Answer: Using the unit circle, the sine of an angle t equals the y-value of the endpoint on the unit circle of an arc of length t whereas the cosine of an angle t equals the x-value of the endpoint. The sine and cosine values are most directly determined when the corresponding point on the unit circle falls on an axis.

Answer:
The equation is:
y = -15*x + 1200
and:
a = 120
b = 70
c = -1500
Step-by-step explanation:
This seems to be a linear relationship.
A linear relationship can be written as:
y = a*x + b
where a is the slope and b is the y-axis intercept.
For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:
a = (y2 - y1)/(x2 - x1).
Here we know that our line passes through the points (60, 300) and (20, 900)
Then the slope of this line is:
a = (900 - 300)/(20 - 60) = 600/(-40) = -15
Then this line is something like:
y = -15*x + b
To find the value of b, we know that this line passes through the point (60, 300) then when x = 60, we have y = 300.
Replacing these values in the above equation we get:
300 = -15*60 + b
300 + 15*60 = b = 1200
Then:
y = -15*x + 1200.
Now that we have this equation, we can complete the table.
a is the value for y, when x = 72
Then we can replace x by 72 in the above equation:
a = -15*72 + 1200 = 120
a = 120
b is the value of x when y = 150, then we need to replace y by 150
150 = -15*b + 1200
150 - 1200 = -15*b
(150 - 1200)/-15 = b = 70
then:
b = 70
c is the value of y when x = 180, then we need to replace x by 180.
c = -15*180 + 1200
c = -1500

Lines c and d are perpendicular. The equation of line c is y=−12x+1. What is the equation of line d?
Answer:
y=1/12x+b
Step-by-step explanation:
To find a perpendicular line, you need to find the negative reciprocal of the gradient in this case its -12x, the negative reciprocal of this is 1/12x we don't know what coordinates this passes through so we just write y=1/12x+b

If the box is full, and the length and height of the box are `5/7` and `1(1)/(2)` feet, respectively, what is the width of the box? A. `1/2` foot B. `1/7` foot C. `3/5` foot D. `4/7` foot
Answer:
A. `1/2` foot
Step-by-step explanation:
The computation of the width of the box is shown below:
15 ÷ 28 = (5 ÷ 7)(1 1 ÷ 2)(width)
15 ÷ 28 = (5 ÷ 7)(3 ÷ 2)width
15 ÷ 28 = (15 ÷ 14)width
(15 ÷ 28) ÷ (15 ÷ 14) = width
(15 ÷ 28) × (14 ÷ 15) = width
w = 14 ÷ 28
= 1 ÷ 2 ft

Answer:
y = 5x + 10
Step-by-step explanation:
Line is passing through the points (2, 20) & (4, 30)
Slope of line (m) = (30 - 20)/ (4 - 2) = 10/2 = 5
y - 20 = 5(x - 2)
y = 5x - 10 + 20
y = 5x + 10

Answer:

Step-by-step explanation:
1. Make a fraction with the total number of cards at the bottom (60) and all the cards that are not green (aka yellow and blue) on top (42). Then simplify the fraction 42/60 by dividing both terms by 6 to get 7/10
2. For this one, first find how many students out of the first 80 liked basketball by subtracting the 60 students who liked other sports from 80. This gives you 20. Now you know that 20/80 students like basketball. Now simplify the fraction to get 1/4. Then find 1/4 of 100, because we know that 1/4 of students like basketball. 1/4 of 100 is 25.
3. This problem is exactly the same as number 1, except instead of adding all the other colors and putting them as a fraction over the total, just put the number of pink shirts over the total number of shirts to get 3/12. Then simplify it to 1/4, and that's your answer.
4. This is also similar to problems 1 and 3. Just put the number of heads coin tosses over the total and simplify it.
5. This one is very similar to all the problems so far. I will let you do this one on your own. Remember: The number of cases (rolls or colors or sports or cards etc.) that you want to find the probability for goes on top, and the total number of those things goes on the bottom. The bigger the fraction, the greater probability there is.
Note: Please only ask one question at a time on here instead of 5 at once. Since these problems are so similar, chances are, you could have figured them out on your own with a little help on one of them. You are more likely to get a quick answer if the answerer doesn't have to do as much work.

Answer:
a) y = 4x - 2b) y = 3x + 2c) y = 2x - 6Step-by-step explanation:
a)
The slope as per two ordered pairs (-2, -10), (0, -2)
m = (-2 - (-10))/(0 - (-2)) = 8/2 = 4The y-intercept is -2
The equation for this function:
y = 4x - 2b)
The slope is
m = 3The line passes through (1, 5)
The line is:
y - 5 = 3( x - 1) in point-slope formy = 3x +2 in slope-intercept formc)
The slope as per points on the graph (3, 0), (4, 2)
m = (2 - 0)/(4 - 3) = 2The line in point slope form using point (3, 0):
y = 2(x - 3)The line in slope-intercept form:
y = 2x - 6a) substitute m = 4 and c = - 2 into the slope intercept equation, thus, the equation of the line is y = 4x - 2
The answer is y = 4x - 2
b) Let's begin by listing out the given information:
The line has a slope of 3
The equation of the line becomes:
[tex]y = mx + b \\ m = 3 \\ y = 3x + b[/tex]
The line passes through point (1, 5).
We will obtain the equation using the point-slope formula, we have:
[tex]y - y1 = m(x - x1) \\ (x1 \: y1) = (1 \: 5) \\ y - 5 = 3(x - 1) \\ y - 5 = 3x - 3 \\ y = 3x - 3 + 5 \\ y = 3x + 2[/tex]
Therefore, the equation of the straight line is y = 3x + 2
c) we use that point and the slope to replace in the expression:
[tex]y - y1 = m(x - x1)[/tex]
That is:
[tex]y - 0 = 2(x - 3) \: \: y = 2x - 6[/tex]
y = 2x - 6 is the answer

find the value of x .
Answer:
49.79
Step-by-step explanation:
Using SOH CAH TOA;
Le the height be h
Tan 70 = h/16
h = 16tan70
Get the value of x
Opposite = 16tan70
hypotenuse = x
sin 62 = 16tan70/x
x = 16sin70/sin62
x = 16(2.7475)/0.8829
x = 43.96/0.8829
x = 49.79
Hence the value of x is 49.79
