Answer:

-10 -4i

Step-by-step explanation:

To subtract complex numbers, subtract the real parts.

-3 -7 = -10

and then the complex parts.

5i-9i = -4i


(-3 + 5i) - (7 + 9i) = -10 -4i

In the triangle below, the value of a is 12.6.<br><br> True<br><br> False
aev [14]

Answer:

True

Step-by-step explanation:

Formula

Tan(x) = opposite / adjacent

Givens

x = 42

adjacent = 14

opposite = ?

Solution

Tan(42) = opp/14                     Find tan(42)

Tan(42) = 0.900404

0.900404 = opp/ 14                Multiply both sides by 14

14 * 0.900404 = opp/14 * 14   Simplify the left

12.6 rounded  = opp

a = 12.6

If you take 2 1/2 tablets of meds 3 times a day for 10 days, how many tablets in total have you taken?
Alisiya [41]
This is how I solved it.
2.5 multiplied by 3 is 7.5, which equals how many she takes a day.
Then I multiplied 7.5 by 10 = 75. I did that because the meds are taken for 10 days. 
Also if you added 7.5 ten times is also 75.

So my final answer is that 75 tablets have been taken in total.
