Answer:
5 + 2i
We were given the complex numbers;
a = - 2 - 5i
and
b = - i
We want to find the product;
ab^3 ^ = Exponent
We substitute the complex numbers into the expression and simplify
( - 2 - 5i ) (i)^3 ^ = Exponent
This is rewritten as:
( - 2 - 5i) (i)^2 x i ^ = Exponent
Note that
i^2 = - 1 ^ = Exponent
We substitute to obtain:
( - 2 - 5i ) x - i
Let us expand to get:
- 2 x - i + 5i x - i
This simplifies to:
2i - 5i^2 ^ = Exponent
This gives:
2i - 5 ( - 1 ) = 2i + 5

Answer:
Step-by-step explanation:
<u>20% of juice has:</u>
- 10*0.2 = 2 cups of extract
<u>If x cups of juice added we'll have:</u>
- 2 + x*0.15 = 0.17(10 + x)
- 2 + 0.15x = 1.7 + 0.17x
- 0.17x - 0.15x = 2 - 1.7
- 0.02x = 0.3
- x = 0.3/0.02
- x = 15
Answer:solve for y
y -1/2x ≥ 4
y ≥ 1/2x + 4
The y intercept is 4, and the slope is positive, so the only graph with that conditions is B.
