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.
Approximately 1.143 L of peroxide should be added to the original solution.
Answer:
19/20
Step-by-step explanation:
7/10+1/4
=14/20+5/20
=19/20
You have to do 5/6 of 8
first 8÷6=1.3 (or remainder 3)
1.3×5=6.5
So that means Alonzo will need 6.5m at least amount of fabric.
Hope this helped! :)
Step-by-step explanation:
6.5 / 0.5
= 6.5 / (1/2)
= 6.5 * (2/1)
= 13.
Since 13 is unequal to 3.25,
we conclude 6.5 / 0.5 = 3.25 is false.
