Which relations are functions? List the relation number(s) that are function(s) in the answer bank

Sergeu [11.5K]

Answer:

options 1,3,4 are functions.

Step-by-step explanation:

RULE: a relation is said to be a function if every element in the domain ( the numbers in the left side in the below sets) is related to only one number ( number on the right side in the below sets).

Let us check each option one by one:

1. 3 2

9 1

-4 7

0 -2

here each number on the left side is mapped to or is related to one number only.

so this relation is a function

2. 7 1

-5 2,3

1 0

here, "-5" is mapped to two different numbers. so this relation is not a function.

3. -2 -4

2 4

6 8

-6 -8

here each number on the left side is mapped to or is related to one number only.

so this relation is a function

4. 1 3

-1 3

2 3

-2 3

here each number on the left side is mapped to or is related to one number only.

so this relation is a function.

even if it is related to the same number, it doesn't matter.

it should follow the above given rule that's it.

A building 190 feet tall casts a 90 foot long shadow. if a person stands at the end of the shadow and looks up to the top of the

Ivahew [28]

Answer:

About 64.65 degrees

Step-by-step explanation:

$\tan(x) = \frac{190}{90}$

$x = { \tan}^{ - 1} \frac{190}{90} = 64.65$

Make sure your calculator is in degree mode.

Which conic's equation has 2 squares with the same signs and different leading coefficients?

Romashka [77]

We want to see which is the conic equation that has 2 squares with the same sign and different leading coefficients.

We will see that it is the equation of the ellipse.

Now let's see why that is the correct answer.

The general conic equation is of the form:

$A*(x - a)^2 + B*(x - b)^2 = R^2$

Where A and B are the leading coefficients, (a, b) is the center of the figure, and R is the average radius of the figure.

For example, if A = B, this would be the equation of a circle, but we must have two different leading coefficients.

If we write:

A = 1/C

B = 1/K

(both are positive, because "it has two squares with the same signs").

Then we get the equation:

$\frac{ (x - a)^2}{C} + \frac{(x - b)^2}{K} = R^2$

We get the equation we wanted.

The same sign in both square parts and different leading coefficients.

The above equation is the general equation of an ellipse.

hodyreva [135]

Here we can see that the problem gives us the length of a sandwich of x = 1.2. The problem also asks us for the expression that better represents the approximate length of the crust given among the options above. Here we simply have to substitute x to each of the choices.

The answer is B) x = 8x² + 34; 45.52 centemiters

I hope it helps, Regards.
