A company is creating a box without a top from a piece of cardboard, but cutting out square corners with side length x.
Volgvan
Answer: Choice B) The expression (10-2x)(30-2x)x represents the volume of the box

----------------------------------------------------
----------------------------------------------------

The original width is 10 inches. The width reduces to 10-2x inches after we cut off the top two corners of the rectangle. We can think of it as taking 10 and subtracting off two copies of x like so: 10-x-x = 10-2x

Similarly, the length goes from 30 inches to 30-2x inches. This time we're taking off the top and bottom corners (focus on either side it doesn't matter). 

The height of the box is x inches due to this portion being folded up. 

Volume of box = (width)*(length)*(height)
Volume of box = (10-2x)(30-2x)x

Note: the units for the answer are in cubic inches which can be written as "in^3" (inches cubed).

13) Mark walks 3.4 miles per day. How<br> many days will it take him to walk 17.34<br> miles?
HACTEHA [7]

Answer:

5.1 days

Step-by-step explanation:

3.4 \: miles = 1 \: day \\ 17.34 \: miles \:  = x \: days

Cross Multiply

3.4x = 17.34

Divide both sides of the equation by 3.4

\frac{3.4x}{3.4}  =  \frac{17.34}{3.4}

x = 5.1

REY [17]

The true statement about the graph of the function f(x) = x3 - 2x2 + 4x – 8 is (B) The function has 1 real zero that occurs 1 time.

<h3>How to determine the true statement</h3>

The function of f(x) is represented as:

f(x)=x^3-2x^2+4x-8

Differentiate the function f(x)

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

Calculate the minimum value using:

x = -\frac b{2a}

So, we have:

x = -\frac {-4}{2*3}

x = \frac {2}{3}

Substitute 2/3 in f'(x)

f'(2/3)=3*(2/3)^2-4(2/3)+4

f'(2/3)=\frac 83

The value of f'(2/3) is greater than 0.

This means that the function f(x) has 1 real zero, and it occurs once at point (2,0)

Hence, the true statement is (b)
