If the relation is a function, list the domain and range. If the relation is not a function, choose "not a function".

Answer:

D or last answer choice.

Step-by-step explanation:

Separate the figure into 2 parts. A rectangle and a triangle.

The rectangle has a width of 3 and a length of 7 therefore 1 or the equations should be 7*3

The triangle has a width of 6 and 7 and to find the area of a triangle you need to see the triangle as a rectangle or square and then multiply 1/2 to the product.

Answer:

Its the last choice, (7*3) + 1/2 (7*6)

Answer:

Step-by-step explanation:

The discriminant of this equation, i.e, D=\(b^{2}-4ac\) is less than 0:

D= 0-(4*2*18)   --> which is clearly negative

When D is less than 0, the equation has no real number solutions.

Therefore, \(2x^{2}+18=0\) has no real roots

By solving the equation y-555 = -22(0-12), we got that statements

(a) True

(b)False

(c) True

An linear equation in two variable is an statement that compares two linear expression in two variables using equal to sign.

Let x and y be two variables then the linear equation in these two variable in standard form is ax+ by+ c = 0 , where a, b, c are constants.

Given, the equation y-555 = -22(x-12) represents y as a function of x , where y is the number of Lego pieces Jefferson has left to build and x is the number of minutes he has been building. When x = 0 means that Jefferson has not started building the Lego therefore  y = all Lego pieces

y-555 = -22(0-12)

⇒y -555 = 22*12

⇒ y = 555 +264 = 819

It means that total Lego pieces were 819 not 555

Therefore, (b) statement is false.

Simplify:     y-555 = -22(x-12)

⇒ y-555 = -22x + (22*12)

⇒ y- 555 = -22x +264

⇒ y = - 22x +264 +555

⇒ y = -22x +819

Therefore , this situation can be represented by  y = -22x +819

Thus , (c) statement is true

Also, from this relation ship we can see that initially there were 819 Lego pieces and when x =1 , y = 819 -22, when x=2 then y =819 - 2(22)

and so on .This means that every minute Jefferson removes 22 Lego pieces from box to assemble X- wing.

Thus (a) is an true statement.

Therefore, by solving the equation y-555 = -22(0-12), we got that statement (a) and (c) are true and (b) is false.

Answer:

Area: 40 cm Perimeter: 30 cm

Step-by-step explanation:

When finding the area of a parallelogram, you use the inside length (in this case, 5cm) and the base (8cm). With perimeter, you use the base and the length (6cm).

8*5=40

8+8+6+6=30

The function for the points are  y = -15x - 5

From the information given, we have that;

The points are;

(1/3,0) (-2 3/4,0) and (0,-5)

Using the point-slope form of a linear equation, we have;

y - y₁ = m(x - x₁)

Such that;

Using (1/3, 0) and (0, -5), we have that the slope is;

m = (0 - (-5))/0 -1/3)

expand the bracket

= 5 / (-1/3)

= -15

Now, take any of the given points and substitute the values

Using (1/3, 0), we get;

y - 0 = -15(x - 1/3).

y = -15x - 5.

The function for the points solved by  (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)

We have given the points:

(1/3,0) (-2 3/4,0) and (0,-5)

Using the formula of linear equation

\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)                                                          

Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)

that is 1/3 = \(a\), 0 = \(a_{1}\) and

0 = \(b\), -5 = \(b_{1}\)

\(x\) refers to the slope of line (take any variable)

Now for finding the value of \(x\),

\(x=a-a_{1}/b-b_{1}\)

inserting the values,

\(x=[0-[-5]]/[0-1/3]\\x= -15\)

Substitute the value of \(x\) in the equation

\(a-0=-15[b-1/3]\)

By simplifying the equation, we get

\(a=-15b-5\)

What you have to do is find the area of the whole rectangle, then subtract of the empty parts:

50*48-0.5(50-41)(48)-6.5(pi(5/2)^2)-1.5pi(4^2)-pi(5^2)-pi=1899.293mm^2

Explanation:

The first subtraction is the area of the triangle.  The rest are the combined areas of the circles and semicircles (semicircles are just half the area of a circle)

Answer:

1899.293mm^2

Answer:

Mean = 33.7

Median = 34.5

Mode = 34

Range = 33

After adding 26....

mean decreases by 0.7

median decreases by 0.5

mode is 34

range is 33

Step-by-step explanation:

mean = sum of all the data values/number of data values

= (18 + 19 + 20  + 34 + 34 + 35 + 37 + 42 + 47 + 51)/10
= 337/10
= 33.7

To find median arrange the values in increasing order, find the mid value

If the number of data points is even, find the average of the mid 2 data values

Arranging data values we get:
18, 19, 20, 34, 34, 35, 37, 42, 47, 51

Since there are 10 data values, take the average of the middle two:
(34 + 35)/2 = 34.5

The mode is the value that occurs most often. We see that there are two instances of 34 whereas the other values appear only once

Mode = 34

The range is highest - lowest = 51 - 18 = 33

After we add 26, we get the following data set arranged

18, 19, 20, 26, 34, 34, 35, 37, 42, 47, 51

we can calculate the stats using the same technique as above

We get the following values

mean = )(18 + 19 + 20 + 26 + 34 + 34 + 35 + 37 + 42 + 47 + 51)/11
= 33  

median = 34

mode = 34

range = 51-18 = 33

To find the decrease in mean and median subtract from the first set of values

Step-by-step explanation:

Answer:  6 to 1

Step-by-step explanation:

A ratio refers to a fraction. In this case the question asks how many players to coaches there are.

The word "to" means that is where the fraction bar goes.

Players/Coaches

There are 18 players and 3 coaches.

18/3

18 can be divided by 3, 6 times so the fraction can be simplified to

6/1 meaning there are 6 players for every coach.
