Answer:
L = 24,873.6 miles
Step-by-step explanation:
Length of the Circumference
Given a circle of radius r, the length of the circumference, or line surrounding the shape is:
[tex]L =2\pi\cdot r[/tex]
The Earth has a diameter of 7,917.5 miles. The radius is half the diameter:
r=7,917.5/2=3,958.75 miles
Assuming a plane flies around the equator at ground level, the distance it would travel is:
[tex]L =2\pi\cdot 3,958.75\ miles[/tex]
L = 24,873.6 miles

The graph shown below represents a ladder leaning against wall the bottom of the latter is 4 feet from the wall in the top of the ladder reach is 20 feet above the ground what is the slope of graph (I’m so sorry I don’t have a picture)
Answer:
C.) -5
Step-by-step explanation:
The slope formula is rise/run, in other words, rise divided by run or the y variable divided by the corresponding x variable.
In this question, we are told that the y-value is "20 feet above" meaning this is the rise and the run is "4 feet from"
To find the slope all we have to do is divide 20 by 4 giving us 5. Since the ladder is going down we know that we have to place a negative sign before the slope giving us our final answer of -5
Which of the following equations is equivalent to 3 • 12 = 36?
36 + 3 = 12
36 ÷ 3 = 12
36 • 3 = 12
36 – 3 = 12
Answer:
B
Step-by-step explanation:
36 ÷ 3 = 12 is basically the division version of the original equation. None of the other equations equal the same answer so B is the correct option.
36 ÷ 3 = 12 is equivalent to 3 • 12 = 36
what are major turning points in algebraic knowledge through out history
Answer:
There are a lot of turning point in the history of algebra one of those is the discovery of the plain and the quadrants by Rene Descartes. This discovery paved way to a lot of knowledge which was later on use in solving other complicated mathematical problems.

1. What is the domain of the function graphed on the grid?
Answer:
[-2,4]
Step-by-step explanation:
The domain is just asking for all the possible x values
we can see that the lowest x value is -2 and the highest is 4 which means our answer is
[-2,4]
Answer:
Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the
x
-axis. The range is the set of possible output values, which are shown on the
y
-axis. Keep in mind that if the graph continues beyond the portion of the graph we can see, the domain and range may be greater than the visible values.
We can observe that the graph extends horizontally from −5 to the right without bound, so the domain is [−5,∞). The vertical extent of the graph is all range values 5 and below, so the range is (−∞,5]. Note that the domain and range are always written from smaller to larger values, or from left to right for domain, and from the bottom of the graph to the top of the graph for range.

Write a quadratic function in vertex form whose graph has the vertex ( -5. - 1) and passes through the point (-2.2).
Answer:
[tex](\frac{1}{3})(x+5)^2-1[/tex]
Step-by-step explanation:
So first let's write a graph in vertex form with a vertex of (-5, -1)
We get
a(x+5)²-1
We now need to determine a
we know that when x= -2 y=2 which means we have
a(-2+5)²-1=2
Solve for a
a(3)²=3
9a=3
a=3/9
a=1/3
Now that we know what a is equal to we can write our equation
[tex](\frac{1}{3})(x+5)^2-1[/tex]

Answer:
Step-by-step explanation:
Divide both sides by 1/3, which is equivalent to mulitplying by 3
x - 10 = -12
Add 10 to both sides
x = -2

Answer:
65
Step-by-step explanation:
the square means 90 add that to 25 and subtract from 180
Answer:
x = 65
Step-by-step explanation:
The measure of the entire angle is 180°. The angle on the furthest left (with a square in it) is a right angle, meaning that it is 90°.
All three of the angles (90°, x°, 25°) all add up to the measure of the line, which is 180°. So, we can write this equation.
90 + x + 25 = 180
Subtract 90 and 25 from both sides.
90 + x + 25 - 90 - 25 = 180 - 90 - 25
x = 65
2. Noah said, "I think this line is a good fit because it passes through the leftmost point and the rightmost point." Do
you agree?

Verizon charges $200 to start up a cell phone plan. then there is a $50 charge each month. what is the total cost for .x months
Answer:
200 + 50x
Step-by-step explanation:
depending on what x is, you multiply x by 50 and add 200, since 200 is the start up fee and the constant. the 50 dollars per month is a variable, since the more months you own the plan, the more money it would cost.

A circular running track is 1/2 mile long. Elena runs on this track completing each lap in 6 minutes how long will it take Elena to run 3 miles?
Answer:
36 mins
Step-by-step explanation:
0.5 miles/6 mins = 3 miles/x mins
In order to convert the ratio from 0.5 miles to 3 miles, 0.5 was multiplied by 6. Therefore, to keep the ratio the same, 6 minutes must also be multiplied by 6 to find x. This means the answer is:
3 miles/36 mins
Which table represents a linear function?
Answer:
My laptop doesn't make me see images, but its the one where you subtract the x coordinates and it has the same answer and when you subtract the y coordinates, it has the same answer
Step-by-step explanation:
Imagine: x = 2, 4, 6, 8, 10 and y = 4, 8, 12, 16, 20
For the x,
4 - 2 = 2
6 - 4 = 2
8 - 6 = 2
10 - 8 = 2
Notice how the answers are all equal to 2
And for the y,
8 - 4 = 4
12 - 8 = 4
16 - 12 = 4
20 - 16 = 4
Notice how the answers are all equal to 4
