangular faces.
so
we have
substitute the values
Check the picture below
the angle is in degrees, thus, when taking the sine, make sure your calculator is in Degree mode
Finding the slope, you get [4-(-2)]/[-1-2]=6/-3 = -2
Plugging (2,-2) and -2 into the formula y=mx+b, you get that -2=-4+b.
Therefore, b=2, making the equation y = -2x+2
