Use identities to find values of the sine and cosine functions of the function for the angle measurea. theta, given that cos2theta=28/53 and 0theta < theta < 90degreesb. 2theta, given sin theta= - sqrt 7 over 5 and cos theta > 0c. 2x, given tan x=2 and cos x<0

constants mean the stopped points or the points on a graph that nothing is changing, hope this

step-by-step explanation:

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.

step-by-step explanation:

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13

company a

step-by-step explanation:

using the linear regression models , it is found that company a   pays about $14 more. but using the same regression (linear) company b pays about $10 more.

so company a pays more than b
