Answer:
I think the answer is 432 cubic inches( in^3). Answer is the first option.
Step-by-step explanation:
Since the x-intercepts are -20 and 40, the line of symmetry is x = (-20 + 40)/2 = 10.
Now we have y = a(x - 10)² + 30, where a is an unknown constant. We can find a by using an x-intercept point.
=> (0) = a[(40) - 10]² + 30
=> 900a + 30 = 0, a = -1/30.
Hence the rule is y = -(x - 10)²/30 + 30.

Answer:
Step-by-step explanation:
Step 1: Write the correct equation y=k/x. Inverse variation problems are solved using the equation Inverse. When dealing with word problems, you should consider using variables other than x and y, you should use variables that are relevant to the problem being solved. Also read the problem carefully to determine if there are any other changes in the inverse variation equation, such as squares, cubes, or square roots.
Step 2: Use the information given in the problem to find the value of k, called the constant of variation or the constant of proportionality.
Step 3: Rewrite the equation from step 1 substituting in the value of k found in step 2.
Step 4: Use the equation found in step 3 and the remaining information given in the problem to answer the question asked. When solving word problems, remember to include units in your final answer.
