Answer: 180 Inchs
Reason:
75 / 5
180 Inchs = 15 Feet

Step-by-step explanation:
Graph the inequality x>13.
Answer:
The graph is attached.
Step-by-step explanation:
The open circle is because the inequality sign is >. If the sign is > or <, the circle is plotted open. If the sign is [tex]\geq[/tex] or [tex]\leq[/tex], the circle is plotted closed.
The sign is greater than, so the arrow is pointed to the right (where the numbers are going up).
The circle is plotted between 12 and 14 because that is point 13, like the inequality says.

The function F represents the revenue in dollars the school can expect to receive if it sells 220-12× coffee mugs for dollars each.
Options B,D, and E are correct as per the given Function of the revenue.
What is the function?A relationship between a group of inputs and one output is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.
A. At $2 per coffee mug, the revenue will be $196.
This statement is incorrect.
If the price per mug is $2, then the revenue would be (220 - 12x) * 2. If x = 12 (i.e. 12 mugs are sold), then the revenue would be (220 - 12(12)) * 2 = $176.
B. The school expects to sell 160 mugs if the price is $5 each.
This statement is correct.
To find the number of mugs sold at a given price, we need to solve the equation (220 - 12x) * x = revenue, where revenue is the expected revenue at that price.
However, the graph does not provide enough information to determine the number of mugs sold at a price of $5.
C. The school will lose money if it sells the mugs for more than $10 each.
This statement is incorrect. The graph shows that the revenue is increasing as the price per mug increases, up to a maximum revenue of about $1,000 when the price is $10 per mug. Therefore, the school will not lose money if it sells the mugs for more than $10 each.
D. The school will earn about $1,000 if it sells the mugs for $10 each.
This statement is correct. The graph shows that the maximum revenue occurs when the price per mug is about $10. At this price, the revenue is approximately $1,000.
E. The revenue will be more than $700 if the price is between $4 and $14.
This statement is correct.
The graph shows that the revenue is increasing in this price range, and the minimum revenue occurs when the price per mug is about $18. Therefore, the revenue will be more than $700 if the price is between $4 and $14.
F. The expected revenue will increase if the price per mug is greater than $10.
This statement is incorrect. The graph shows that the revenue is increasing as the price per mug increases up to $10, but then it starts to decrease. Therefore, the expected revenue will decrease if the price per mug is greater than $10.

1 - Find the values of x for which the combined function h(x) = f(x)/g(x) is undefined if f(x) = 5x + 1 and g(x) = x^2 - 9.
x = ±3
x = 3
x = -3
x = ±9
2 - Find the function h(x) = f(x) - g(x) if f(x) = 3^x and g(x) = 3^2x - 3^x.
h( x) = 0
h( x) = -3 ^2x
h( x) = 3 ^x(2 - 3 ^x)
h( x) = 2(3 ^2x)
Answer:
Part 1)
A
Part 2)
C
Step-by-step explanation:
1)
We are given:
[tex]f(x)=5x+1\text{ and } g(x)=x^2-9[/tex]
And that:
[tex]h(x)=f(x)/g(x)[/tex]
And we want to now for which values of x is h(x) undefined.
So, by substitution:
[tex]\displaystyle h(x)=\frac{5x+1}{x^2-9}[/tex]
Remember that for rational functions, the function will be undefined if and only if the denominator is 0.
This is because we cannot divide by 0.
So, to find the values for which the denominator is 0, set the denominator to 0 and solve for x. Therefore:
[tex]x^2-9=0[/tex]
Add 9 to both sides:
[tex]x^2=9[/tex]
Take the square root of both sides. Since we are taking an even-root, we will need plus/minus. Therefore:
[tex]x=\pm 3[/tex]
So, h(x) is undefined for ±3.
Our answer is A.
2)
We are given:
[tex]f(x)=3^x\text{ and } g(x)=3^{2x}-3^x[/tex]
And we want to find:
[tex]h(x)\text{ if } h(x)=f(x)-g(x)[/tex]
So:
[tex]h(x)=3^x-(3^{2x}-3^x)[/tex]
Distribute:
[tex]h(x)=3^x-3^{2x}+3^x[/tex]
Combine like terms:
[tex]h(x)=2(3^x)-3^{2x}[/tex]
Rewrite:
[tex]h(x)=2(3^x)-(3^x)(3^x)[/tex]
Factor out:
[tex]h(x)=3^x(2-3^x)[/tex]
So, our answer is C.

Chris works at a jewelry store, and he earns 4% commission on all sales that he makes. If Chris's jewelry sales total $1,370, how much will he earn in commission?
Answer:
[tex]\boxed {\boxed {\sf \$54.80}}[/tex]
Step-by-step explanation:
Chris earns the commission on the jewelery sales. To calculate what he earned, multiply the commission rate and his sales.
[tex]commission= commission \ rate * sales[/tex]
His rate is 4% and his sales are $1,370
[tex]commission= 4\% * \$1370[/tex]
Convert the percent to a decimal. Divide by 100 or move the decimal two spots to the left.
4/100= 0.04 4.0 --> 0.4 --> 0.04[tex]commission= 0.04* $1370[/tex]
[tex]commission = \$ 54.8[/tex]
Chris's commission is $54.80
A 2-bedroom apartment that rents for $520 a month is $40 less than twice the cost of a 1-bedroom apartment. What is the monthly rent of a 1-bedroom apartment?
Answer:monthly rent of a 1-bedroom apartment= $280
Step-by-step explanation:
Let the cost of 1 bed room apartment = x
And the cost of two bedroom apartment= 2x-40
Since the cost of of two bedroom apartment = $520
Then the cost of one bed room part will be expressed as
520= 2x- 40
520+40 = 2x
560= 2x
x= 560/ 2
x= 280
Therefore the cost of 1 bed room apartment = x= $280

Scott is 72 inches tall and Chris is 185 centimeters tall how tall is Chris in inches?
Answer:
Around 72.8 inches
Step-by-step explanation:
We are given the infomation that Chris is 185 centimeters tall.
There are 2.54 centimeters in an inch.
185/2.54 = 72.8346 ≈ 72.8
Chris should be around 72.8 inches.
Hope this helps.
Chris should be around 72.8 inches tall.
Here, we have,
given that,
Scott is 72 inches tall and Chris is 185 centimeters tall
We are given the information that Chris is 185 centimeters tall.
now, we know that,
There are 2.54 centimeters in an inch.
Since 1 inch = 2.54 centimeters
all we need to do is to divide 185 by 2.54
i.e. 185/2.54 = 72.8346 ≈ 72.8
The answer will be 72.8.
Chris should be around 72.8 inches.

ABCD is a parallelogram.
AD = 12 cm.
DC = 9 cm.
The perpendicular distance of
from CD is 8 cm.
What is the perpendicular distance of AD from BC?
9514 1404 393
Answer:
6 cm
Step-by-step explanation:
The area of the parallelogram is the same, either way you figure it.
A = bh
A = CD(length ⊥ to CD)
A = (9 cm)(8 cm) = 72 cm²
__
A = AD(length ⊥ AD)
72 cm² = (12 cm)(length ⊥ AD)
(length ⊥ AD) = (72 cm²)/(12 cm) = 6 cm
The perpendicular distance of AD from BC is 6 cm.

Fill in the table using this function rule.
y=26-4x
The complets table of values for the function rule
x 1 2 4 6
y 22 18 10 2
Completing the table of values for the function ruleFrom the question, we have the following parameters that can be used in our computation:
y = 26 - 4x
The missing y values are at x = 1, 2, 4 and x = 6
Substitute the known values in the above equation, so, we have the following representation
y = 26 - 4(1) = 22
y = 26 - 4(2) = 18
y = 26 - 4(3) = 10
y = 26 - 4(6) = 2
So, the missing values are 22, 18. 10 and 2
