Given the relation:
[tex]\mleft\{\mleft(3,0\mright),(-2,6),(-1,4),(-2,0),(1,5)\mright\}[/tex]The range of the relation can be thought of as the set of y-coordinates of a point (x, y). That is, as every second number of the ordered pairs. Additionally, the set should be ordered, and should not contain repeated values. This set is:
[tex]Range=\mleft\lbrace0,4,5,6\mright\rbrace[/tex]Which table shows a relationship with a constant rate of change of 9?
Option C
Explanations:The rate of change is given by the equation:
[tex]\text{Rate of change = }\frac{\triangle y}{\triangle x}[/tex]For the rate of change to be constant, Δy / Δx must be the same for all parts of the table.
In table A, the constant rate of change is (9-9)/(4-2) = 0
In table B, the constant rate of change is (13-11)/(4-2) = 2/2 = 1
In table C, the constant rate of change is (36-18)/(4-2) = 18/2 = 9
In table D, the constant rate of change is (10-9) / (4-2) = 1/2
Only table C has a constant rate of change of 9

RIGHT TRIANGLEA triangle is classified as a right triangle when it presents one of your angles equal to 90º. The greatest side of a right triangle is called the hypotenuse. And, the other two sides are called legs.
The math tools applied for finding angles or sides in a right triangle are the trigonometric ratios or the Pythagorean Theorem.
The Pythagorean Theorem says: (hypotenuse)²= (leg1)²+(leg2)² . And the main trigonometric ratios are: sin (x) , cos (x) and tan (x) , where:
sin (x) = [tex]\frac{opposite\ leg}{hypotenuse}[/tex]
cos(x)=[tex]\frac{adjacent\ leg}{hypotenuse}[/tex]
tan (x) = [tex]\frac{\frac{opposite\ leg}{hypotenuse} }{\frac{adjacent\ leg}{hypotenuse} } = \frac{opposite\ leg}{adjacent\ leg}[/tex]
The question gives the following identity: [tex]\frac{cos (x)+sin(x)}{sin(x)}[/tex]
First, you should rewrite the identity using the cosecant identity - csc(x)= 1/sin(x) . Then,
(cos(x)+sin(x)) * csc(x)
After that, you should expand the previous expression.
cos(x)*csc(x) + sin(x) * csc(x)
cos(x)*1/sin(x) + sin(x) * 1/sin(x)
cos(x)/sin(x) + sin(x)/sin(x)
cot(x) + 1

The probability that the customer came for lunch and did not order dessert is 7/113
The probability that the customer came for lunch or did not order dessert is 93/113
What is probability?It is the chance of an event to occur from a number of possible outcomes.
It is given by:
Probability = Number of required events / Total number of outcomes
We have,
Total number of customers = 113
Desert Non desert
Lunch 7 1 3

The probability that the customer came for lunch and did not order dessert:
= 7 / 113
The probability that the customer came for lunch or did not order dessert:
= (7+13)/113 + (13 + 63)/113
= 20/113 + 73/113

A note with a face value of $8200 was discounted If the discount was $200, the length of the loan in days will be 178 Days.
A loan is when money is lent to another person with the understanding that it would be repaid, along with interest. Before agreeing to provide a borrower with a loan, lenders will take into account the borrower's income, credit score, and degree of debt.
Let us consider the number of days to be 'D'
8200 * 5% * (D / 365) = $200
D = (200 * 365) / (8200 * 0.05)
D = 7300 / 41
D = 178 Days.

What is the distance between the points (−3, −5) and (−3, −7)?
The distance between the points (−3, −5) and (−3, −7) is 2 units.
How to use distance formula?The distance formula gives the shortest distance between two points in a two-dimensional plane.
The distance formula is a useful tool for calculating the distance between two points.
Therefore,
d = √(x₂ - x₁)²+(y₂ - y₁)²
Let's find the distance between the points (−3, −5) and (−3, −7).
Hence,
x₁ = -3
x₂ = -3
y₁ = -5
y₂ = -7
d = √(-3 + 3)² + (-7 + 5)²
d = √(-2)²
d = √4
d = 2
Therefore, the distance between the point is 2 units.

Is his answer reasonable: No, Emtiaz's answer is not reasonable because he assumed that the rate of descent was proportional.
What is the average rate of change?The average rate of change is a type of function that describes the average rate at which a quantity decreases or increases with respect to another quantity.
Next, we would determine the rate at which the skydiver falls per seconds:
Rate = time/distance
Rate = 100/0.8
Rate = 125
Also, an equation which models the height (h) of the skydiver at a 0.8 seconds is given by:
h = 125t
At 3.1 seconds, we have:
Rate = time/distance
Rate = 500/3.1
Rate = 161.3
At 1.5 seconds, we have:
Rate = time/distance
Rate = 187.5/1.5
Rate = 125
Therefore, the average rate of change at each time interval is not equal and as such Emtiaz's answer is not reasonable because the rate increases as the time increases.

What does the statement H(R)=4H(R)=4H, left parenthesis, R, right parenthesis, equals, 4 mean?
The height of the ball at a horizontal distance of R meters from Kaori is H(R)=4H.
Kaori taking a free throw is a guarantee. H(d) simulates the basketball's height (in meters) at d meters of horizontal separation from Kaori.
It is said that H(R) = 4H.
In this case, H(R) displays the height of a basketball instead of H(d). Therefore, it is evident that a basketball's height is 4H since H(R)=4H at d = R.
The horizontal distance from Kaori is R because d is the horizontal distance from Kaori.
Thus the height of the ball is 4H meters at a horizontal distance of R meters from Kaori, according to the expression H(R)=4H.

What is a rule for the translatiARST? Select all that apply.R
Explanation:
Let's identify the coordinates of the initial and final triangle.
R = (-4, 5)
S = (-2, 5)
T = (-4, 1)
In the same way,
R' = (3, 2)
S' = (5, 2)
T' = (3, -2)
So, we can say that the translation was 7 units to the right and 3 units down, so the rule will be:
(x, y) ---> (x + 7, y - 3)
If we apply this rule to the points R, S, and T, we get:
R(-4, 5) ---> (-4 + 7, 5 - 3) = R'(3, 2)
R(-4, 5) ---> (-4 + 7, 5 - 3) = R'(3, 2)
R(-4, 5) ---> (-4 + 7, 5 - 3) = R'(3, 2)

A jacket costs $50.50 more than a pair of sneakers. If the total cost of both items is $200.00, find the cost of each
The total cost of a Jacket is $124.75 and the cost of pair of sneaker is $74.75.
Let us say that the cost of the pair of sneakers is X dollars.
According to the given situation,
Cost of One jacket is 50 dollars more than the cost of a pair of sneakers.
Cost of one jacket = $(50 + X).
Total cost of one jacket and one pair of sneakers is $200.
Total cost of jacket and sneakers = $200
We get,
X + (X+50.5) = 200
2X + 50.5 = 200
The above equation that we have got is linear equation in one variable because it has degree 1 and one 1 variable.
Further solving the equation,
2X + 50.5 = 200
2X = 149.5
X = 74.75
So, the cost of one pair of sneakers is $74.75
Cost of One jacket is $(X + 50.5).
Cost of one jacket = $124.75.
So, one jacket costs $124.75 and sneakers cost $74.75.
