I need help
I need help on finding the nonlinear

Answers

Answer:

Option A

Step-by-step explanation:

To find out if a function is nonlinear, you can graph the points in the table. If it forms a straight line, then it is linear. If it does not, then it is nonlinear.

1) Let's graph three points from Option A's table. Graph (1,3), (2,9), and (3,27) and see if you can draw a completely straight line passing through them. When you do, you will have something similar to the picture below. The line they form is not straight, therefore Option A is a nonlinear function.

If Destini runs 4 km in 18 minutes. Which proportion could be used to find how many minutes it would take her to run 16 km?

Answers

Answer: 72 minutes

Step-by-step explanation:

Ww would use direct proportion with the formula: y = kx

where y = number of minutes

x = distance

18 = 4k

k = 18/4

k = 4.5

Therefore, the number of minutes that it would take her to run 16 km would be:

y = kx

y = 4.5 × 16

y = 72 minute

On a snow day, Samantha created two snowmen in her backyard. Snowman A was
built to a height of 43 inches and Snowman B was built to a height of 33 inches. The
next day, the temperature increased and both snowmen began to melt. At sunrise,
Snowman A's height decrease by 4 inches per hour and Snowman B's height
decreased by 2 inches per hour. Let A represent the height of Snowman At hours
after sunrise and let B represent the height of Snowman Bt hours after sunrise,
Write an equation for each situation, in terms of t, and determine the interval of
time, t, when Snowman A is taller than Snowman B.

Answers

Answer: A= -4t+43

B=-2t+33

Snowman A is taller than snowman B when t < 5 hours

Step-by-step explanation:

A will be taller than B when t < 5.

Given, snowman A was built to a height of 43 inches and snowman B was built to a height of 33 inches.

We need to write an equation for each situation, in terms of t and determine the interval of time, t when Snowman A is taller than Snowman B.

What is an equation?

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Now, as the temperature increases snowman A's height decreases by 4 inches per hour.

The equation that represents this situation is A=43-4t.

As the temperature increases snowman B's height decreases by 2 inches per hour.

The equation that represents this situation is B=33-2t.

We know that A is taller than B.

That is, A>B

⇒43-4t>33-2t

⇒43-33>-2t+4t

⇒10>2t

⇒5>t or t<5

Therefore, A will be taller than B when t < 5.

Is (y=x^2) a function

Answers

Answer:

YES!

y=x² is a function.

Step-by-step explanation:

We know that a function is a relation where each input or x-value of the X set has a unique y-value or output of the Y set.

In other words, we can not have duplicated inputs as there should be only 1 output for each input.

Given the equation

y=x²

Here, for every value of x, there is a unique y-value or output.

For example,

when x = 3, y = 9, when x = 6, y = 36

In other words, it does not matter which x value of chose, there will be only output.

Therefore,

YES!

y=x² is a function.
