Answer:
6 knots
Step-by-step explanation:
Let the speed be v knots
then time taken to cover 500 M = 500 / v hrs
fuel consumption /hr = 216 + 0.5v^3
let F be the fuel consumption for trip
= [500/v][216 + 0.5v^3]
= 500[216/v + 0.5v^2]
dF/dv = 500[ - 216/v^2 + v]
d^2F/d^2v = 500[432/v^3 + 1] , i.e. +ve
so setting dF/dv will give a minima
500[ -216/v^2 + v] = 0
or v = 216/v^2
or v^3 = 216
solving, we get v = [216]^(1/3) = 6 knots

Answer:
y = 4x + 24
Step-by-step explanation:
The slope is the number in front of the x-value.
Slope intercept form is in the form of
y = mx + b (or as how I learned it)
m is the slope, and b is the y-intercept (the number that is left on the side.)
You can rearrange this by moving the x to the right side by subtracting it from both sides.
You now have 1/8y = 3 - 1/2x
which can be rearranged to
1/8y = -1/2x + 3.
You need to change the y to 1 whole instead of 1/8, so you multiply it by 8 since 8 divided by 8 is 1.
y = -4x + 24
