What is the range of the function f (x)= 4x -6 when the domain is { -4,-2,0,2,6}?
Answer:
{-22, -14, -6, 2, 18}
Step-by-step explanation:
f(-4)=4(-4)-6=-22
f(-2)=4(-2)-6=-14
f(0)=4(0)-6=-6
f(2)=4(2)-6=2
f(6)=4(6)-6=18
What's the circumference of a circle with a diameter of 9 inches?
Answer:
9pi
Step-by-step explanation:
circumference= 2 (pi) (r)
radius = diameter \ 2
r = 9 \ 2 = 4.5in.
c = 2 (pi) (4.5)
c = 9pi or 28.3in.

A tuxedo shop rents its tuxedos for $30 per day. They charge a nonrefundable fee of $ 60 for each tuxedo.
Use the dropdown boxes to create an equation that could be used to determine the total cost, y of renting a tuxedo for x days.
Given parameters:
Charge per day of Tuxedo = $30 per day
Non-refundable charge = $60 for each tuxedo
Unknown:
Equation to determine total cost = ?
Solution:
Represent;
Total cost = y
Number of days = x
Now;
Total cost = Non refundable charge + charge per day
y = $60 + $30x
The equation is;
y = 60 + 30x for a tuxedo

A new concert venue just opened in downtown Augusta and they are in the process of deciding how many tickets they can sell for each show. The venue has three levels, two general admission that only have standing room, and one level with 240 seats. The first level of standing room is a square with one side measuring 80'. The second level, also standing room, is a rectangle measuring 120' by 30' ft. The third level has 240 seats. The venue thinks each person will occupy 2.5 square feet. How many tickets should they sell?
Answer:
4,240 tickets
Step-by-step explanation:
The first level of standing room is a square with one side measuring 80'.
Area of the first level = length^2
= 80^2
= 6,400 square ft
The second level, also standing room, is a rectangle measuring 120' by 30' ft.
Area of the second level = length × width
= 120 × 30
= 3,600 square ft
Total area of the standing rooms = (6,400 + 3,600) square ft
= 10,000 square ft
Each person in the standing room will occupy 2.5 square ft
Number of Persons that will occupy the standing room = Total area of the standing rooms / 2.5 square ft
= 10,000 square ft / 2.5 square ft
= 4,000
Therefore the number of Tickets that should be sold
= Number of seats + Number for standing Room
= 240 + 4000
= 4,240 tickets

what is the answer when you simplify?.
Answer:
C
Step-by-step explanation:
Because when you multiply 4³ × 4^4 = 16384
And 4^9 = 262144
(divide) 16384/262144 = .0625
.0625 = [tex]\frac{1}{16}[/tex]
[tex]\frac{1}{4^2}[/tex] = [tex]\frac{1}{16}[/tex]
because 4 * 4 = 16

The lengths of pregnancy terms for a particular species of mammal are nearly normally distributed about a mean pregnancy length with a standard deviation of 7 days. About what percentage of births would be expected to occur within 7 days of the mean pregnancy length
Answer:
68.268%.
Step-by-step explanation:
Let \mu be the mean pregnancy length.
The given standard deviation, [tex]\sigma=7[/tex] days
The z-score:
z=\frac{x-\mu}{\sigma}
where x is any pregnancy length.
The range of x within 7 days of the mean pregnancy length is
[tex]\mu-7<x<\mu+7.[/tex]
z-score for this range is:
[tex]\frac{\mu-7-\mu}{\sigma}<z<\frac{\mu+7-\mu}{\sigma}[/tex]
[tex]\Rightarrow -1<z<1[/tex]
So, the area on the normally distributed curve for the above range of z-score will give the expected percentage of birds to occur within 7 days of the mean pregnancy length.
Now, from the z-score table:
The area from [tex]z = -\infty[/tex] to z=1 is 0.84134
and the area from [tex]z = -\infty[/tex] to z=-1 is 0.15866.
So, the area for -1<z<1
=0.84134 - 0.15866
=0.68268
Hence, the percentage of births would be expected to occur within 7 days of the mean pregnancy length=68.268%.

The perimeter of a rectangle is found by multiplying the sum of the length, shown as LaTeX: ll, and the width, shown as LaTeX: ww, by LaTeX: 22. The length of a certain rectangle is LaTeX: 2020 . Which inequality shows that the perimeter of this rectangle is less than LaTeX: 5757 units?
Answer:
40 + 2W < 57
Step-by-step explanation:
Given that:
Perimeter of a rectangle (P) :
P = 2(length(L) + width(W))
If the length of a certain rectangle L = 20 ; which inequality shows perimeter of rectangle is less than 57 units
P = 2(length(L) + width(W))
40 + 2W < 57
A steel beam can be cut to different lengths for a project.
Assuming the weight of a steel beam is proportional to its length, what information would you need to know to write an equation that represents this relationship?
Answer:None
Step-by-step explanation:
You can write a statement of proportionality without any additional information:
weight = k × length for some constant k
If you need to know the specific weight of a specific length, then you need to know the constant of proportionality (the value of k).
Write the phrase as an expression.

To find m, we can use the formula y2 - y1 / x2 - x1
x1 = 2
y1 = 50
x2 = 4
y2 = 90
Let's plug these numbers into our formula.
m = 90 - 50 / 4 - 2 = 40/2 = 20
So far our equation looks like: y = 20x + b
Now, let's plug one of the points into our equation.
50 = 20(2) + b
Simplify
50 = 40 + b
Subtract 40 from both sides.
10 = b
The final equation is: y = 20x + 10
(x²+7x+10) =

hope this helps (:
The length from the vertex to the centroid is twice the length from the
centroid to the midpoint of the opposite side.
x is 37Segment [tex]\overline {DG}[/tex] is 22Segment [tex]\overline {GA}[/tex] is 44Segment [tex]\overline {AD}[/tex] is 66Reasons:
The known parameters are;
The centroid of ΔABC = Point G
Segments [tex]\overline {AD}[/tex], [tex]\overline {BE}[/tex], and [tex]\overline {CF}[/tex] are the medians of ΔABC
Length of line segments [tex]\overline {DG}[/tex] = x - 15
Length of line segments [tex]\overline {GA}[/tex] = x + 7
Required:
The value of x, and lengths of the segments of median [tex]\overline {AD}[/tex]
The median is divided at the centroid of the triangle to ratio 2:1
[tex]Length \ of \ line \ segment \ \overline{GA} = \dfrac{2}{3} \times \overline{AD}[/tex]
Therefore;
[tex]\overline{AD} = \mathbf{\dfrac{3}{2} \times \overline{GA}}[/tex]
[tex]Length \ of \ line \ segment \ \overline{DG} = \mathbf{\dfrac{1}{3} \times \overline{AD}}[/tex]
Therefore;
[tex]\overline{AD} = 3\times \overline{DG}[/tex]
Which gives;
[tex]\dfrac{3}{2} \times \overline{GA} = 3\times \overline{DG}[/tex]
Therefore;
[tex]\dfrac{3}{2} \times (x + 7) = 3\times (x - 15)[/tex]
3·x + 21 = 6·x - 90
21 + 90 = 6·x - 3·x
111 = 3·x
3·x = 111
[tex]x = \dfrac{111}{3} = 37[/tex]
x = 37
[tex]\overline {DG}[/tex] = x - 15
The length of line segment [tex]\overline {DG}[/tex] = 37 - 15 = 22
[tex]\overline {GA}[/tex] = x + 7
Length of line segment [tex]\overline {GA}[/tex] = 37 + 7 = 44
[tex]\overline {AD}[/tex] = [tex]\overline {DG}[/tex] + [tex]\overline {GA}[/tex]
Therefore;
Length of line segment [tex]\overline {AD}[/tex] = 22 + 44 = 66

The cost of the hiking trip is 2/3 of the cost of last years trip this year trip cost $32 write and solve an equation to find the cost of last years trip
Answer:
(32/2)*3=48
Step-by-step explanation:
In order to find the answer, we must find one third of last year's trip. To do this, we can simply divide the cost of this years trip by two, 32/2=16.
Now if we multiply this this number by 3, 16*3=48, we can see that the total cost of last year's trip was $48.
If we'd like to turn this into one equation, it looks like this: (32/2)*3=48
