Answer:
35/37
Step-by-step explanation:
In this question, we are to calculate the ratio that represents the cosine of angle O
Firstly, please check attachment for diagram of the triangle.
Mathematically, the trigonometric term Cos means the ratio of the length of the adjacent to that of the hypotenuse
The hypotenuse is the longest length which is 37 which represents the length ON
The side adjacent to angle O is the side OP which is 35
Thus, the ratio representing the cosine of angle O is 35/37
The answer is x=y.
You'll see if you replace all the x's with y's.
The slope intercept form is 
Explanation:
The equation is 
Now, we shall bring the equation
in the slope intercept form.
The general form of the slope intercept is given by

Hence, we need to rewrite the given equation in this form.
Thus, we have,

Subtracting both sides of the equation by 5x, we get,

Multiplying both sides of the equation by (-), we get,

Thus, the slope intercept form of the given equation is 
1. Need distance formula to find how long it is then cut it in half to find the radius....d= 10.....r= 5
Need midpoint formula to find the center....midpoint= (-1, -1)
(h,k) in the equation of a circle is the center, "r" is the radius. When you plug in the center, you have to put the opposite signs...so......
equation of a Circle = (x - h)^2 + (y - k)^2 = r^2 = (x + 1)^2 + (y + 1)^2= 25
2. A= pi(r^2)
200.96= 3.14(r^2)
64 = r^2
r = 8
Then to find the circumference, C= 2(pi)(r) = 2 (3.14) (8) = 50.24
For 3 and 4, is there a diagram?
A quilt design uses parallelogram-shaped pieces that have a base measure of 4 inches and a height of 6 inches. If 15 pieces are used in the quilt, what is the total area of the parallelogram-shaped pieces in the quilt?
1.225 in.
2.360 in.
3.(450 in.)
4.900 in.
<span> 15*4*6 = 360 sorry but I only have the answers for number 1 and 2
