Answer:

A=SqRt(c^2-b^2)

Step-by-step explanation:

a^2 + b^2 = c^2

rearrange to solve for a^2

a^2= c^2-b^2

take the square root of each side

a= square root (c^2-b^2)

4. Represent the ordered pairs in the mapping diagram as a set of ordered pairs and as a table.

Firlakuza [10]

Answer/Step-by-step explanation:

✔️As a set of order pairs, the mapping can be represented as (x, y), where x = input and y = output.

Thus:

{(1, 6), (2, 6), (3, 6), (4, 8)}

✔️As a table we have input as x, and y as output, such as:

x | y

1 | 6

2 | 6

3 | 6

4 | 8

kirill [66]

Answer:

His average speed was of 10.42 m/s

Step-by-step explanation:

We use the following relation to solve this question:

$v = \frac{d}{t}$

In which v is the velocity(in m/s), d is the distance(in meters), and t is the time, in seconds.

Usain Bolt of Jamaica set a world record in 2009 for the 200- meter dash with a time of 19.19 seconds.

This means that $d = 200, t = 19.19$

So his average speed was of:

$v = \frac{d}{t} = \frac{200}{19.19} = 10.42$

His average speed was of 10.42 m/s

I already know the answer to this problem, I want a explanation on how to get the answer.

$\\ \bull\tt\dashrightarrow BC=CE$

$\\ \bull\tt\dashrightarrow 3x+3y=7x+5y$

$\\ \bull\tt\dashrightarrow 7x-3x=3y-5y$

$\\ \bull\tt\dashrightarrow 4x=-2y$

$\\ \bull\tt\dashrightarrow 2x=-y$

$\\ \bull\tt\dashrightarrow \dfrac{x}{y}=\dfrac{-1}{2}$

Now

$\\ \bull\tt\dashrightarrow BE=BC+CE+CD$

$\\ \bull\tt\dashrightarrow BE=3x+3y+7x+5y+5x-2y+6$

$\\ \bull\tt\dashrightarrow BE=15x+6y+6$
