Step-by-step explanation:
Given the total pay for the week of X hours given by f(x)=100+14x, the domain of the function is the value of the input variable x for which the function exists. Since her to total week cannnot be negative, hence the value of x for which the function occurs is on all positive integers. This is represented according to the set notation;
Domain = [0, ∞)
The range of the function is the value of the output variable f(x) for all vaues of x for which the function occurs. Snce the minimum value of x is 0, the minimum value of the function will be at f(0);
f(0) = 100 + 14(0)
f(0) = 100 + 0
f(0) = 100
Hence the range of the function will be expressed as;
Range = [100, ∞)

In right triangle ABC, angle C is a righ angle, AB=13, and BC=5 .what is the length of AC?
Answer:
12
Step-by-step explanation:
Since this is a right triangle you can you pythagorean theorem.
a^2+b^2=c^2
A= shortest side.
B=middle side.
C=longest/slanted side or hypotenuse.
So AB is the hypotenuse.
BC is the short side.
this means that AC is the middle side. Plug your numbers in.
25 + b^2 =169
b^2=144
b=12
AC=12
Joseph is reading a 32 page book he read 6 pages in 15 minutes if he continues to read at the same rate how long will it take him to read the entire book
Answer:
80 minutesssssss
Answer:
(edit) your answer is 80 min
Step-by-step explanation:
first we can set this up as a proportion.
so it would be 15 over 6 and your other side would be x over 32
so when u cross multiple your equation would be 6x = 480
then you divide both sides by 6 and when you divide 480 by 6 u will get 80

Kate is organizing 585 video games into shipping boxes. Not all of the customers are ordering the same amount of videos, so not all of the boxes are going to be the same size. What are Kates options for the number of video games that can be put in each shipping box?
Answer:
1. So, Kate can put 45 video games each in 13 shipping boxes or 13 video games each in 45 shipping boxes.
2. Kate can put 117 video games each in 5 shipping boxes or 5 video games each in 117 shipping boxes.
3. Kate can put 9 video games each in 65 shipping boxes or 65 video games each in 9 shipping boxes.
Step-by-step explanation:
The prime factorization of 585 = 3² × 5 × 13.
So, the number of video games Kate can put in each shipping box are the different combinations of the prime factors. So, they are
1. 3² × 5 × 13 = 45 × 13 or 13 × 45.
So, Kate can put 45 video games each in 13 shipping boxes or 13 video games each in 45 shipping boxes.
2. 3² × 5 × 13 = 3² × 13 × 5 = 117 × 5 or 5 × 117
So, Kate can put 117 video games each in 5 shipping boxes or 5 video games each in 117 shipping boxes.
3. 3² × 5 × 13 = 3² × 13 × 5 = 9 × 65 or 65 × 9
So, Kate can put 9 video games each in 65 shipping boxes or 65 video games each in 9 shipping boxes.

Use a matrix equation to solve the system of linear equations. left brace Start 2 By 1 Matrix 1st Row 1st Column 2nd Row 1st Column EndMatrix x plus 2 y equals 8 nbsp 2 x plus 6 y equals 9 What is the inverse matrix?
Answer:
[tex]\left[\begin{array}{ccc}3&-1&\\-1&1/2\\\end{array}\right][/tex]
Step-by-step explanation:
The matrix system for the linear equations: x + 2y = 8, 2x + 6y = 9
[tex]\left[\begin{array}{ccc}1&2&\\2&6\\\end{array}\right] \left[\begin{array}{ccc}x\\y\end{array}\right] = \left[\begin{array}{ccc}8\\9\end{array}\right][/tex]
To get the coefficient of x and y, the inverse of the first matrix (let the first matrix be A) must be known.
[tex]A^{-1}[/tex] = (1 / determinant of A) x Adjoint of A
the determinant of A = (1 x 6) - (2 x 2) = 6 - 4 = 2
Adjoint of A = [tex]\left[\begin{array}{ccc}6&-2&\\-2&1\\\end{array}\right][/tex]
[tex]A^{-1}[/tex]= [tex]\frac{1}{2} \left[\begin{array}{ccc}6&-2\\-2&1\end{array}\right][/tex] = [tex]\left[\begin{array}{ccc}3&-1&\\-1&1/2\\\end{array}\right][/tex]

a candle is burning at a linear rate. The candle measures five inches two minutes after it was lit. It measures three inches eight minutes after it was lit. What was the original length of the candle?
Answer:
5 2/3 inches.
Step-by-step explanation:
8-2=6 minutes and 5-3=2 inches so it lost 2 inches in 6 minutes. This means it loses an inch every three minutes. Since we have to go back by 2 minutes we will have to figure out how much length we have to add to the candle to figure out how long it was originally by multiplying by 2/3 as 2 inches is 2/3 the required to remove an inch, so 1 inch * 2/3 = 2/3 of an inch. Add that to the length at two minutes and we have 5 2/3 inches as its original size.

If Gabe's Soccer Ball Company is able, due to competitive pressure, to charge $60 for a new soccer ball, while one soccer ball costs $28 to make, plus $15,000 per month in overhead costs (mostly Gabe's extravagant salary) find: a. The average cost c(x) of producing each soccer ball b. Algebraically find the number of soccer balls Gabe's company must produce per month in order to break even (Profit = 0). Profit = Total Revenue – Total Cost c. Algebraically find the number of soccer balls Gabe's company must make to earn a profit of $10,000 per month. d. If Gabe took a pay cut to reduce the overhead costs to $8,000 per month, how many fewer balls would the company have to sell to break even. (There are multiple ways to get this result).
Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
Selling price= $60
Unitary variable cost= $28
Fixed costs= $15,000
First, we need to calculate the average total cost:
Average cost= total cost / number of units
For example, for 1 unit and 10,000 units:
1 unit:
Average cost= 15,028/1 = 15,028
10,000 units:
Average cost= (15,000 + 28*10,000) / 10,000
Average cost= $29.5
Now, we can calculate the break-even point in units:
0= (60*x) - (28*x) - 15,000
x= number of units to break-even
0= 32x - 15,000
15,000/32= x
468.75=x
break-even point in units= 469
For the desired profit of $10,000:
10,000 = (60*x) - (28*x) - 15,000
25,000= 32x
781.25= x
Break-even point= 782 units
Finally, fixed costs dropped by $8,000:
0= 32x - 7,000
x= 7,000/32
x= 218.75
Break-even point= 219
Difference= 250 units

when adjusted to solve for the answer is
[tex]c = \sqrt{a^{2}+b^{2}\\}[/tex]

A line that contains the point (0,4) if the slope of the line is m=5 write the equation of the line using slope intercept form
Answer:
y = 5x + 4
Step-by-step explanation:
Slope intercept form is y = mx + b. m is the slope which is already given to you, which leaves you with y = 5x + b. Then you plug in (0,4) to find what b is. 4 = 5(0) + b
4 = 0 + b
4 = b
y = 5x + 4

Answer:
[tex]-\frac{2}{3}[/tex]
Step-by-step explanation:
We can use the rise over run method to do this question.
Let's start at the coordinates (1,1)
If we go down 2 from that point and to the right 3 times then we see another point on the line (3, -1).
We would express this as 2 over 3 or [tex]\frac{2}{3}[/tex].
We aren't done yet however.
The line is sloping downwards and this means that the slope is negative.
So, the final answer is [tex]-\frac{2}{3}[/tex]
I hope this helps!!

What is the equation of the line through the points (3, 2), (8, 5), (13, 8) and (18, 11)?
A. y= 5/3x- 1/3
B. y= 3/5x- 1/5
C. y= 5/3x+ 1/3
D. y= 3/5x+ 1/5
Answer:
Option D.) y = 3/5 + 1/5
Step-by-step explanation:
First, we find the Slope using the formula: m = y2 - y1/x2 - x1
You may choose any two points but I will use these two for no reason at all.)
Points: (3,2) and (8,5)
m = y2 - y1/x2 - x1
m = 5 - 2/8 - 3
m = 3/5
Now that we have the slope, we can now find the Slope Intercept Form by using the Slope Form Formula. (need at least one point and slope.)
Formula: y - y1 = m(x - x1)
Point: (3,2) (you may choose any point but I will choose this for no reason at all xD)
y - y1 = m(x - x1)
y - 2 = 3/5(x - 3)
y - 2 = 3/5x - 9/5
y - 2 = 3/5x - 9/5
y = 3/5x - 9/5 + 10/5 (2 can be is any fraction that consists of the numerator multiplied twice by the denominator, such as 2/1, 4/2, 8/4, etc.)
y = 3/5 + 1/5
The final equation of the line can be written as -
y = (3/5)x + 1/5
What is the general equation of a straight line?
The general equation of a straight line is given by -
y = mx + c
Given is a line that passes through the points (3, 2), (8, 5), (13, 8) and (18, 11).
The line passes through the points (3, 2) and (8, 5). Therefore, the slope of the line will be -
m = (5 - 2)/(8 - 3) = 3/5
Now, consider the line : y = mx + c. For a point (3, 2) -
2 = (3/5) x 3 + c
2 = 9/5 + c
c = 2 - 1.8
c = 0.2
c = 1/5
Therefore, the final equation of the line can be written as -
y = (3/5)x + 1/5
