Answer:
16.9 m
Step-by-step explanation:
Start with a half a circle. The central angle of a semicircle is 180 deg.
Now subtract 21 deg on each side.
180 - 21 - 21 = 138
The central angle is 138 deg.
The radius is 7 m.
Now we use the formula for the length of an arc of a circle given the radius of the circle and the central angle of the arc.
[tex] s = \dfrac{n}{360^\circ}2 \pi r [/tex]
[tex] s = \dfrac{138^\circ}{360^\circ}2(3.14159)(7~m) [/tex]
[tex] s = 16.9~m [/tex]

Jeremy drove from Portland to Miami. He determines that the expression 450x + 150 represents the distance in miles he traveled, where x is the number of days after the first day. Which statement describes correctly what the coefficient of x represents?
Answers
Answer:
The coefficient of x represents the number of miles driven each day.
Step-by-step explanation:
The coefficient of x is being multiplied by x, or the number of days. If the expression models the total distance travelled, then Jeremy drove 450 miles each day.
Rosalie and Emmet are having a disagreement. Rosalie thinks a line can have a line of symmetry, while Emmet
disagrees. What do you think: can a line have a line of symmetry? Why? Explain completely.
Answers
A line totally can have a line of symmetry. while it does not have width (therefore cannot put the line of symmetry through its "width"), it does have a length like any other shape. If we take a 4 unit line, we could put the line of symmetry at the 2 unit mark.
^sorry, im rushing a bit so you might have to paraphrase !
Answer:
Rosalie is correct, a line can have a line of symmetry.
Step-by-step explanation:
If you draw a line, a line of symmetry to that line would be perpendicular to the original line. Because lines are straight, they have an infinite number of lines of symmetry.

The graph that is made up of two straight lines, which has an absolute maximum or absolute minimum, and is symmetric belongs to the
function family.
Answers
Answer:
This may be a function of the absolte value family.
f(x) = IxI.
f(x) = x if x ≥ 0
f(x) = -x if x ≤ 0
Where this is the parent function, and the graph is shown below in green.
If the coefficient is positive, then the lines open upwards, and we will have a minimum (in this case, when x = 0).
And also in this case, we have symmetry around the value x = 0.
Now, the vertex can also be an absolute maximum if the coefficient is negative, like in the example shown below in color blue (the equation for the blue graph is f(x) = -3*IxI )
4. Describe the following graph completely
a. Where is the vertex of the parabola?
b. Is there a line of symmetry? If so, draw it in.
c. Are there any x-intercepts? If so, name them. d. Are there any y-intercepts? If so, name them.

What is the value if the y-intercept of a line that passes through the points (3,-2) and has a slope of 4
Answers
Answer:
the y-intercept is -14
Step-by-step explanation:
To get the y intercept, you need to get the b from y = mx + b
y - y₁ = m (x - x₁)
m = 4
(x₁,y₁) = (3,-2)
y - (-2) = (4) (x - (3))
y + 2 = 4x - 12
y + 2 - 2 = 4x - 12 - 2
y = 4x - 14
y = mx + b
b = -14

Find the equation of the line that passes through the point (1,2) with a slope of 4. Plug in your values for a and b into the equation below.
y = ______x+_______
Answers
Answer:
y=4x-2
you can find the y intercept if you plot a confirmed point on a graph and follow the slope to the line.
Answer:
y = 4x - 2
Step-by-step explanation:
Since we are given the slope already, we can solve for the y-intercept using the slope, the given point, and the formula [ y = mx + b ]
y = 4x + b
2 = 4(1) + b
2 = 4 + b
-2 = b
Substitute with what we solved for into the formula.
y = 4x - 2

What is the hypotenuse of a right triangle if the legs are each 20 inches long? Round to the nearest whole number. A. 28 B. 29 C. 30 D. 31
Answers
Answer:
The answer is A.
Step-by-step explanation:
You have to apply Pythagoras Theorem :
[tex] {c}^{2} = {a}^{2} + {b}^{2} [/tex]
[tex]let \: a = 20,b = 20[/tex]
[tex] {c}^{2} = {20}^{2} + {20}^{2} [/tex]
[tex] {c}^{2} = 800[/tex]
[tex]c = \sqrt{800} [/tex]
[tex]c = 28 \: (nearest \: whole \: no.)[/tex]
P.S (Take note):
Pythagoras Theorem can only applied in right angle triangle.
Answer:
We can find the hypotenuse by using the Pythagoras theorem/theory. The Pythagoras theorem states that,
[tex]h^{2}[/tex] = [tex]p^{2}[/tex] + [tex]b^{2}[/tex] where, h = hypotenuse, p = perpendicular, b = base
=> [tex]h^{2}[/tex] = [tex]20^{2}[/tex] + [tex]20^{2}[/tex]
=> [tex]h^{2}[/tex] = 400 + 400
=> [tex]h^{2}[/tex] = 800
=> h = [tex]\sqrt{800}[/tex]
=> h = 28.284.....
Therefore rounded to the nearest whole number, we get,
h = 28
