Use the Pythagorean theorem to determine the unknown length of the right triangle Determine the length of side c in each of the triangles that followers Do not include any units in your answer

Recall the Pythagorean Theorem:
For a right triangle with legs of lengths A and B and hypotenuse C, the following relation is satisfied:
[tex]A^2+B^2=C^2[/tex]If two variables are known (it could be the hypotenuse and one leg, or both legs), then the third can be calculated. If the hypotenuse is not known, it can be calculated as:
[tex]C=\sqrt[]{A^2+B^2}[/tex]If one of the legs is not known, then we can substract the other length squared, and then take the square root:
[tex]\begin{gathered} A^2=C^2-B^2 \\ \Rightarrow A=\sqrt[]{C^2-B^2} \end{gathered}[/tex]For problems involving the Pythagorean Theorem, use these equations by replacing the corresponding numerical values of A, B or C. Remember that C does not always stand for the hypotenuse, it always depend on the diagram. For example, if the legs of the right triangle were labelled as X and Y, and the hypotenuse was A, then:

The data set shown below represents the time in minutes spent using a computer at Kinko's copy center by 25 people on a randomly selected day construct a stem and leaf plot for the data and analyze the results 16, 25, 18, 39, 25, 17, 29, 14, 37 22, 18, 12, 23, 32, 35, 24, 26 20, 19, 25, 26, 38, 38, 33, 29
Answers
areTo produce a stem and leaf plot, we should follow these steps:
Step 1- Rearrange the numbers in ascending or descending order: This will make the plotting of the stem and leaf plot a lot easier.
Step 2- Next, we select the stems from each number in the data. the stem is the first digit in the number in consideration. For example, the stem of 16 is 1 because it is the first digit. We do this selection of stems for all the numbers in the dataset.
Step 3- Next, we select the leaves. The leaves are the digits that come after the stem in a number. For example, in the number 16, while 1 is the stem, 6 is the leaf of the number.
Step 4- We arrange the stems and leaves in a table and this represents the stem and leaf plot.
With this information, we can proceed to solve the question
Solution
Step 1:
Rearranging the numbers, we have:
12, 14, 16, 17, 18, 18, 19, 20, 22, 23, 24, 25, 25, 25, 26, 26, 29, 29, 32, 33, 35, 37, 38, 38, 39
Step 2:
The stems of this data are just the first digit of each number.
12, 14, 16, 17, 18, 18, 19 all have a stem of 1
20, 22, 23, 24, 25, 25, 25, 26, 26, 29, 29 all have a stem of 2
32, 33, 35, 37, 38, 38, 39 all have a stem of 3.
Thus, the stems of this data are: 1, 2, and 3.
Step 3:
The leaves of the data are the second digits of the numbers. Thus, we have that
The leaves of these numbers 12, 14, 16, 17, 18, 18, 19 are: 2, 4, 6, 7, 8, 8, 9.
The leaves of these numbers 20, 22, 23, 24, 25, 25, 25, 26, 26, 29, 29 are: 0, 2, 3, 4, 5, 5, 6, 6, 9, 9
The leaves of these numbers 32, 33, 35, 37, 38, 38, 39 are: 2, 3, 5, 7, 8, 8, 9.
Step 4:
Thus, we can proceed to generate the leaf plot as follows:

The x-intercept and y-intercept are (-12,0) and (0,-8) for the equations is 2x+3y=-24.
Given that,
The equation of 2x+3y=-24
We must determine the equation's x-intercept and y-intercept.
In the cartesian coordinate system, the horizontal X-axis and the vertical 'Y-axis' are two perpendicular axes that make up the coordinate plane. The line's intercepts—where it crosses the two axes are referred to as.
We have to find x-intercept.
To find x-intercept take the y value as zero.
2x+3y=-24
2x+3(0)=-24
2x=-24
x=-24/2
x=-12
Now, To find y-intercept take x value as zero.
2x+3y=-24
2(0)+3y=-24
3y=-24
y=-24/3
y=-8
Therefore, The x-intercept and y-intercept are (-12,0) and (0,-8) for the equations is 2x+3y=-24.

Answers
The mathematical model that estimates the average cost of tuition and fees, T, at public 4 years college for the school year ending x years after 2000 is T = 3349 + 379x.
We can use the data in Figure from 2000 and 2016 to estimate the
yearly increase in tuition and fees.
Yearly increase in tuition and fees is approximately = change in tuition and fees from 2000 to 2016 / change in time from 2000 to 2016
⇒ ≈ 9410 - 3349 / 2016 - 2000
⇒ 6061/16
= 378.8125
= 379
Each year the average cost of tuition and fees for public four-year
colleges is increasing by approximately $379.
Now we can use variables to obtain a mathematical model that estimates the average cost of tuition and fees, T, for the school year ending x years after 2000.
⇒ The average cost of tuition and fees is:
⇒ T = 3349 + 379x
The mathematical model T = 3349 + 379x estimates the average cost
of tuition and fees, T, at public four-year colleges for the school year
ending x years after 2000.
Hence we get the mathematical model as T = 3349 + 379x

First, let's find the volume of the truncated cone using the following equation
[tex]V=\frac{1}{3}\pi h(r^2+rR+R^2)[/tex]Where h is the height of the cone, r is the smallest radio and R is the largest radio. So, replacing h = 4 ft, r = 1.5 ft and R = 4.5 ft, we get:
[tex]\begin{gathered} V=\frac{1}{3}(3.14)(4)((1.5)^2+(1.5)(4.5)+(4.5)^2) \\ V=\frac{1}{3}(3.14)(4)(29.25) \\ V=122.52ft^3 \end{gathered}[/tex]Because the radius is half the diameter, so r = 3ft/2 = 1.5 ft and R = 9ft/2 = 4.5 ft.
Now, we know the volume in cubic feet. To find the volume in bushels, we will use the conversion factor 1 ft³ = 1.24 bushels.
[tex]122.52ft^3\times\frac{1.24\text{ bushels}}{1ft^3}=151.93\text{ bushels}[/tex]Therefore, the answer is 151.93 bushels

identify the place occupied by the digit 9. 1,664,963
Answers
Let us define place value
Place value is the value of each digit in a number. For example, the 5 in 350 represents 5 tens, or 50; however, the 5 in 5,006 represents 5 thousands, or 5,000. It is important that we understand that whilst a digit can be the same, its value depends on where it is in the number.
Given the number 1,664,963, the place values of each of the numbers are
1= 1 Million
the first 6 from the left= 6 hundred thousands
the second 6 from the left = 6 ten thousands
4= 4 thousands
9= 9 hundreds
the last 6 from the left = 6 tens, and
3= 3 units
Hence, the place occupied by 9 in the number 1,666,963 is 9 hundreds
