The formula for the circumference c of a circle, in terms of the radius, is c=2πr, where r stands for the radius. rearrange the quantities in this formula to give a new formula for the radius of a circle in terms of the circumference. a. r= 2c/3.14 b. r=3.14/2c c. r=c/2(3.14) d. r= 1/2(3.14)c

answer: a and c are correct

step-by-step explanation:

the +5 is the vertical translation

the added negative symbol in front is the reflection over the y-axis

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.
