Which expression is equivalent to (sin x + 1)(sin x − 1)?

Keep in Mind the trigonometric Identity to solve the problem

sin²x+cos²x=1

cos²x= 1 - sin²x

Now, (Sin x -1)× (Sin x +1)

= (Sin²x-1²)→→→Used the Identity, (a-b)(a+b)=(a²-b²)

= Sin²x-1

= - (1-sin²x)

= -Cos²x

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )

.24

step-by-step explanation:

the probability is   .24

the first player had the highest probability of getting a silver marble

the game could be made fair by adding back the marble that was drawn after each draw
