Answer:
This is an isosceles triangle.
So, we have:
Tangent 32 = x/11
Tangent 32 (11) = x
x = 6.874
Let me know if this helps!
3(y+1)+2y=8
3y + 3 +2y = 8
5y +3 = 8
-3 -3
5y = 5

5 5
y=1
The sum of length and width is half the perimeter, so that sum is 26 inches.
If length and width were equal, they would both be 26/2 = 13 inches. Adding 2 inches to one dimension and subtracting 2 inches from the other will keep the sum the same and make them differ by 4 inches.
The length and width are 15 inches and 11 inches, respectively.
The answer is B. Plug in x^2 for f(x) which is y=-1/4x^2
The vertex is (0,0)
The focus is (0,-1)
The directrix is y=1
Graph is B.
