Answer:
Step-by-step explanation:
y = ax² + bx + c
Plug the points into the equation to get a system of 3 equations with 3 unknowns a, b, and c.
-27 = 4a - 2b + c
-42 = 9a + 3b + c
-12 = a + b + c
(a,b,c) = (-4,1,-9)
y = -4x² + x - 9
38/2 is 19
38-238-2= -202
38+238+2= 278
The equation for finding the area of a triangle is (bh)/2.
(The slash is a division sign)
So, with this equation, it would be (19*12)/2.
That would equal 114. So the answer is 114 ft squared.
