Answer:
B: 13
Step-by-step explanation:
we are given two points as
(2, - 12) and (-11, - 12)
so,


now, we can use distance formula

now, we can plug values



So,
The distance is 13
You were right, A is 7/8.
Answer:
19
Step-by-step explanation:
He can make 2 pies with one cup of sugar so he can make 40 pies with 20 cups of sugar. He already used a cup of sugar so the total is 19 (20-1)
(1 + i)/(1 + 2i)
To simplify this, we need to multiply both sides by the conjugate.
(1 + i)(1 - 2i)
1 - 2i - i - 3i^2
Combine like terms.
3i^2 - 3i + 1
i^2 = -1
-3i - 2 is the simplified numerator.
(1 + 2i)(1 - 2i)
1 - 2i + 2i - 4i^2
1 - 4i^2
i^2 = -2
1 + 4
5
<h3><u>The simplified expression is ((-3i)/5) + ((-2)/5)</u></h3>
Answer:
2.68
Step-by-step explanation:
5 - 2.32
can be written as
5.00 - 2.32
so write that in verticle format and solve using carry-over subtraction
5.00
- 2.32
______
2.68
