Answer:
Step-by-step explanation:
Joint variation has the equation
y = kxz
k is the constant of variation and needs to be solved for using the initial conditions, then filled in later to another equation related to the given info to solve for something else. We are given y = amount of oil used, x = distance traveled, z-squared is the speed. Our equation looks like this, to be exact:

Filling in with the initial conditions:
which gives us the
k = .0014166667
Now we need to find the amount of oil used, y, under other circumstances, but this time we have our k.

which gives us that the amount of oil used, when rounded to the tenths,
y = 24.0 barrels
Your answer would be 63.33. ((: ❤️
Answer:

Step-by-step explanation:
To solve this, we are using the average rate of change formula:

where
is the average rate of change
is the first point
is the second point
is the function evaluated at the first point
is the function evaluated at the second point
We want to know the average rate of change of the function
form x = -3 to x = 0, so our first point is -3 and our second point is 0. In other words,
and
.
Replacing values







We can conclude that the average rate of change of the exponential equation form x = -3 to x = 0 is 
Answer:
D. 4 23/24
Step-by-step explanation:
1 7/8 = 1 21/24
6 5/6 = 6 20/24
6 - 1 = 5
20 - 21 = -1
5 - 1/24 = 4 23/24
Answer:
Equivalent fractions are fractions that have the same value or amount even if they seem different. They are a type of fraction that are equivalent in nature.
Step-by-step explanation:
Equivalent means being equal in value, function, amount or meaning. Even if they seem different they are the same in their own way (and I'm talking about fractions now)
