Answer:
A
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k) = (2, 1), thus
y = a(x - 2)² + 1
To find a substitute (1, 0) into the equation
0 = a(1 - 2)² + 1
0 = a + 1 ( subtract 1 from both sides )
a = - 1
Hence
y = - (x - 2)² + 1 or
y = 1 - (x - 2)² → A
Slope is equal to rise over run. In this case there is a point at (0,-5), and (12,3). The change in the y is positive 8, and x positive 12. Because of the slope formula change in y over change in x, you could write this as 8/12, or 2/3. The equation would then be
y=2/3x-5
V = 1/3 l h w
V = 1/3 (12)(15)(9)
V= = 540
answer 540 m^3
