It was difficult to see the grid lines but i believe it is a reflection across the y-axis and a translation of (2,-7). Ry-axis T(2,-7)
Answer:
96
Step-by-step explanation:
IT IS CONVENTIONAL to let the letter s symbolize the length of an arc, which is called arc length. We say in geometry that an arc "subtends" an angle θ; literally, "stretches under."
Now the circumference of a circle is an arc length. And the ratio of the circumference to the diameter is the basis of radian measure. That ratio is the definition of π.
π = C
D .
Since D = 2r, then
π = C
2r
or,
C
r = 2π .
arc lengthThat ratio -- 2π -- of the circumference of a circle to the radius, is called the radian measure of 1 revolution, which are four right angles at the center. The circumference subtends those four right angles.
arc length
Radian measure of θ = s
r
Thus the radian measure is based on ratios -- numbers -- that are actually found in the circle. The radian measure is a real number that indicates the ratio of a curved line to a straight, of an arc to the radius. For, the ratio of s to r does determine a unique central angle θ.
Iva got the correct answer and Lorraine's answer was incorrect. Lorraine did everything correct except 1 common mistake at the end. At the end of the problem, you have the equation 2x = 20. Instead of dividing by 2, it's possible that Lorraine mixed up the steps and divided by 10 on both sides to get x = 2. You're supposed to divide 2x by 2 and 20 by 2 to get a quotient of 10.
