Answer:

Step-by-step explanation:

Well a relation is a set of points and a function is a relation where every x value corresponds to only 1 y value.

So lets see which x values in these relations have only 1 y value.

A. Well a isn’t a function because the number 3 which is a x value had two y values which are -1 and 4.

B. This relation is a function because there are no similar x values.

C. This is not a function because the x value 4 has two y values which are 4 and -3.

D. This is not a function because the number 1 has 2 and 3 as y values.

What is the value of tan x°?

dmitriy555 [2]

Hi there!

$\tan(x) = \frac{opposite \: side}{adjecent \: side}$
$\tan(x) = \frac{8}{6}$
$\tan(x) = 1 \frac{1}{3}$

$x = 53.1$
Therefore tan x° = 1 1/3 and x = 53.1°

Therefore, 37/50 of the animals in the shelter are dogs.

Step-by-step explanation:

Given

Given that 74% of the animals at an animal shelter are dogs.

To determine:

About what fraction of the animals at the shelter are dogs?

Using the equation to find a fraction equivalent to 74%

$\:74\%=\:\frac{74}{100}$

Divide numerator and denominator by 2

$=\frac{\frac{74}{2}}{\frac{100}{2}}\:\:$

Cancel the common factor 2.

$=\frac{37}{50}$

Thus, 37/50 is the equivalent fraction to 74/100.

Therefore, 37/50 of the animals in the shelter are dogs.
