Answer:
-3 or decreasing by 3
Step-by-step explanation:
To find the average change, you only care about the first and last point which would be (3,17) and (8,2)
the overall change during that time is 2-17=-15 (for the f(x) side )
the overall change during that time is 8-3=5(for the x side)
all we have to do is -15/5=-3
therefore the average rate of change is -3
Displacement(d)=0.2m
Time taken(t)= 30 s(1min=60 s)
Velocity (v)=?
We know that,
Velocity (v) = d/t
=0.0067
Answer:
It takes the Dolphin 2 hours for swimming 40 miles. The penguin takes 8 hours and the swordfish will take 2/3 of an hour, which is 40 minutes to travel 40 miles.
Step-by-step explanation:
Given :
The bottlenose dolphin travels 40 miles in 2 hours. Or it takes 20 miles in 1 hour.
Now, dividing the distance by unit rate given in the question:
40/20=2 hours
40/5=8 hours
40÷60= 2/3 hour
Therefore,
- the dolphin takes 2 hours for swimming 40 miles.
- the penguin takes 8 hours
- the swordfish takes 2/3 rd of an hour

Answer:
A) -10°F
Step-by-step explanation:
Given that:
Boiling point of water gets affected when there is a change in the elevation.
Expression to represent the temperature i.e. boiling point w.r.to altitude
is given by the equation:
Temperature in
= 
Given that, the altitude,
= 5,000 feet
To find:
The number of degrees Farenhite at which the boiling point of water will change.
Solution:
Here, we are given the expression:
Temperature in
= 
And value of altitude,
= 5,000 feet
Let us put the value of
in the equation and let us find the value of temperature in
.
Temperature in
=

Therefore, the answer is:
A) -10°F
