Answer:
Step-by-step explanation:
The rule that makes a relation NOT a function is if there are shared x values. This function has 2 points with the same x value:
(7, 4) and (7, 6). The sharing of these x-values (or the repeating of them) within the same relation makes this NOT a function. The last choice is the one you want. Just remember that a relation is only a function if there are no shared x-values. The y-values don't matter to this at all. A relation would be a function if it were made up of the following coordinates:
(1, 2), (2, 2), (3, 2), (4, 2), (5, 2), etc. Again, as long as the x-values don't repeat, the relation is a function.

Aliza needs to run at a rate faster than 8.2 feet per second in order to exceed her fastest time in a race. After running for 15 minutes, her coach determines that she is running at an average rate of 5.8 miles per hour. He converts the average rate to feet per second as shown below:
He concludes that she is not running fast enough to exceed her fastest time.
What errors did the coach make? Check all that apply.
He used an incorrect time ratio converting hours to minutes.
His units do not cancel.
He used an incorrect distance ratio converting miles to feet.
He incorrectly concluded that she is not running fast enough.
He cannot determine her average rate in miles per hour after only 15 minutes.
Answer:
A) He used an incorrect time ratio converting hours to minutes.

Can all polynomials be factored the same way? Why or why not?
Answer:
No, they cannot. Some polynomials are different than others and can be factored in different ways. Some can't even be factored at all.
Perfect Square Trinomials have a pattern with factoring and can be written as one binomial squared.
Difference of Squares has a pattern of (x - y)(x + y).
Difference/Sum of Cubes have formulas for their patterns.
Prime Polynomials simply cannot be factored.

Step 5

Where is the mistake
Answer:
See below
Step-by-step explanation:
Step 2 and Step 3
Mistake #1: From step 1 to step 2 the 32 randomly changed to 9
Mistake #2: According to PEMDAS multiplication and division comes before addition and subtraction.
During step 3, 8 was added to -6 before 8 was multiplied by 7 which is incorrect as the multiplication should come first.
The real answer should be....
-6 +8(11 - 4)+ 32
Evaluate using PEMDAS
Parenthesis
Exponents
Multiplication and division (left to right)
Addition and Subtraction (left to right)
-6 +8(11 - 4)+ 32
First do the operations inside of the parenthesis. ( Subtract 4 from 11 )
-6 + 8(7) + 32
There are no exponents so we go to the next step.
Next is multiplication.
Multiply 8 and 7
- 6 + 56 + 32
Finally we do the addition and subtraction going left to right.
First add 56 to -6
50 + 32
Then add 50 and 32
= 82
Answer: Step 2 and Step 3.
From step 1 to step 2 the "32" unexpectedly changes into a "9" for no reason.
Step 3 also has a mistake due to misusing PEMDAS, as 6 is removed from the 8(7) to get 2. The 6 should be removed from the 32 instead.
Correct step-by-step explanation:
[tex]-6 + 8(11-4) + 32\\=-6+8(7)+32\\=-6+8(7)+32\\=8(7)+26=56+26\\=82[/tex]
The surface area of a sphere is a function of the radius of the sphere: A = 41182.
Evaluate the function for a basketball with a radius of 11.5 cm.
The value of the function of the surface area of a sphere when the radius is 11.5 cm is approximately 1661.9 cm²
The process of arriving at the above value is as follows;
The known parameter
The function of the radius representing the surface area of a sphere is, f(r) = A = 4·π·r²
The radius of the basketball, r = 11.5 cm
Required;
To evaluate the function, f(r), for the basketball
Method;
The process of evaluating a function, is to find the value of the function at a given value of the input or independent variable of the function
The input variable is the variable that determines the output value of the function, it is the variable which is the function is about
In the question, the function given is dependent on the radius, r
To evaluate the value of the function, we substitute the value of r in the equation of the functionTherefore;
When r = 11.5 cm (the radius of the basketball), from the function, the surface area of the basketball, A = f(11.5) = 4 × π × (11.5 cm)² ≈ 1661.9 cm²
Therefore;
The evaluation of the function which is the value of the function, f(r) = A,
when the radius, r, is 11.5 cm, which is the surface area of the spherical
basketball, is A ≈ 1661.9 cm²

Step-by-step explanation:
The Law of Sines is a property that relates the sides and angles of any triangle. This property states the following:
[tex]\frac{sin(A)}{a}=\frac{sin(B)}{b}=\frac{sin(C)}{c}[/tex]
Where (A), (B), and (C) are the angles of the triangles. The sides (a), (b), and (c) are the sides opposite their respective angles, (side (a) is the opposite angle (<A); side (b) is the opposite angle (<B); and side (c) is the opposite angle (<C)). Substitute the given information into the formula and solve for the unknown:
[tex]\frac{sin(A)}{a}=\frac{sin(B)}{b}=\frac{sin(C)}{c}[/tex]
[tex]\frac{sin(A)}{a}=\frac{sin(72)}{b}=\frac{sin(53)}{18}[/tex]
Remove the parts of the equation that are not relevant to the problem,
[tex]\frac{sin(A)}{a}=\frac{sin(72)}{b}=\frac{sin(53)}{18}[/tex]
[tex]\frac{sin(72)}{b}=\frac{sin(53)}{18}[/tex]
Take the cross product of the proportion,
[tex]\frac{sin(72)}{b}=\frac{sin(53)}{18}[/tex]
[tex]18(sin(72))=b(sin(53))[/tex]
Inverse operations,

1) What happens when production is inside the production possibilities curve?
The production is not maximized, so some resources are unused.
The production is not maximized, so some resources are unused.
The production has become less efficient, and eventually the curve will shift inward.
The production has become less efficient, and eventually the curve will shift inward.
The production has been made more efficient, and eventually the curve will shift inward.
The production has been made more efficient, and eventually the curve will shift inward.
It is not possible for the production to move inside the curve.
When production is inside the production possibilities curve, it means that the production is not maximized because some resources are unused.
A production possibility curve shows how an economy can be able to produce two goods while making use of the resources that it has. It follows the principle of trade off because as the production of a particular good is increased, the other good has to be reduced.
Production on the production possibility curve shows that the economy is making efficient use of the resources that it has.
When the production is inside the production possibility curve, it means such economy isn't making efficient use of the resources that it has.
Therefore, the correct option is A.

Find the total payment,
given the cost, sales tax
rate, and tip rate.
Cost: $35.75
Sales Tax Rate: 5%
Tip: 15%
Answer:
The total payment is thus $35.75 plus $7.11, or $42.86
Step-by-step explanation:
Note that the sales tax doesn't affect the tip. The sales tax is 5% of the cost and the tip is 15% of the before tax cost. We calculate the tax and the tip separately, then add them together and finally add this sum to the cost.
Sales tax: 5% of $35.75: $1.75
Tip: 15% of $35.75: $5.36
Adding these two quantities results in $7.11.
The total payment is thus $35.75 plus $7.11, or $42.86

What is an equation?An equation is written in the form of variables and constants separated by the operation of multiplication and division,
An equation states that terms in different forms on both sides of the equality sign are equal.
Multiplication and division do not separate the terms of an equation.
Given, The price per pound of the cherries is $4 per pound and she has a coupon for $3.50 off the final amount.
Therefore, The cost of 3 pounds of cherries before the discount would be,
= $(3×4).
= $12.
And after the discount, it would be $(12 - 3.50).
= $8.50.
An expression for the cost to buy p pounds of cherries would be,
= $(4p - 3.50)
