We can see that linear function B has a greater rate of change than function A.
Which function has the greater rate of change?The general linear function is written as:
y = a*x +b
Where a is the rate of change.
If we know two points on the linear function, (x₁,y₁) and (x₂, y₂), then the rate of change is given by:
a = (y₂ -y₁)/(x₂ - x₁)
For function A we use the first two on the table (1, 5) and (2, 7)
a = (7 - 5)/(2 - 1) = 2
For the function B we willuse (1, 1) and (2, 4), then:
a = (4 - 1)/(2 - 1) = 3
Function B has a greater rate of change.

Carmen is planning rail lines for a new train station. Help her find m z1. Explain how you found that solution.
In summary, to find m z1, we need to know the relationship between the rail lines and the angles formed by their intersection.
What is equation?An equation is a mathematical statement that shows the equality of two expressions. It is composed of two sides, separated by an equals sign (=), indicating that the two sides are equivalent in value. An equation may contain variables, which are unknown values represented by letters, as well as constants, which are known values. Equations are used in many areas of mathematics and science to model and solve problems. For example, the equation y = mx + b is a linear equation that describes the relationship between the variables x and y in a straight line, where m is the slope of the line and b is the y-intercept. Equations can be solved by manipulating the variables and using mathematical operations to isolate the unknown value.
Here,
In order to help Carmen find m z1, we need some additional information about the rail lines and the angles involved.
Assuming that z1 is an angle formed by the intersection of two rail lines, we can use the following steps to find its measure:
Identify the other angles formed by the two rail lines. If the rail lines are perpendicular, then z1 is a right angle and has a measure of 90 degrees. If the rail lines are not perpendicular, then they form two pairs of opposite angles, each with a measure of x degrees.
Use the fact that the sum of the measures of all angles formed by the intersection of two rail lines is 360 degrees. This means that the sum of the measures of the two pairs of opposite angles is 360 degrees.
Solve for x by setting the sum of the measures of the two pairs of opposite angles equal to 360 degrees and then solving for x. Once you have x, you can find the measure of any of the angles formed by the intersection of the rail lines, including z1.
For example, let's say that the two rail lines form two pairs of opposite angles, each with a measure of x degrees. Then, we have:
2x + 2z1 = 360 (since the sum of the measures of all angles formed by the intersection of two rail lines is 360 degrees)
Simplifying this equation, we get:
2z1 = 360 - 2x
z1 = (360 - 2x)/2
Now we need more information to find x, such as the measure of one of the opposite angles or the relationship between x and another angle in the figure. Once we know x, we can substitute it into the equation for z1 to find its measure.

What is the missing measure of the missing angle 59 86?
The missing measure of the angle on the triangle will be 45°.
How to calculate the angleAn angle is the measure of the space between two intersecting lines or planes. It is usually measured in degrees or radians. A degree is a unit of measurement for angles, where a full circle is 360 degrees, while a radian is a unit of measurement for angles defined as the angle subtended at the center of a circle by an arc equal in length to the radius of the circle.
Angles can be acute (less than 90 degrees), right (exactly 90 degrees), obtuse (more than 90 degrees and less than 180 degrees), or straight (exactly 180 degrees).
The missing angle will be:
= 180° - (76° + 59°)

Shape P could have been transformed using a translation, rotation, reflection or a combination of these transformations.
What is tranformations?Transformation in maths is a way of changing the position, size or shape of a given object. It involves moving the object from one position to another. This can be done using a combination of translation, rotation, reflection and enlargement.
A translation is when a shape is moved in a straight line and all points are moved the same distance in the same direction. A rotation is when a shape is rotated around a fixed point and all points are moved the same angle. A reflection is when a shape is flipped over a line and all points are reversed on the other side of the line.
In the case of Shape P, since one point was invariant, the transformation must have been either a translation, rotation or a combination of both. A translation would have been impossible as all points are moved the same amount and direction, hence, the invariant point would have been moved. A rotation is possible as all points are moved the same angle, and the angle of rotation could be adjusted to keep the invariant point in the same place. A combination of both of these transformations could also have been used to keep one point invariant.
Overall, Shape P could have been transformed using a translation, rotation, reflection or a combination of these transformations. In this case, the transformation must have been either rotation or a combination of both translation and rotation. The angle of rotation or the combination of translation and rotation would have been adjusted to keep the invariant point in the same place.

Question
The average daily balance of a credit card for the month of December was $5600, and the unpaid balance at the end of the
month was $6900. If the monthly interest rate is 2.5% of the average daily balance, what is the total balance on the next
billing date January 1? Round your answer to the nearest cent. Do not use commas to separate numbers or dollar signs. For
example, $5, 678.00 should be entered as 5678.00.
Answer:
The first step is to determine the amount of interest charged for the month of December based on the average daily balance:
Average Daily Balance = $5600
Monthly Interest Rate = 2.5%
Interest Charged for December = Average Daily Balance * Monthly Interest Rate * Number of Days in December
Number of days in December is 31.
Interest Charged for December = $5600 * 0.025 * 31 = $4340.00
The total balance on the credit card on January 1 will be the sum of the unpaid balance at the end of December and the interest charged for December:
Total Balance on January 1 = Unpaid Balance at End of December + Interest Charged for December
Total Balance on January 1 = $6900 + $4340.00
Total Balance on January 1 = $11240.00
Rounded to the nearest cent, the total balance on the next billing date January 1 is $11,240.00.
The nearest cent, the total balance on the next billing date, January 1, is $12640.00.
To calculate the total balance on the next billing date, we need to consider the average daily balance for December, the unpaid balance at the end of December, and the monthly interest rate.
The monthly interest rate is 2.5% of the average daily balance. Let's calculate the interest charged for the month of December:
Interest charged = (2.5/100) * Average daily balance
= (2.5/100) * $5600
= $140
Next, let's calculate the total balance on the next billing date, January 1:
Total balance = Average daily balance + Interest charged + Unpaid balance
= $5600 + $140 + $6900
= $12640
Rounded to the nearest cent, the total balance on the next billing date, January 1, is $12640.00.

The Director of Nursing (DON) in a long-term care facility receives a gross yearly salary of $67,000. The DON is married with three dependents and has enrolled in the company's insurance family plan. The long-term care facility employees receive paychecks every other week. a. Calculate the gross salary per pay period. b. Compute the net salary per pay period.
a. To calculate the gross salary per pay period, we need to divide the yearly salary by the number of pay periods in a year:
Gross salary per pay period = Yearly salary / Number of pay periods per year
Since there are 26 pay periods in a year (bi-weekly paychecks), we have:
Gross salary per pay period = $67,000 / 26 = $2,576.92
Therefore, the DON's gross salary per pay period is $2,576.92.
b. To compute the net salary per pay period, we need to take into account federal and state taxes, Social Security, and Medicare deductions, as well as any other pre-tax or post-tax deductions, such as health insurance premiums or retirement contributions.
Assuming a standard tax withholding rate of 20%, Social Security and Medicare deductions of 7.65%, and health insurance premiums of $200 per pay period, we can calculate the net salary per pay period as follows:
Net salary per pay period = Gross salary per pay period - Taxes - Social Security and Medicare - Health insurance
Net salary per pay period = $2,576.92 - ($2,576.92 x 0.20) - ($2,576.92 x 0.0765) - $200
Net salary per pay period = $2,576.92 - $515.38 - $197.02 - $200
Net salary per pay period = $1,664.52
Therefore, the DON's net salary per pay period is $1,664.52.

[tex]\stackrel{mixed}{1\frac{1}{2}}\implies \cfrac{1\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{3}{2}}~\hfill \stackrel{mixed}{2\frac{1}{4}} \implies \cfrac{2\cdot 4+1}{4} \implies \stackrel{improper}{\cfrac{9}{4}} \\\\[-0.35em] ~\dotfill[/tex]
[tex]\begin{array}{ccll} miles&minutes\\ \cline{1-2} \frac{3}{2}&\frac{9}{4}\\[1em] x&34 \end{array}\implies \cfrac{~~ \frac{3 }{2 } ~~}{x}~~ = ~~\cfrac{~~ \frac{9}{ 4} ~~}{34}\implies \cfrac{3}{2x}=\cfrac{9}{(4)(34)}\implies \cfrac{3}{2x}=\cfrac{9}{136} \\\\\\ (3)(136)=18x\implies \cfrac{(3)(136)}{18}=x\implies \cfrac{68}{3}\implies \stackrel{ miles }{x=22\frac{2}{3}}[/tex]
Step-by-step explanation:
11/2 is equivalent to 21/4 is
equivalent to 9/4
The unit rate will be:
3/2 miles= x
9/4 min 1 min
Now use this unit to find how far the car will travel in 26 minutes
2/3 mile •26 min= 52/3 miles or 17 and 1/3
miles
1 min
Since 1 hour is equal to 60 minutes, we can
multiply the unit rate by 60 to find the distance traveled in 1 hour.
2/3 mile• 60 min = 120/3 = 40 miles
traveled in 1 hour
1 min
