Multiply (9-4i)(2+5i)

Tanzania [10]

(9 - 4i)(2 + 5i)

To solve this question you must FOIL (First, Outside, Inside, Last) like so

First:

(9 - 4i)(2 + 5i)

9 * 2

Outside:

(9 - 4i)(2 + 5i)

9 * 5i

45i

Inside:

(9 - 4i)(2 + 5i)

-4i * 2

-8i

Last:

(9 - 4i)(2 + 5i)

-4i * 5i

-20i²

Now combine all the products of the FOIL together like so...

18 + 45i - 8i - 20i²

***Note that i² = -1; In this case that means -20i² = 20

18 + 45i - 8i + 20

Combine like terms:

38 - 37i

^^^This is your answer

Hope this helped!

A building 64 ft high casts a 288-ft shadow. Sarah casts a 18-ft shadow. The triangle formed by the building and its shadow is s

Anastaziya [24]

Answer:

The answer to your question is 4 ft

Step-by-step explanation:

Data

Building's shadow = 288 ft

Building's high = 64 ft

Sarah's shadow = 18 ft

Sarah's height = ?

Process

1.- Use proportions to solve this problem

$\frac{Sarah's height}{Sarah's shadow} = \frac{building's height's}{building's shadow}$

2.- Solve for Sarah's height

$Sarah's height = \frac{Sarah's shadow x building's height}{building shadow}$

3.- Substitution

$Sarah's height = \frac{18 x 64}{288}$

4.- Simplification

$Sarah's height = \frac{1152}{288}$

5.- Result

Sarah's height = 4 ft
