Answer:
45º and -1.
Step-by-step explanation:
The angle is\($\theta = \frac{7 \pi}{4} $\) given in radians, but you want the angle in degrees.
\($\frac{7 \pi}{4} \cdot \frac{180}{\pi} = \frac{1260}{4} = 315\º$\)
We got a Quadrant IV Angle.
Once the reference angle is the smallest angle that the terminal side of a given angle makes with the x-axis, we are talking about the angle \(45\º\).
Therefore, the reference angle is \(45\º\).
Also, the tangent of \($\theta = \frac{7 \pi}{4} $\) is -1

First we start with the formula for cylinders v=(pi)r(squared)h filled in Thats v=(3.14)(8 squared) (8) which brings us to the answer 1607.68 but you must round to the nearest tenth aka 1607.7
Answer:
The first option, V ≈ 1607.7 in²
Step-by-step explanation:
Find the volume of the given cylinder.
\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)
Given:
r = 8 in
h = 8 in
π = 3.14
Find:
V = ?? in³
\(\hrulefill\)
Now solving,
Substitute the given values into the formula:
=> V = (3.14)(8)²(8)
Using a calculator to simplify:
=> V = 1607.68 in²
Rounded to the nearest tenth:
∴ V ≈ 1607.7 in²
Thus, the first option is correct.
Which graph represents the function y = x – 2? A coordinate plane with a line passing through (0, negative 3) and (2, 0). A coordinate plane with a line passing through (0, 2) and (2, negative 1). A coordinate plane with a line passing through (0, negative 2) and (3, 0). A coordinate plane with a line passing through (0, 1.5) and about (2.25, 0).
Answers
The graph that represents y = x - 2 is a coordinate plane with a line passing through (0, -2) and (2, 0).
None of the given options is correct
The given equation is:
y = x - 2
Find the x-intercept by making y = 0 and finding the corresponding x-value
y = x - 2
0 = x - 2
x = 2
The line y = x - 2 passes through the point (2, 0)
Also, find the y-intercept by making x = 0 and finding the corresponding y-value
y = x - 2
y = 0 - 2
y = -2
The line passes through the point (0, -2)
Therefore, the graph that represents y = x - 2 is a coordinate plane with a line passing through (0, -2) and (2, 0).

Answer:
"What is your favorite vegetable?" for the first one and Choices A and B are correct for the second one.
Step-by-step explanation:
For the first image/question:
The first survey question is correct and gives you the most data.
"What is your favorite vegetable?"
That question gives a variety of choices and also gives you data similar
to each other.
Ex. 12 people like potatoes, 15 people like corn. 5 people like spinach, etc.
This amount of data is easier to present/graph and also very common/open-ended as opposed to questions like "In which zipcode do you live in?"
Second Question:
The data set can represent the weight of a dozen eggs and could possibly represent the length of leaves from a tree if measured in Centimeters.
A and B are the right choices.
The other few options aren't appropriate due to the data.
A circle has a diameter of 21 meters. What is the circumference of the circle? Use 22/7 for π. (PI)
Answers
Your answer should be:
66
Why...?
Simple.
First, you multiply 21 by 22/7. But to make this easier you have to fix in 'improper fraction.' and make it into an improper fraction. Which will become 3 1/7. Now you multiply 21 and 3 1/7. Which will equal 66. So, 66 is your answer.

divide each side by common to bring x alone
bring 6% to other side now: ? = 600.00 Divided by 6%

Find the percent of change from 45 ft. to 92 ft.
Round to the nearest percent.
PLEASE EXPLAIN HOW YOU GOT THE ANSWER
IF YOU CAN'T EXPLAIN DO NOT ANSWER!!!! PLS AND THANK YOU
Answers
Answer: 104.44%
Step-by-step explanation:
Find the difference between 45 and 92 as a number.
Divide the result from Step 1 by the starting number 45.
Multiply the result from Step 2 by 100 to get it in terms of percent.
The three steps above can be made into a formula. Thus, to find the percent change from 45 to 92, we use this formula:
((Y-X)/X)*100 = Percent Change
X is the starting number 45, and Y is the ending number 92 that it changed to. When we enter these numbers into the formula, we get:
((92-45)/45)*100 = 104.44%
Answer:
So the percentage of change = 204 %
Step-by-step explanation:
Starting value = 45 ft
ending value = 92 ft
Percentage =
So the percentage of change = 204 %

Here are the pairs matched with their products:
- (-5)(4.2) matches with -21
- (-7)(-3) matches with 21
- (2.5)(-9) matches with -22.5
Pairs (4) and (5) do not have corresponding products in the given options.
(-5)(4.2) = -21
(-7)(-3) = 21
(4)(5) = 20
(2.5)(-9) = -22.5
So, the pairs of numbers and their products are as follows:
(-5)(4.2) = -21 matches with -21.
(-7)(-3) = 21 matches with 21.
(4)(5) = 20 matches with 20.
(2.5)(-9) = -22.5 matches with -22.5.
