What is the constant of variation, k,

2 answers:

The K-constant variation is the factor of the increase-decrease relationship between the x-variable and y-variable which can be stated as y=k*x or x=y/k. For example, if y variable equal 5 and the x variable equal 2 then the k-constant variation equal 2 (calculation y=k*x --> 5=2*2.5). This constant shows the relationship between the variables.

Given two variable which are either directly proportional to each other or inversely proportional to each other, the constant of variation k is the number that relates these two variables

you make two cylinders using 8.5-by-11-inch pieces of paper. One has a height of 8.5 inches, and the other has a height of 11 in

Elan Coil [88]

The second cylinder is taller correct?
8 in < 11 in

If the height is also larger, the base is most likely larger too.

Wouldn't the largest cylinder have a Larger surface area?

Linda and Imani are each traveling in a car to the beach. Linda’s travel is modeled by a table. Imanis travel it modeled by grap

tino4ka555 [31]

Answer:

Imani traveled faster because her distance surpassed Linda's distance after the fourth hour.

Step-by-step explanation:

1. Understand the slope:

Ok, so the slope basically tells us how fast Imani and Linda traveled, so if we solve for the slope we know how fast Imani and Linda traveled.

2. Find Linda's slope:

- Take any two points: (0,10) and (1, 65).

Slope = (y1 - y2)/(x1 - x2)

= (65-10)/(1-0)

= 55

Since the slope is 55, we know her speed is 55 miles per hour.

2. Find Imani's slope:

- Take any two points: (0,0) and (1, 60).

Slope = (y1 - y2)/(x1 - x2)

= (60-0)/(1-0)

= 60

Since the slope is 60, we know her speed is 60 miles per hour.

3. Compare: Since 60>55, we know Imani traveled faster. If we look at options, we can see there's only one answer which shows that Imani traveled faster, so that must be the answer.

Next year the cost of gasoline will increase $1.25 from the current price. If the cost of a gallon

ahrayia [7]

Answer:

3.25

Step-by-step explanation:

Cost will increase by 1.25$

So it will be 4.50$

Which means that in order to know how much the current price of gasoline is, we need to subtract:

4.50-1.25=3.25$

So the current cost of gasoline is 3.25$
