Mathematics

Solve the problem.The city park district is planning on sodding the outfield of the little league baseball field. Thedistance from home plate to the outer edge of the infield is 70.00 ft. The angle between the outer edge of the first and third baselines is 90°, and the radius of the sector is 315.0 ft. Determine the area of the outfield.

A. 306,800 ft2 B. 4,460,000 ft2 C. 77,930 ft2 D. 73,030 ft2

Decide whether or not the points are the vertices of a right triangle.(-7, -1), (1, -1), (1, 4)

A. Yes B. No

Find a, b, and h so that f(x) ? a sin (b(x - h)). Round to two decimal places if necessary.f(x) = 4 sin 3x - 2 cos 3x

A. a = 0.15, b = 3, h = 4.47 B. a = 4.47, b = 3, h = 0.15 C. a = 4.47, b = 6, h = 0.15 D. a = 6.00, b = 2, h = 0.63

Use your graphing calculator to determine if the equation appears to be an identity or not by graphing the left expression and right expression together. ? ?

A. not an identity B. is an identity
