Answer:
b = -1/10.
Step-by-step explanation:
(2i/2+i)-(3i/3+i)
= 2i(3 + i) - 3i(2 + i) / (2 + i)(3 + i)
= 6i + 2i^2 - 6i - 3i^2 / (2 + i)(3 + i)
= (-2 + 3) / (6 + 5i - 1)
= 1 / (5 + 5i)
Now we multiply top and bottom by 5 - 5i :
= 5 - 5i / (5 + 5i)(5 - 5i)
= 5 - 5i / 25 -25i^2
= 5 - 5i / 50
= 1/10 - 1/10i
This isn't to diffuclt. So, to the formula for the area of a circle is
, or instead of r, you can put D, which is r times 2
The diameteris 2.5, so, the answer would be
pi times 2.5, where pie = 3.14
So, the answer is 2.5 * 3.14 = 7.85 or 7.9
Answer:
Step-by-step explanation:
<u>We know that </u>
<u>We also know that </u>
<u>Since 5! = 1*2*3*4*5 is divisible by 15:</u>
- any n! with n ≥ 5 is divisible by 15.
We need to find the remainder when 1! + 2! + 3! + 4! is divided by 15 as all the rest are divisible by 15.
<u>The sum is:</u>
- 1! + 2! + 3! + 4! = 1 + 2 + 6 + 24 = 33
<u>The remainder is:</u>
As we see the remainder is 3
