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.

Likurg_2 [28]

Answer:

  242/27

Step-by-step explanation:

Using the formula for the sum, you can fill in the given values and do the arithmetic.

  Sn = a1·(r^n -1)/(r -1)

  S5 = 6·((1/3)^5 -1)/(1/3 -1) = 6(-242/243)/(-2/3) = 6·(121/81)

  S5 = 242/27

_____

Or, you can write the terms and add them up. The sum is ...

  6 + 2 + 2/3 + 2/9 + 2/27 = (162 +54 +18 +6 +2)/27 = 242/27

balu736 [363]

Answer:

m=5

Step-by-step explanation:

5m-3=22

  1. take 3 the other side by doing the opposite operation

5m= 22+3

5m= 25

  • then divide it by 5 on both sides to get the value of m.
  • 5m÷5=25÷5
  • 5and 5 cancels out and the answer becomes :

PLEASE HELP!! Use complete sentences to explain how to use linear factors to determine the equation of a polynomial function.
denis-greek [22]
 If x 1 and x 2 are the roots of quadratic polynomial of a x 2 + b x = c (i.e.the root of equation of a x 2 + b x + c = 0 ), then a x 2 + b x + c = a ( x − x 1 ) ( x − x 2 ) .This is the formula of factoring quadratic polynomial into factors
