A box is to be made out of a 8 cm by 20 cm piece of cardboard. Squares of side length x cm will be cut out of each corner, and t

hen the ends and sides will be folded up to form a box with an open top.
(a) Express the volume V of the box as a function of x.

V=

(b) Give the domain of V in interval notation. (Use the fact that length and volume must be positive.)

(c) Find the length L, width W, and height H of the resulting box that maximizes the volume. (Assume that W?L).

L=

W=

H=

Enter the missing value into the box to complete the ratio comparing 75 centimeters to 3 meters. 1 to
Alex_Xolod [135]
The ratio for the problem above is one to four. A ratio is a relationship between number which describes how many times the second number contains the first number. The problem above gave two metric unit of length which are the centimeter and meter and the ratio between those two is one to a hundred. Therefore, we have a comparison between two amounts which are 75 and 300 and we can conclude a ratio of one to four.

Walking lights are placed around the perimeter of rectangular garden 30 feet be 16 feet and are placed 18 inches apart. How many
Masteriza [31]
Well we can find the perimeter by using the formula P=2L + 2W 
P=2(30) + 2(18)      P=60+36     P=96
I believe we can divide the perimeter by 18 to find the total amount of lights needed. 
96÷18=5.333333 
So we know at least 5 lights are needed.
I'm not sure if I'm correct, but I hope this helped anyways :)

The graph attaches shows the function f(x) and the table represents the function g(x)
Fed [463]

Answer:

<u>Statement D is true</u>

Step-by-step explanation:

We should know the following:

x-intercept is the value of x when y = 0

y-intercept is the value of y when x = 0

As shown on the graph, we can deduce the following:

For f(x) : at y = 0 ⇒ x = 1  And at x = 0 ⇒ y = -1

<u>So, for f(x) ⇒ x-intercept = 1  & y-intercept = -1   </u>

For g(x) : at g(x) = 0 ⇒ x = -1  And at x = 0 ⇒ g(x) = 1

<u>So, for g(x) ⇒ x-intercept = -1  & y-intercept = 1  </u>

Comparing the results with the given options:

A) the x-intercept of f(x) is equal to the x-intercept of g(x)          (<u>Wrong)</u>

B) the y-intercept of f(x) is equal to the y-intercept of g(x)          (<u>Wrong)</u>

C) the y-intercept of f(x) Is greater than the y-intercept of g(x)   (<u>Wrong)</u>

D) the x-intercept of f(x) is greater than the x-intercept of g(x) ​   <u>(true)</u>
