Pls someone actually help no links or anything Choose the function whose graph is given by:
A. y = cos(1/2x)
B. y= cos(4x)
C. y = Cos(2x)
D. y = cos (1/4x)

Angel entered a triathlon (a three-part race). he swam 1 mile, rode his bike 30 miles, and ran 10 miles. how far did he go altogether? a. 11 miles b. 123 miles c. 41 miles d. 40 miles

Show your workcan a right triangle have this sides? *how to prove it without using the pythagorean theorema*

Will possibly give brainliest and a high rating. choose the linear inequality that describes the graph. the gray area represents the shaded region. 4x + y > 4 4x – y ≥ 4 4x + y < 4 4x + y ≥ 4
