A storage box has a base area of 314.5 square inches and a height of 8.5 inches. What is the volume of 5 of these boxes. Enter y
nadezda [96]

Answer:

13366.25 in³

Step-by-step explanation:

The volume of a box can be found by multiplying the base area and height together.

Volume of a box

= base area ×height

= 314.5(8.5)

= 2673.25 in³

Volume of 5 boxes

= 5(2673.25)

= 13366.25 in³

What are the real zeros of f(x) = x3 – 3x2 – 4x? A. 0, 1, 4 B. 1, -1, 4 C. -1, 0, 4 D. 1, 0, -4
Natalka [10]

Step-by-step explanation:

f(x) = x^3 - 3x^2 - 4x

factor it:  (start by  factoring out the x that is common to all 3 )

       = x\left(x^2-3x-4\right)

next keep factoring the inside...

       = x\left(x^2+x-4x-4\right)\\=x  \left[x\left(x+1\right)-4\left(x+1\right)\right]\\=\bold{x\left(x+1\right)\left(x-4\right)}

So, the only way the function f(x) can be 0 is if:

  • either x=0, or
  • \left(x+1\right)=0, or
  • \left(x-4\right)=0

<h3>Answer:</h3>

               <em>C.</em> \{-1,0,4\}
