3. There are inputs such as 25, 29, 30 and 32.5 that are mapped to multiple outputs, hence the relation does not represent a function.

To build the relation, we look at the graph, and write all pairs of (Age, Finishing Place), as follows:

(20,2), (22.5, 5), (25,4), (27.5, 4), (29,4), (29,5), (30,1), (30,2), (30,3), (30,4), (30,5), (32.5, 1), (32.5, 3), (35,4), (40,2), (42.5, 3).

Hence, for the given relation:

The domain is {20, 22.5, 25, 27.5, 29, 30, 32.5, 35, 40, 42.5} and the range is {1, 2, 3, 4, 5}.

A relation represents a function if each value of the input is mapped to only one value of the output.

For this problem, we have that:

There are inputs such as 25, 29, 30 and 32.5 that are mapped to multiple outputs, hence the relation does not represent a function.

Answer:

just use the calculator

Step-by-step explanation:

Answer:

x = -17

Step-by-step explanation:

You can plug in answer choices, or you can get x by itself.

I got x by itself because it is faster. Simply subtract 15 from both sides.

So, you would get x = -2 - 15. Keep change change to subtract negative numbers => -2 + -15 which equals to -17.

So x = -17.

You can also plug it in: 15 + -17 does equal -2.

We get the distance between the coordinates of the point S and T as 5 √2 units.

We are given the coordinates of two points as:

S = ( - 2, 4 )

T = ( 3, 9 )

We have to find the distance between the points S and T.

We will use the distance formula for this.

Distance = √(x₂ - x₁)² + ( y₂ - y₁)²

Here, we have:

x₁ = -2

x₂ = 3

y₁ = 4

y₂ = 9

Substituting the values in the formula, we get that:

Distance = √(3 + 2)² + ( 9 - 4)² units

Distance = √(5)² + ( 5)² units

Distance = √25 + 25 units

Distance = √50 units

Distance = 5 √2 units

Therefore, we get the distance between the coordinates of the point S and T as 5 √2 units.

The given equation r² - 15 = t + 19 is the equation of a parabola with vertex at (h, k) = (0, -34) and focal length |p| = 1/4.

I assume that the question is to describe or graph the equation r² - 15 = t + 19.

The given equation r² - 15 = t + 19 is the equation of a parabola with vertex at (h, k) = (0, -34) and focal length |p| = 1/4.

4p(y - k) = (x - h)² is the common equation for a parabola that faces up and down and has a vertex at (h, k) and a focal length of |p|.

Let us re-write the given equation in the standard form.

r² - 15 = t + 19

⇒ r² = t + 19 + 15

⇒ r² = t + 34

⇒ (r - 0)² = t + 34 (r can be written as r - 0)

⇒ (r - 0)² = t - (-34) (+34 is written as -(-34))

⇒ (r - 0)² = 4 × 1/4 × (t - (-34))

(4 × 1/4 is equal to 1. The given equation is unaffected by a multiplication by 1.)

⇒ 4 × 1/4 × (t - (-34)) = (r - 0)²  this equation is in the standard form. And here we have |p| = 1/4 and (h, k) = (0, -34).

Answer:

sample mean = 12

Step-by-step explanation:

To find the mean of a sample of items, we can use the following formula:

[tex]\boxed{\mathrm{mean = \frac{sum \ of \ items}{number \ of \ items}}}[/tex].

In this question, we are given the following items: 16, 17, 5, 6, and 16.

• sum of items = 16 + 17 + 5 + 6 + 16

                        = 60

• number of items = 5

∴ mean = [tex]\frac{60}{5}[/tex]

             = 12

Therefore, the sample mean is 12.

Answer:

1.6

Step-by-step explanation:

first we want to figure out the square roots. the square root of 12 would be 3.5. while the square root of 3 is 1.7

after figuring out the square roots, our equation is -3.5 + 3(1.7)

first we want to multiply 3 by 1.7

this would give us 5.1

leaving our equation as -3.5 + 5.1

our final step is to add 5.1 to -3.5

although i find it easier to just subtract 3.5 from 5.1 since 3.5 is a negative.

this would give us 1.6

Mr. Farley used 0.4 pounds of hamburger per patty.

The unitary method is a technique used to find the solution by first finding the value of a single unit and then multiplying the value to get the required answer.

Here, we are given that Mr. Farley used 4 pounds of hamburger to

make 10 hamburger patties.

Given that all of these patties are of the same size, an equal amount of hamburger will be used to make each patty.

We have,

For 10 patties, we need ⇒ 4 pounds of hamburger.

Therefore, for 1 patty we will need ⇒ 4/10 pounds

= 0.4 pounds

The compound inequality is: x<20 and x>10

Given,  a quantity of x is greater than 10 and less than 20.

A compound inequality (also known as a compounded inequality) is created when two or more inequalities are coupled with and. One part of an inequality must be true for a value to be a solution to an or inequality. It must make both parts true in order to be the solution to an inequality. X<3 or X>2, for instance.

Divide a compound inequality into two independent ones before attempting to solve it. Choose either a union of sets ("or") and an intersection of sets as the appropriate response ("and"). Then, resolve the graph and all inequalities.

Simply put, a compound inequality is more than one inequality that we want to address simultaneously. When referring to the resolution of both inequalities, we can either use the term "and" or "or."

The total area of the new tile floor in the restaurant = 240 ft².

A geometric figure is any arrangement of points, lines, or other planes. Depending on the proportions of the figure, geometric figures are frequently categorized as space figures, plane figures, lines, line segments, rays, as well as points.

Geometric forms are any open or closed structures with specific shapes and attribute dreamed up of lines, curves, and points. Geometric shapes include square, rectangles, circles, cones, cylinders, sphere, and so on. All of these forms have characteristics that distinguish them from others.

Length of rectangle  = 15ft

width of rectangle = 12ft

hypotonus = 17ft

First finding the area of the rectangular part:

area = L x B

       = 15 x 12

       = 180 ft²

First finding the area of the triangular part:

Area = 1/2 *(B *h)

        = 1/2 * (8 * 15)

        = 1/2 * 120

        = 60 ft²

The total area of the new tile floor in the restaurant = 180 + 60

Step-by-step explanation:

(6x+7) and (8x-17)° are both vertical angles; so, the value of x is 12.

When two straight lines cross, the angles that are opposite one another are called vertical angles. (These two lines should technically be on the same plane.)

Angles vertically are congruent.

According to the given value;

Let the angles be A and B; such that:

A = 6x+7

B=8x-17

By theorem of vertical angles

A = B

So, we have:

6x+7=8x-17

Collect like terms

8x-6x=7+17

2x=24

x=12

Hence the value of x is 12.

A graph of a function is a special case of a relation.

In mathematics, the graph of a function f is the set of ordered pairs, where f(x)=y.

In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y.

Here, we can see that function increases before x = - 2, then it decreases till x = 0, then it again increases from x = 0 to x = 2 and then it again decreases.
