How to calculate the length of an arcThe formula for calculating the length of an arc is expressed as;
L = rtheta
where
r is the radius
theta is the subtended angle
Given the following
r = 7/9π

Classify each pair of labeled angles as complementary, supplementary, or neither.
Drag and drop the choices into the boxes to correctly complete the table. Each pair of angles may belong to more than one category.
Answer:
The angles 53 and 127 are supplementary.
The angles 56 and 34 are complementary.
The angles 67 and 67 are neither.
Step-by-step explanation:
Supplementary angles are two angles that add up to 180 degrees.
Complementary angles are two angles that add up to 90 degrees.
Add the angles found in each choice to get 180, 90, and 134.

1. A car is traveling down a road at a constant speed of 50 miles per hour. a. Complete the table with the amounts of time it takes the car to travel certain distances, or the distances traveled for certain amounts of time. Help please and thank you :)
By finding the linear equation that relates distance and time, we can see that the complete table is:
time (hours) distance (miles)
2 100
1.5 75
t (50)*t
1 50
6 300
d/(50) d
How to complete the table?
After a small online search, I've found that the table is:
time (hours) distance (miles)
2
1.5
t
50
300
d
Now, remember the relation:
distance = speed*time.
In this case, we know that the speed is 50 mi/h, so if we define d as the distance and t as the time, we can write:
d = (50mi/h)*t
To complete the table, we just replace the value that appears in the table, and then we solve the equation for the other variable.
First we have t = 2 hours:
d = (50 mi/h)*2h = 100 mi
Then we have t = 1.5 hours
d = (50 mi/h)*1.5 h = 75 mi
Then we assume that we evaluate in t, so there we just write the equation:
d = (50 mi/h)*t
Now we go to the other side of the table, now we evaluate d, so we can write:
t = d/(50 mi/h)
(that is what goes in the table when we need to evaluate in d).
Then the fourth place in the table has d = 50 mi, replacing that:
t = (50mi)/(50 mi/h) = 1h
And finally, we evaluate in d = 300mi
t = (300 mi)/(50 mi/h) = 6h
Then the complete table is just:
time (hours) distance (miles)
2 100
1.5 75
t (50)*t
1 50
6 300
d/(50) d

if the width of a rectangle with perimeter P is 6 units , what is the length.
Answer:
L= P/2 - 6
Step-by-step explanation:
As you know that the Perimeter of a Rectangle = 2(L+W)
since Perimeter = P and Width = 6
Then P = 2(L+6)
Expanding
P=2L+12 --> 2L=P-12
Then L=(P-12)/2=P/2-6
The perimeter is twice the sum of width and length. Then the length of the rectangle is P/2 – 6 units.
What is a rectangle?It is a polygon that has four sides. The sum of the internal angle is 360 degrees. In a rectangle, opposite sides are parallel and equal and each angle is 90 degrees. And its diagonals are also equal and intersect at the mid-point.
If the width of a rectangle with perimeter P is 6 units.
Perimeter = P
Width = 6 units
Then the length of the rectangle will be
Perimeter = 2 (Width + Length)
P = 2 (6 + L)
L = P/2 – 6
The length of the rectangle is P/2 – 6 units.

I hope this helps you:)Find the values of x, y, and z. Round to the nearest tenth, if necessary.
Answer:
Step-by-step explanation:
The value of x is 15, y is 5 and z is 17 units in the given triangle.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
First let us find value of y
We know that hypotensue / leg = leg/y
20/10 = 10/y
Apply cross multiplication
20y=100
y=5
Now let us find x value
20-y=x
20-5=x
x=15
The altitude is √5.15= √75
=8.6
Now by pythagoras theorem, we find value of z
x²+75 = z²
15²+75 = z²
225+75= z²
300= z²
z=17.3
Hence, the value of x is 15, y is 5 and z is 17 units in the given triangle.

Using the z-distribution, as we have the standard deviation for the population, it is found that the 99% confidence interval for the population mean is given by:
[tex]\overline{x} \pm 2.58\frac{s}{\sqrt{n}}[/tex]
What is a t-distribution confidence interval?The confidence interval is:

You start at (0, 8). You move down 7 units and right 8 units. Where do you end?
========================================================
Explanation:
The "move down 7" means the y coordinate 8 becomes 8-7 = 1
We subtract 7 from the y coordinate.
The "move right 8 units" means we add 8 to the x coordinate to get 0+8 = 8
Therefore, the point (0,8) moves to (8, 1)
