If
Bas_tet [7]

Answer:

5 + 2i

Step-by-step explanation:

We were given the complex numbers;

a =  - 2 - 5i

and

b =  - i

We want to find the product;

a {b}^{3}

We substitute the complex numbers into the expression and simplify:

( - 2 - 5i)( {i)}^{3}

This is rewritten as:

( - 2 - 5i)( {i)}^{2}  \times i

Note that

{i}^{2}  =  - 1

We substitute to obtain:

( - 2 - 5i)  \times - iLet us expand to get:

- 2 \times  - i + 5i \times  - i

This simplifies to:

2i - 5 {i}^{2}

This gives:

2i - 5( - 1) = 2i + 5

Kiana's soccer team's ratio of wins to losses is 5:3. Her team has played 24 games. How many games have they won?​
Bas_tet [7]

The win-to-loss ratio of 5:3 is a "part-to-part" ratio, so we can represent each part as a fraction of the whole. We can do this by simply adding 3 + 5 = 8 (the "whole") and dividing by that total. This gives us a ratio of Images, which means that the Bombers won Images of their games and lost Images of them. Since they played a total of 120 games, they won Images games and lost Images games.
