Given is a Right triangle PQR with angle Q = 90 degrees.
Given are sides PQ = 8 cm, QR = 15 cm, PR = 17 cm.
Side PR is the hypotenuse.
We can use formula for "sin" given as follows :-
[tex] sin(\theta)=\frac{Opposite}{Hypotenuse} [/tex]
For angle R, opposite side would be PQ.
[tex] sin(R)=\frac{PQ}{PR} \\\\
sin(R)=\frac{8}{17} \\\\
sin(R)=0.470588235 \\\\
R=sin^{-1}(0.470588235) \\\\
R = 28.07248694 \;\;degrees \approx 28.07 \;degrees [/tex]
For angle P, opposite side would be QR.
[tex] sin(P)=\frac{QR}{PR} \\\\
sin(P)=\frac{15}{17} \\\\
sin(P)=0.882352941 \\\\
P=sin^{-1}(0.882352941) \\\\
P = 61.92751306 \;\;degrees \approx 61.93 \;degrees [/tex]
Hence, R = 28.07 degrees and P = 61.93 degrees.
To solve the problem we must know about Trigonometric functions.

[tex]\rm {Cos \theta=\dfrac{Base}{Hypotenuse}[/tex]
[tex]\rm {tan\theta=\dfrac{Perpendicular}{Base}[/tex]
where perpendicular is the side of the triangle which is opposite to the angle, and the hypotenuse is the longest side of the triangle which is opposite to the 90° angle.

The length of a rectangle is 3 times its width. if the width is diminished by 1 inch and the length is increased by 3 inches. the area of the the new rectangle is 72 square inches. find the dimensions of the original rectangle.
The width of the original rectangle is 5 inches and the length is 15 inches.
Explanation:Let's assume the width of the original rectangle is x inches. According to the problem, the length of the rectangle is 3 times its width, so the length of the original rectangle is 3x inches.
When the width is diminished by 1 inch, the new width becomes x - 1 inches. And when the length is increased by 3 inches, the new length becomes 3x + 3 inches.
The area of a rectangle is given by length multiplied by width, so we can set up the following equation:
(x - 1)(3x + 3) = 72
By multiplying out the terms and rearranging the equation, we get:
3x^2 + 6x - x - 3 = 72
Combining like terms and simplifying further:
3x^2 + 5x - 75 = 0
Solving this quadratic equation gives us two possible answers for x: x = -5 or x = 5.
Since the width cannot be negative, we discard the negative value of x. Therefore, the width of the original rectangle is 5 inches and the length is 3 times the width, which is 3 * 5 = 15 inches.

Which of the following functions best represents the graph?
A. f(x) = x3 + 2x2 − 4x − 8
B. f(x) = x3 + 4x2 − x − 4
C. f(x) = x3 + x2 − 9x − 9
D. f(x) = x3 + 3x2 − 3x − 9
Answer:
Option: C is the correct answer.
[tex]f(x)=x^3+x^2-9x-9[/tex]
Step-by-step explanation:
Clearly from the graph we could see that:
3 and -3 are zeros of the function f(x).
since the graph crosses these two points on the x-axis.
i.e. when x=3 or -3 ⇒ f(x)=0
Now when we put x=3 in each of the equation we see that:
A)
[tex]f(x)=x^3+2x^2-4x-8[/tex]
when x=3
[tex]f(x)=3^3+2\times 3^2-4\times 3-8\\\\f(x)=27+18-12-8\\\\f(x)=25\neq0[/tex]
Hence, option A is incorrect.
B)
[tex]f(x)=x^3+4x^2-x-4[/tex]
when x=3
[tex]f(x)=27+36-3-4\\\\f(x)=56\neq0[/tex]
Hence, option B is incorrect.
D)
[tex]f(x)=x^3+3x^2-3x-9[/tex]
when x=3
[tex]f(x)=27+27-9-9\\\\f(x)=36\neq0[/tex]
Hence, option D is incorrect.
Hence all the three options are discarded.
Hence, option C is the correct answer.
The function best represents the graph is:

The wheels on Annie's bicycle are $20$ inches in diameter. If each wheel makes $3$ full revolutions every second, then how many feet does Annie travel in $1$ second? Give your answer as an integer, rounded to the nearest foot.
Final answer:
To calculate the distance Annie travels on a bicycle with 20-inch diameter wheels making 3 revolutions per second, use the formula for calculating distance traveled.
Explanation:
The diameter of the wheels is 20 inches, which means the radius is half of the diameter, so radius = 10 inches = 10/12 feet. Each wheel makes 3 revolutions per second.
To find how many feet Annie travels in 1 second, you can use the formula:
Distance traveled = 2 * pi * radius * number of revolutions per second.
Substitute the values into the formula and then round to the nearest foot to get the answer.
The answer is 0 feet.

shape @NeedHelpQuick546 @paki @texaschic101 @mjoxprm360,
The measure of variation for a numerical data set describes how the values of a number vary with the single number. This measurement shows the difference in the properties of a certain number to the rest of the numbers in the numerical data set.
The term that describes how values of a numerical data set vary with a single number is 'variation'. It quantifies the spread of data values, helping to add context and meaning to averages in a data set.
Explanation:A measure of variation for a numerical data set describes how its values vary with a single number. Variation is a statistical concept that is used to quantify the spread or dispersion of a set of data values. A low variation indicates that the data points tend to be close to the mean (or expected value), while a high variation indicates that the data points are spread out over a wider range.
For example, if we have a data set of test scores, the variation can help us understand how close or far the scores are from the average test score. This provides more context and meaning to the overall average.

Find the lateral area of a right circular cone whose radius is 6 feet and height is 8 feet.
The lateral area of a right circular cone with a radius of 6 feet and height of 8 feet is 60π square feet. We calculate this by first finding the slant height using the Pythagorean Theorem and then substituting the radius and slant height into the formula for the lateral area of a cone.
Explanation:The lateral area of a cone can be calculated using the formula πrl, where r is the radius and l is the slant height. However, in this question, we're not provided the slant height, but the height. Therefore, we first need to find the slant height using the Pythagorean theorem, since a right circular cone forms a right triangle with the radius and the height. Using Pythagorean theorem, the slant height (l) can be found as
l = √(r² + h²) = √((6ft)² + (8ft)²) = 10ft.
Substitute the values of r and l into the formula for lateral area: πrl = π × 6ft × 10ft = 60π ft².
So, the lateral area of the cone is 60π square feet.

Jordan is a manager of a car dealership. He has two professional car washers, Matthew and Arianna, to clean the entire lot of cars. Matthew can wash all the cars in 14 hours. Arianna can wash all the cars in 11 hours. Jordan wants to know how long it will take them to wash all the cars in the lot if they work together.
Write an equation and solve for the time it will take Matthew and Arianna to wash all the cars together. Explain each step.
Answer:
They will take 6.16 hrs or 6 hrs, 9 minutes and 36 seconds.
Step-by-step explanation:
Consider the provided information.
Let x is the number of cars in a lot.
Matthew can wash all the cars in 14 hours. That means in 1 hr he can wash x/14 cars.
Arianna can wash all the cars in 11 hours. That means in 1 hr Aranna can wash x/11 cars.
Together there rate will be:
[tex]\frac{x}{14}+\frac{x}{11}=\frac{x}{y}[/tex]
Here y represent the time taken by them if they work together.
Divide both sides by x, we get
[tex]\frac{1}{14}+\frac{1}{11}=\frac{1}{y}[/tex]
Thus, the required equation is: [tex]\frac{1}{14}+\frac{1}{11}=\frac{1}{y}[/tex]
Now solve for time, Here time is represents by y.
[tex]\frac{1}{14}+\frac{1}{11}=\frac{1}{y}[/tex]
[tex]\frac{11+14}{154}=\frac{1}{y}[/tex]
[tex]\frac{25}{154}=\frac{1}{y}[/tex]
[tex]y=\frac{154}{25}[/tex]
[tex]y=6.16[/tex]
Hence, they will take 6.16 hrs or 6 hrs, 9 minutes and 36 seconds.
