Interpret the average rate of change of –14/3 that you found previously. What does this mean in terms of the waterslide, from x
Yanka [14]

Answer:

Solution: The average rate of change of  represents that the second variable is decrease by 14 if the first variable increase by 3. In terms of water slide the vertical height of slide is decreased at the rate of 4.66 per unit. The vertical height of the slide decrease 70 units from x = 0 to x = 15.

Explanation:

The rate of change shows the change in first variable with respect to change in second variable.

If the rate of chang is given by  it means second variable is decrease by 14 if the first variable increase by 3.

In the context of water slide it shows that the vertical height of slide is decreased by 14 units as we cover the distance of 3 units.

If we cover the distance from x = 0 to x = 15, it means we cover the distance of 15 units.

Let the vertical height of the slide covered from x = 0 to x =15 be y.

It means when distance increased by 15 units the height of slide decreased by y units.

So rate of change = .

It is given that the rate of change is .

Equate both equations.

Therefore, the average rate of change of  represents that the second variable is decrease by 14 if the first variable increase by 3. In terms of water slide the vertical height of slide is decreased at the rate of 4.66 per unit. The vertical height of the slide decrease 70 units from x = 0 to x = 15.

Ok this is kind of silly to ask but I have an equation 12-3x how do I get 3x in the front
lesantik [10]
As you can see there is a negative sign befor 3x. That means 3x is a negative value. Therefore, in order to place it as first left value you would take -3x and put it before +12 ( since there is no negative sign before 12, it will stay positive)

-3x+12

Hope This Helps :)

The total time T (in hours) needed to fly from New York to Los Angeles and back can be modeled by the equation below, where d is
Katena32 [7]

Answer:

Step-by-step explanation:

I understand that there are 2 problems here, that's right?

1, The total time T to fly from New York to Los Angeles:

Time= Distance/average speed

2, The problem with the race:

A) The total time for the race is:

t=\frac{0.5}{r} +\frac{22}{15r} + \frac{6}{r+5}

B) If you can swim at 2 miles per hour, that means r=2.

We replace r=2 and we will find the total time that we need like:

t=\frac{0.5}{2} +\frac{22}{15*2} + \frac{6}{2+5}= 0.25 + 0.73333+ 0.85714=1.84047

For rounding the answer: 1.84047 hours= 110 minutes
