Answer:
580.75
Step-by-step explanation: 11.50 * 40 =460
11.50 * 1.5 =`17.25*7= 120.75
120.75+460=580.75
By direct evaluation we conclude that the point (x, y) = (1, - 2) lies on the graph of the <em>quadratic</em> equation h(x) = - 2 · x². (Correct choice: C)
<h3>What ordered pair lies on the curve generated by a given function? </h3>
In this problem we have three <em>ordered</em> pairs to be checked on a given function by direct evaluation, a <em>ordered</em> pair lines on the curve of function if and only if the x-value of the <em>ordered</em> pair leads to the y-value by evaluating in the function. Now we proceed to evaluate each of the three points at the function presented in the statement:
(x, y) = (1, 4)
h(1) = - 2 · 1²
h(1) = - 2
By direct evaluation we conclude that the point (x, y) = (1, - 2) lies on the graph of the <em>quadratic</em> equation h(x) = - 2 · x². (Correct choice: C)

You need to work out the area so
Area of a rectangle is l x b
So
A= l x b
A= 8 x 4
A= 32
Therefor 32 cubic feet of dirt is needed
