Part A:  In (0,4) and (1,8), as x increases from 0 to 1, y increases from 4 to 8.  The slope of the line connecting these 2 pts. is (8-4) / (1-0), or 4.  Now do the same thing for the 2 pts (1,8) and (2, 10).  You will find that the slope in the 2nd case is different.  Thus, the 3 given pts do NOT lie on a straight line.  Function is non-linear.

Part B:  an example of a non-linear function would be y = 2x^2 - 5.  You can tell immediately from that exponent, 2, that this function is non linear.

An ex. of a linear function would include x to the 1st power only:  y = 3x - 7.

A campground has cabins that can each hold 28 campers there are 148 campers visiting the campground.how many cabins are full if
Rainbow [258]

For this case, the first thing we must do is define variables.

We have then:

x: number of cabins

y: number of campers

We now write the equation that models the problem:

y = 28x

We know that there are 148 campers.

Therefore, substituting y = 148 in the given equation we have:

148 = 28x

From here, we clear the value of x:

x = \frac{148}{28}\\x = 5.29

Therefore, the number of full cabins is:

x = 5

Answer:

The number of full cabins is:

x = 5

Which would be the best name for a function that takes the time of day and returns the numbers of coffee sold at a coffee shop?
konstantin123 [22]

Answer:

Coffee(time)

Step-by-step explanation:

A function's output variable will be:

output(input)

So we need to find the input variable and the output variable.

We know that when the time of day changes, we get a certain amount of coffee sold. This means that the amount of coffee sold is directly influenced by the time of day.

The time of day then becomes our input as the coffee sold relies on that number.

That leaves coffee sold as our output!

So the best name for a function in this scenario is Coffee(time).

Hope this helped!

The distance between itahari and Damak is
Ludmilka [50]

Answer:

8 km by motorbike.

Step-by-step explanation:

The distance between itahari and Damak is  42 km.

Mr. Dhamala travelled 18.325 km by a  bus / 15.675 km by a taxi and the remaining distance by a motorbike.

Let he covered x distance by motorbike. So,

Remaining distance = Total distance -(distance covered by bus + distance by taxi)

= 42 -(18.325 +15.675 )

= 42-34

= 8 km

So, he travelled 8 km by motorbike.
