Answer:
Jennifer paid $108
Step-by-step explanation:
First you have to figure out how much Jennifer's parents paid. In order to do that you will have to do:
180 * 40 = 7,200 Then do: 7,200 / 100 which is 72 OR YOU CAN:
40 / 100 = .40 Then do : .40 * 72 which is 72
So Jennifer's parents paid $72.
So now you figured out how much Jennifer's parents paid, so to figure out how much Jennifer paid do:
180 - 72 which is $108.
This is how you know how much did Jennifer pay.
The 3 angles of a triangle, when added, = 180 degrees
so if 2 of them are 70.....70 + 70 = 140
then the 3rd will be 180 - 140 = 40 degrees <==
1. 6, 12, 18
2. 8,16,24
3. 12, 24, 36
4. 15, 30, 45, 60
4. 30, 60, 90

Answer:
A, B, E, and F
Step-by-step explanation:
sinx and cosx are defined for all values of x. So, sin⁻¹x and cos⁻¹x are also defined for all values of x.
A and E are correct.
tanx is defined for all values of x.
However, tan(nπ) = 0 at when n is an integer. So, tan⁻¹(±nx) is undefined. However, tan⁻¹(-½x) is defined, because -½ is not an integer.
B and F are correct.
C and D are <em>wrong</em>. Both sec⁻¹x and csc⁻¹x are undefined when -1 < x < 1, and -½ is in this forbidden region.
