Answer:
The train travels 0.25 miles per gallon, the slope is 200/50 or 4/1
Step-by-step explanation:
We get this answer by dividing 50 miles by 200 gallons, allowing us to receive the ratio of 0.25 miles per gallon.
The slope is a representation of that ratio, as concluded from the graph
Hope this helps!
With reduction of order, we assume a solution of the form

, with

. Then


and substituting into the ODE gives



Let

, so that

. This gives the linear ODE

This equation is also separable, so you can write

Integrating both sides with respect to

gives


Next, solve

for

by integrating both sides again with respect to

.



And finally, solve for

.

and note that

is already taken into account as part of

, so this is the general solution to the ODE.

Answer:
Albert is 24. Albert's father is 48
Step-by-step explanation:
The circumference = 2×pi×radius
the small = 2×3.14×4 = 25.12 inches
the medium = 2×3.14×5 = 31.4 inches
the large = 2×3.14×6 = 37.68 inches
