Answer: Choice D

Domain: {-3, -1, 2, 4, 6}  

Range: {-2, 1, 2, 4, 6}

===========================================

Explanation:

The domain is the set of possible x values of a relation or function. To form the domain, we just list out the x coordinates of each point

Point A is located at (-3, 4) so the x coordinate x = -3 is part of the domain

Point B is at (-1,1) meaning x = -1 is also part of the domain

And so on. Doing this for all five points leads to the list of x coordinates {-3,-1,2,4,6} which is the domain.

--------------------

The range is a similar story, but we look at the y coordinates now. Point A has y coordinate 4, so y = 4 is part of the range.

Point B has y coordinate y = 1, so that is also part of the range.

The range is {-2, 1, 2, 4, 6} representing all of the possible y values of this relation.

With any set, the order does not matter. Though convention is to list the items from smallest to largest.

Antonela is planning on painting her room. A gallon of paint covers 110 square feet.
If Antonela's room is 10 feet by 8 feet and has an 8 foot ceiling, how many gallons

She would have to buy 6 gallons of paint because 10 times 8 times 8 = 640 then divide that by 110 which equals something like 5.8 rounded up to 6

Aliaa uses deductive reasoning to identify the number angles that fit inside a circle based on her knowledge that obtuse angles have measures greater than  and that there are  at the center of the circle. Aliaa wants to partition the circle in 3 congruent angles, what is the angle measurement that best fits Aliaa's circle partition?

Answers

Answer:

The best angle measurement that best fits Aliaa's circle partition is three angles of 120° each.

Step-by-step explanation:

The sum of angles at the center of the circle = The sum of angles at a point = 360°

Therefore, to partition the circle into three congruent angles, the measurement of each of the partition should be 360°/3 = 120°

The steps to partition a circle into three are;

1) Draw the diameter of the circle, to intersect the circumference of the circle at points A and B

2) Mark a point, C, at a distance of half the radius from the center of the circle,  O, to the point, B, on the circumference, using a straight edge

3) Draw a perpendicular line to the diameter of the circle, through the point, C, to intersect the circle circumference at points D and E)

4) Draw radial lines from the circle center, O, to the points D and E

5) The segments OA, OB, and OE, are segment lines partitioning the segment into three congruent angles.

Ariana has atoy car collection. She keeps 14 of the toy cars on her wall, which is 35% of her entire collection. What is the total number of toy cars in Ariana's collection?

Answers

Answer:

40 cars

Step-by-step explanation:

The total percentage of Ariana's car collection should be = 100%

35% of the collection = 14

1 percent = 14/35

1 percent is therefore 0.4

To get the total number of cars in Ariana's collection, we multiply 100 by 0.4

= 100 x 0.4 = 40

Therefore the total number of cars in her collection is equal to 40 and this is the answer to the question.

Another way to solve this is by cross multiplication

35% = 14

100% = ?

When we cross multiply we have:

(100x14)/35

= 1400/35

= 40

Answer:

-17

Step-by-step explanation:

ok well I can't really see Sam and John's answer but -3-14 is equal to -17

if you see that there's a negative in front of the first number and its also subtracting you have to make that subtract sign an addition sign then change the second number to a negative like this:

What is the distance between two points of a line?

The distance between two points of a line is given as:

Distance = [tex]\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]

We have,

The polygon is formed by joining the four-point:

(0, b), (-a, 0), (a, 0), and (0, -b)

The distance between two points (x1, y1) and (x2, y2) is given by the formula:

[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]

Now,

Using this formula, we can find the lengths of the sides of the polygon:

The distance between (0, b) and (-a, 0) is d1.

= √[(0 - (-a))² + (b - 0)²]

= √(a² + b²)

The distance between (-a, 0) and (0, -b) is d2.

= √[(0 - (-a))² + (-b - 0)²]

= √(a² + b²)

The distance between (0, -b) and (a, 0) is d3.

= √[(0 - a)^2 + (0 + b)^2]

= √(a² + b²)

The distance between (a, 0) and (0, b) is d4.

= √[(0 - a)²+ (b - 0)^2]

= √(a² + b²)

The perimeter of the polygon is:

P = d1 + d2 + d3 + d4

= 4√(a² + b²)

Thus,

The perimeter of the polygon is 4√(a² + b²).

Step-by-step explanation:

[tex]c=\frac{5\left(f-32\right)}{9}[/tex]

Switch sides:

[tex]\frac{5\left(f-32\right)}{9}=c[/tex]

Multiply both sides by 9:

[tex]5\left(f-32\right)=9c[/tex]

Divide both sides by 5:

[tex]f-32=\frac{9c}{5}[/tex]

Add 32 to both sides:
