A business started the year with a net worth of $4,873. During the first six months of the year, the business
recovered and increased its net worth to a value of $15,866. Find the average monthly increase in net worth for the 6-month period.
The average monthly increase in net worth for the 6-month period is $1832.16.
Given:
A business started the year with a net worth of $4,873. During the first six months of the year, the business recovered and increased its net worth to a value of $15,866.
Six months net worth = 15,866 - 4873
= 10,993
Average monthly increase in net worth = six month net worth / 6
= 10,993/6
= $1832.16.
Therefore The average monthly increase in net worth for the 6-month period is $1832.16.

Oliver borrowed $1,500 to purchase a riding lawn mower for his lawn care business. The bank offered him an interest rate of 12% for 6 months. Calculate the simple interest using I = prt. $69 $90 $420 $1,080
The simple interest that Oliver needs to pay is $ 90
Calculating Simple interest:Simple interest is nothing but interest on a loan at a rate. The formula for Simple interest is given below
Simple interest, I = ptr
where p = principal amount
t = time period in years
r = rate of interest in decimals
Here we have
Oliver borrowed $1,500 to purchase a riding lawn mower
The rate of interest r = 12%
=> 12/100 = 0.12 (in decimals )
The time period given = 6 months = 0.5 years [ 6/12 = 0.5 ]
From the above formula,
The simple interest, I = ptr
=> I = $1,500(0.12) (0.5) = $ 90
Therefore,
The simple interest that Oliver needs to pay is $ 90

Suppose that 12 inches of wire cost 48 cents at the same rate how many inches of wire can be bought for 28 cents
Answer:
7 in
Step-by-step explanation:
If 12 inches of wire can be bought for $0.48, we can set up the following ratio:
[tex]\frac{12\text{ in}}{\$0.48}[/tex]
Then, to determine how many inches of wire can be bought for $0.28, set up equivalent fractions, as such:
[tex]\frac{12\text{ in}}{\$0.48}=\frac{x}{\$0.28}[/tex]
Then, cross-multiply and solve for [tex]x[/tex]:
[tex]\$0.48x=(\$0.28)(12)[/tex]
[tex]\$0.48x=\$3.36[/tex]
[tex]x=\frac{\$3.36}{\$0.48}[/tex]

Which function is the inverse of f(x) = -5x—4
Answer: f^-1(x)= - 1/5x - 4/5
Step-by-step explanation:
substitute y for f(x): y= -5x-4
interchange x and y: x=-5y-4
swap the sides: -5y-4=x
move the constant -5y=x+4
divide both sides by 5 y= - 1/5x - 4/5
substitute f^-1(x) for y f^-1(x)= - 1/5x - 4/5
determine the interval(s) for which the function shown below is decreasing
Answer:
(∞,-3) and (1,-∞)
Step-by-step explanation:
Decreasing means going down or in math terms, going toward the negatives.
When you are talking intervals in math, you only want to use the x-axis for the interval points. We write the interval as if it was a coordinate point though.
Looking at the graph it looks like it is going from infinity to -3 or written as (∞,3) and from 1 to negative infinity or written as (1, -∞)
The interval(s) for which the function shown below is decreasing are (∞,-3) and (1,-∞).
What is a function?A function is a relationship between two sets of values in mathematics where each input value (or "argument") corresponds to a certain output value.
In most cases, the input values come from a set referred to as the function's domain, while the output values come from a set referred to as the function's range.
Declining is the mathematical phrase for decreasing or moving towards the negatives.
Mathematicians only use the x-axis to represent interval points when discussing intervals. Yet, we express the interval as if it were a coordinate point.
If you look at the graph, it appears to be traveling from infinity to -3, which is written as (,3), and from one to negative infinity, which is written as (1, -).

An equation modeling the population, p, of Ohio given the year, t is,
p = 0.04t + 10.98.
What is population?
The term "population" refers to all citizens who are either permanently residing in a country or who are just passing through. This indicator reveals how many people typically reside in a certain area. Growth rates are the population changes that occur each year as a result of births, deaths, and net migration.
Given: In the year 2000, the population of Ohio was 11.03 million people. By the year 2017 the population of Ohio was 11.66 million people.
From this we get, two points (0, 11.03) and (17, 11.66).
First to find the slope using the above two points.
[tex]m=\frac{11.66 - 11.03}{17-0} = \frac{0.63}{17} = 0.04[/tex]
Now to find the equation,
Consider,
p - 11.66 = 0.04(t - 17)
p - 11.66 = 0.04t - 0.68
p = 0.04t - 0.68 + 11.66
p = 0.04t + 10.98
Therefore, the equation modeling the population, p, of Ohio given the year, t is, p = 0.04t + 10.98

The revenue function is given by R(x)=x⋅p(x) dollars where x is the number of units sold and p(x) is the unit price. If p(x)=26(4)−x5, find the revenue if 15 units are sold. Round to two decimal places.
If price p(x) =26(4)^{-x/5}, the revenue when 15 units are sold is equal to $6.09.
How to calculate the amount of revenue at p(15)?From the information provided, the amount of revenue with respect to price that's being generated in this scenario can be calculated by using the following function (expression):
R(x) = x × P(x)
Where:
x represents the number of units sold.p(x) represents the unit price.Since the revenue function, we would simply substitute the value of the unit price and evaluate as follows:
Revenue, R(x) = x × 26(4)^{-x/5}
Substituting the given parameters into the formula, we have;
Revenue, R(x) = 15 × 26(4)^{-15/5}
Revenue, R(x) = 15 × 26(4)^{-3} or (15 × 26)/4³
Revenue, R(x) = 15 × 26(0.015625) or 390/64
Revenue, R(x) = 6.09375 ≈ $6.09.

A teacher bought markers at a cost of $3 per set. The teacher had a $2-off coupon to use
toward the total cost of the markers bought.
Which table shows the relationship between , the number of sets of markers bought by the
teacher, and y, the total cost of the markers?
The first table A shows the relationship between the number of sets of markers bought by the teacher and the total cost of the markers.
From given question, the cost per set of markers = $3
The teacher had a $2-off coupon to use toward the total cost of the markers bought.
It is given that the number of sets of markers bought by the teacher is x, and y is the total cost of the markers.
so, we get a linear equation as:
3x - 2 = y
From table A we can see that the data satisfied the given equation,
3x - 2 = y
when x = 3, y = 3(3) - 2 = $7
when x = 9, y = 3(9) - 2 = $25
when x = 12, y = 3(12) - 2 = $34
when x = 24, y = 3(24) - 2 = $70
Therefore, the first table A shows the relationship between the number of sets of markers bought by the teacher and the total cost of the markers.

The slope of the line that is parallel to the line -7x-5y=-6 is -7/5
What is the slope of a line?It is possible to determine a line's direction and steepness by looking at its slope. Finding the slope of lines in a coordinate plane can aid in anticipating whether the lines are parallel, perpendicular, or none at all without actually using a compass.
Any two unique places along the line may be used to determine the slope of any line. When two different places on a line are considered, the slope of a line formula compares the vertical change to the horizontal change in each case. We shall comprehend how to discover the slope in this piece, along with some of its uses.
Given, line is -7x-5y=-6
We have to write the given line in slope-intercept form
Then, y= (-7/5)x+(6/5)
The slope-intercept form is y= mx +c
By using the slope-intercept form,
Slope=(-7/5)
The lines that are parallel to y= (-7/5)x+(6/5) have the same slope of -7/5
Therefore, the slope of the line that is parallel to the line -7x-5y=-6 is -7/5

The slope of the line x = 3 is undefined
How to describe the slope of the line
The slope is defined as the ratio of the vertical change between two points, the rise, to the horizontal change between the same two points, the run.
Mathematically, the slope is the change in y divided by the change in x. That is:
Slope = y2-y1 / x2-x1
Let's pick any two convenient points on the line:
(3, 9) and (3, -9) = > x1 = 3, y1 = -9 and x2 = 3, y2 = 9
Slope = 9-(-9) / 3-3 = 18/0
The denominator here is 0, if you evaluate this using a calculator you will a maths error. So we say the slope is undefined
Notice that: There is no change in x i.e. x1 = x2
Therefore, the slope of x = 3 is undefined because x = 3 is a vertical line

Usando la relacion:
tan(a) = (cateto opuesto)/(cateto adjacente)
