Answer:
B
Step-by-step explanation:
Here, we want to find which of the expressions is undefined
kindly note that
sin^-1 is arcsin
cos^-1 is arccos
A. arcsin (1) = 90 degrees
B. arcsin (-2) = undefined
c. arccos 0 = 90 degrees
d. arccos (-1) = 180
Joining midpoints(a line segment MN is formed) tells you that you have a line MN that is 1/2 the length of GH
MN = 1/2 GH
MN = 1/2 (8x + 2)
13 = 1/2 (8x + 2) Multiply both sides by 2
13 * 2 = 8x + 2
26 = 8x + 2 subtract 2 from both sides.
26 - 2 = 8x
24 = 8x Divide by 8
24/8 = x
x = 3
√75 = √25*3 = 5<span>√3
the square root of 25 is 5. Therefore you bring it out of the square root and leave the 3</span>
It's 10 feet long and has a 30 foot perimeter
Answer:
Step-by-step explanation:
2x - 2 = - 200
Bringing like terms on one side
2x = - 200 + 2 = - 198
2x = - 198
x = - 198/2 = - 99
