While on vacation, Jorge and Jackie traveled to Bryce Canyon National Park in Utah. They were impressed by the different elevations at the viewpoints along the road. The graph describes the elevations for several viewpoints in terms of the time since they entered the park. The graph represents a function E(t). Part A:Describe why the graph represents a function. Part B:Identify the domain in range of the function.
Answer:
timeline
Step-by-step explanation:
the table shows the same time I don't have your phone you u you y you can get a hold of y have a lot to do it you got a
The domain and range provides a definition for a graph
Part A: The graph represents a function because a vertical line drawn from the horizontal crosses the graph only once
Part B. Domain: 0 ≤ t ≤ 30
Range: 7000 < f(t) ≤ 9,300
Reason:
Part A: The reason why the graph represents a function is that a function is a one to one relationship that maps each element of the set known as the domain to exactly one element of the set which is the range of the function
Therefore, a vertical line drawn on the graph of a function crosses the graph only once, such that one input cannot have two outputs
Which gives that the graph is a function, given that all the vertical lines from the horizontal axis crosses the graph f(t) at exactly one point
Part B
Domain:
The domain of a function are the possible input values of the function
In the graph, the possible values of the time, t are; 0 ≤ t ≤ 30
The domain of the function is 0 ≤ t ≤ 30
Range:
The range of a function are the possible output values of the function
The range of the given function f(t) are; from approximately 7,000 feet to approximately 9,000 feet, which gives;
The range of the function: 7000 < f(t) ≤ 9,300

The points that lie on the given line are the solution of the line.
What is an equation of a line?The equation y = mx + c is the general equation of any straight line where m is the gradient of the line and c is the y -intercept.
Given is an equation of a line 2x+9y = 11, we need to find its solution,
Since, the line is an infinite object it carries an infinite solution too.
When we plot the graph of this line, all the points lying on it will be the solution of the line.
Let say x = 0,
2(0)+9y = 11
9y = 11
y = 11/9
Therefore, (0, 11/9) is the solution of the equation,
Let say x = 1
2(1) + 9y = 11
y = 1
Therefore, (1, 1) is the solution of the equation,
Please check the graph attached.
Hence, the points that lie on the given line are the solution of the line.

How is making a table of equivalent ratios to find the unit rate similar to finding the unit rate by calculating with fractions? Use a specific example to explain your reasoning.
Using specific examples, the unit rate can be obtained using equivalent ratio tables and fraction thus :
Table of equivalent ratios :
No of workers : ____ 2 ____ 4 ____ 6 ____ 8
Logs of wood cut: __ 4 ____ 8 ____12 ____16
To obtain the unit rate from the table :
Take the ratio of any pair of values ;
16/8 = 2 logs of wood
Hence, the unit rate is 2 logs of wood per worker.
Using the fractions :
2 worker = 4 logs of wood
1 worker = x
Cross multiply
2x = 4
x = 4/2
x = 2 logs of wood.
Hence, the unit rate is 2 logs of wood per worker.

how do you find the area of a circle with only the height
Answer:
in geometry, a circle is the curve that forms the boundary of a disc. Curves, like lines, have zero width and thus zero area.
For some reason, this very simple thing doesn’t seem to be taught much - I certainly recall my maths teachers referring to the area of a circle instead of the area of a disc!
As you haven’t mentioned the radius of the circle, let us consider a generic circle of radius r, thus we want to find the height of a triangle whose area is πr².

For this question the average height of adult women is 63.7” with a sigma of 2.9”. The US Navy requires that fighter pilots have heights of between 62 and 78 inches. Find the approximate percentage or women who qualify to be fighter pilots. HINT: Drawing a distribution curve may help.
Answer:
72%
Step-by-step explanation:
For this question the average height of adult women is 63.7” with a σ of 2.9”. The US Navy requires that fighter pilots have heights of between 62 and 78 inches. Find the approximate percentage or women who qualify to be fighter pilots. HINT: Drawing a distribution curve may help.
Find the z-scores.
z = (x − μ) / σ
z₁ = (62 − 63.7) / 2.9
z₁ = -0.586
z₂ = (78 − 63.7) / 2.9
z₂ = 4.93
Use a chart or calculator to find the probability.
P(-0.586 < Z < 4.93) = P(Z < 4.93) − P(Z < -0.586)
P(-0.586 < Z < 4.93) = 1.000 − 0.279
P(-0.586 < Z < 4.93) = 0.721
Approximately 72% of women will qualify.
If the Navy changes its height requirement to include all but the shortest and tallest 3% of the female population, what would the new height requirements for women be? HINT: Drawing a distribution curve may help. Also, rounding is suggested.
In this case, we work in reverse. Use a chart or calculator to find the z-score for each probability.
P(Z < z₁) = 0.03
z₁ = -1.881
P(Z > z₂) = 0.03
P(Z < z₂) = 0.97
z₂ = 1.881
Now find the heights associated with those z-scores.
z = (x − μ) / σ
-1.881 = (x₁ − 63.7) / 2.9
x₁ = 58.2
1.881 = (x₂ − 63.7) / 2.9
x₂ = 69.2
The new height requirement is between 58.2" and 69.2".

Answer:
The graph of g(x) has a lesser y intercept
Step-by-step explanation:
Given
f(x) = 100(-x + 4)
Required
Determine the relationship between f(x) and g(x)
First, we need to get the equation of g(x).
From the question, we have that:
Initial Value = 360
Rate = -90 yearly
[It is negative because the rate shows decrement]
Hence, the equation of g(x) is:
g(x) = Initial Value + Rate * x
Where x represents number of years
g(x) = 360 + (-90 * x)
g(x) = 360 - 90x
g(x) = -90x + 360
Recall that
f(x) = 100(-x + 4)
f(x) = -100x + 400
To solve y intercept, we set x = 0.
f(0) = -100 * 0 + 400 = 0 + 400 = 400
g(0) = -90 * 0 + 360 = 0 + 360 = 360
By comparison, the graph of g(x) has a lesser y intercept
To solve x intercept, we set y = 0
For f(x)
0 = -100x + 400
100x = 400
x = 4
For g(x)
0 = -90x + 360
90x = 360
x = 4
By comparison, they have the same x intercepts.

What is the circumference
Answer:
In geometry, the circumference is the perimeter of a circle or ellipse. That is, the circumference would be the arc length of the circle, as if it were opened up and straightened out to a line segment. More generally, the perimeter is the curve length around any closed figure.
Step-by-step explanation:
Answer:
1. Circumference = 87.92
2.Circumference = 43.96
Step-by-step explanation:
The first problem it had a radius. So in order to find the circumference you will have to use the formula 2πr. When you plug in the 14 yd in the radius spot it will look like 2π(14) when you solve it the answer will be 87.92
The second one has a diameter so the equation you will have to use is πd. Now you will have to plug the 14 cm where the diameter is which will look like π(14) when you solve it the answer will come out as 43.96
