Margo can purchase tile at a store for $0.99 per tile and rent a tile saw for $18. At another store she can borrow the tile saw
Margarita [4]
(0.99x) + 18 = 1.19x

18 = 1.19x
      - 0.99x

18 = 0.2x

18/0.2 = x

90 = x
(She must by 90 tiles for the cost at both stores to be the same, Cheers!)

Evaluate the inverse trigonometric function Sin^-1(-1). Give answers in both radians and degrees.
grin007 [14]

Answer:

B) Sin^-1(-1) = 3pi/2 or 270°

D) Sin^-1(-1) = -pi/2 or -90°

Step-by-step explanation:

Sine function:

The sine function is -1 at 270º(-90º), which is 3pi/2 = -pi/2.

Inverse sine:

The input of the inverse sine function is a value, and the output are the angles which have the sine equal to the input.

Sin^-1(-1)

Angles for which the sine are -1, that is 3pi/2 or 270° and -pi/2 or -90°. Thus, options B and D are correct.
