1. the value(s) of x when sin(x) = -1 are x = -90° and 270°? true false 2. the y-value for y = cos(x) when x = -90° is 0. true false 3. what is the y-value for y = tan(x) when x = -45°? 1/2 1 -1 4. one of the x-value(s) for tan(x) = 0 is 90°. true false

1. True

2. True

3. y = -1

4. False

Step-by-step explanation:

1

sin(-90) = -1

sin(270) = -1

True

2

y = cos(-90)

y = 0

True

3

y = tan(-45)

y = -1

-1

4

tan(90) cannot be calculated

False

i would think "anyone would want the best for their child" is correct

it would be 4 over -2 divided by -1 over 3.

if you want a solution it would be 4

you flip it so it would be 4/-2 divided by 3/-1 then it would be 12/3 and you would simplify it to 4
