Asine curve is periodic. what does this mean?

a. the curve goes through one cycle and starts over

b. there is no pattern

c. the amplitude stays the same

d. one period equals 180 degrees

Is the point (0, 8) on the x-axis or y-axis? how do you know?

The sum of the first eight terms of an arithmetic progression is 9m + 14. the fifth term of the06 progression is 2m - 6, where m is a constant.given that the first term of the progression is 26,find the value of the common difference, d and thevalue of m.

Lines b and c are parallel. what is the measure of 2? m2 = 31° m2 = 50° m2 = 120° m2 = 130°
