Answer:

Step-by-step explanation:



= 
Well the radian is the measure of the radius
this line measure is then ligned up to the circumference
mearuse of 1 raidan is always equal to the measure of the radius therfor the true statements are
ratio of arc legnth to r is always equal to 1
I'm not sure what 'if the measure of is'
but I think the answer is
if the measure of is 1 radis, than the arc legnth is r since r reaprensents radius
so first and third choice are correct
Answer:
401 miles
Step-by-step explanation:
6y²+2xy+2x
Step-by-step explanation:
8y²-2y²=6y²
7xy-5xy= 2xy
2x=2x
X(3, -1) → x = 3, y = -1
x - no change
y:
calculate the distance between X and y = 1
1 - (-1) = 1 + 1 = 2
calculate the value of y in coordinates of X':
1 + 2 = 3
Answer: (3, 3)
