The domain of the following relation: R: {(-4, 3), (3, 6), (-2, 1), (3, 6)} is (1 point)
A.(1, 3, 6}
B.{-4, 3, -2,3)
C.{-4, -2,3)
D.No domain exists
Answer:
C. {-4, -2, 3)
Step-by-step explanation:
The domain of a relation is the x - values.
Duplicate numbers are only listed once
(-4,3)
(3,6)
(-2,1)
(3,6)
So {-4, -2, 3)

A men's shoe size is related to his foot length and can be modeled by the equations s=1.7f -7.2, where s is shoe size and fis foot length, in inches. What is the shoe size of a man whose foot measures 9 inches?
Answer:
B. 8
Step-by-step explanation:
Given the equation, [tex] s = 1.7f - 7.2 [/tex],
where,
s = shoe size,
f = foot length,
To determine the shoe size of a man that has a foot length (f) of 9 in, substitute f = 9 into the equation.
[tex] s = 1.7f - 7.2 [/tex]
[tex] s = 1.7(9) - 7.2 [/tex] (substitution)
[tex] s = 15.3 - 7.2 [/tex]
[tex] s = 15.3 - 7.2 [/tex]
[tex] s = 8.1 [/tex]
His shoe size is approximately 8 inches

Answer:
61, C
Step-by-step explanation:
So, congruent means all the same. The question is just saying that 3 lines intersect at one point and form 6 angle. The 6 angles are not all the same. Given that, what is the smallest possible largest angle. Obviously, if all angles could be congruent, then, it would be 6 60° angles. However, they aren't. So, to minimize the largest angle, we can just make 1 angle 61° and another 59°. Therefore, the answer should be C which is 61° as you would have the 6 angles being:
59°, 60°, 60°, 60°, 60°, and 61°.

A mountain has a 20 degree slope, and is 1 mile tall. How far do you need to hike to reach the summit?
The distance we have to hike to reach the top of the mountain is
2.92 miles.
What are trigonometric ratios in terms of a right-angle triangle?We know a right-angled triangle has three sides they are -: Hypotenuse,
Opposite and Adjacent.
We can remember SOH CAH TOA which is,
sin = opposite/hypotenuse, cos = adjecen/hypotenuse and
tan = opposite/adjacent.
Given, A mountain has a 20-degree slope and is 1 mile tall and we have to hike the mountain so we want to know the distance.
Here hypotenuse is the distance we have to hike and according to the reference, the angle opposite has a distance of 1 mile.
We know sin = opposite/hypotenuse.
sin20° = 1/hypotenuse.
0.342 = 1/hypotenuse.
hypotenuse = 1/0.342.
hypotenuse = 2.92 miles.

Ketut is organizing a barbecue for his parents. He knows that 13 of his mom’s friends prefer hot dogs and 9 of his dad’s friends prefer hamburgers. He organizes a two-way table to determine what he needs to buy. Which describes the variables he can use in the first row and first column of his table?
meal choice and number of mom’s friends
meal choice and number of guests
parent and number who prefer hot dogs
parent and meal choice
Answer:
it is actually d.
Step-by-step explanation:
if you were to create a two way table, it would make sense, but you would still need more information.
Parent and meal choice describes the variables he can use in the first row and first column of his table.
What is sample space?The sample space S of a random experiment is defined as the set of all possible outcomes of an experiment. In a random experiment, the outcomes, also known as sample points, are mutually exclusive.
Given, Ketut is organizing a barbecue for his parents. He knows that 13 of his mom’s friends prefer hot dogs and 9 of his dad’s friends prefer hamburgers.
Variable in a graph should be an object, event, idea, feeling, time period, or any other type of category you are trying to measure. There are two types variables-independent and dependent.
Ketut is organizing a barbecue for his parents. He knows that 13 of his mom s friends prefer hot dogs and 9 of his dad s friends prefer hamburgers. He organizes a two-way table to determine what he needs to buy.

Last year, Gena’s food cart business was $225 in debt. This year, the debt has tripled. Which expressions show how much Gena’s business is currently in debt? Check all that apply.
225(3)
(3)(–225)
–225 + 3
3 – 225
–225(3)
(3)(–225)
–225 + 3
3 – 225
–225(3)
Answer:
(3)(-225) and -225(3).
Step-by-step explanation:
First, since ¨in debt¨ is describing negative value, all of the expressions that have positive 225 is incorrect. Also, since the term ¨triple¨ is describing multiplcation, any expression that does not have multiplication is also incorrect. This process of elimination leads to two answers, which both are correct.
Answer:
A. 225(3)
B. (3)(–225)

The points (10, w) and (3, 1) fall on a line with a slope of 0. What is the value of w?
Answer:
w = 1
Step-by-step explanation:
If the slope is 0, then this line will be horizontal.
This means that the y value will be the same for all points on the line.
Since we are given the point (3, 1), we know that the y value is 1. This means all other points on the line will have 1 as the y value.
So, w is equal to 1 because it is the y value in that ordered pair.

Write each ratio as a fraction in lowest terms
Answer:
1/3
Step-by-step explanation:
If you want to write the fraction in its lowest terms, all you have to do is simplify!! Simplifying is easy; all you have to do is divide on the top and bottom of the fraction by the same number.
So, to simplify 6/18, figure out what the highest number is that can go into both numbers in the fraction. For this problem, the highest number is 6.
6 divided by 6 is 1.
18 divided by 6 is 3.
The simplified answer comes out as 1/3...you can also check it by multiplying 1 and 3 by 6.
1 multiplied by 6 is 6.
3 multiplied by 6 is 18.
So, 6/18 in lowest terms is 1/3!!

[tex]y=x^{2} -5x+7\\y=2x+1[/tex]
Answer:
x = 6, and x = 1
Step-by-step explanation:
If each expression equals y, the simplest approach would be to equate them;
x^2 - 5x + 7 = 2x + 1 => Isolate all the terms on one side
x^2 - 5x - 2x + 7 - 1 = 0 => Combine like terms
x^2 - 7x + 6 = 0 => solve using quadratic equation
x = ( - (- 7) + √( - 7)^2 - 4 * 1 * 6 )/ 2 * 1
= 7 + √25 / 2 = 7 + 5 / 2
= 6
x = ( - (- 7) - √( - 7)^2 - 4 * 1 * 6 )/ 2 * 1
= 7 - √25 / 2 = 7 - 5 / 2
= 2 / 2 = 1

Step-by-step explanation:
All straight lines have a degree of 180, so the angle measures all have to add up to 180 degrees.
Answer:
4) 120°
5) 20°
6) 55°
Step-by-step explanation:
4) 180°-60°=120°
5) 180°-160°=20°
6) 90°+35 = 125°
180°-125°=55°
