Two hot air balloons are traveling along the same path away from a town,
emmainna [20.7K]

Answer:

Henry's balloon was farther from the town at the beginning and Henry's balloon traveled more quickly.

Step-by-step explanation:

The distance of Tasha's balloon from the town is represented by the function y = 8x+ 20 ............. (1)

Where y is the distance in miles from the town and x represents the time of fly in hours.

So, at the start of the journey i.e. at x = 0, y = 20 miles {From equation (1)} from the town.

Again, Tasha's balloon is traveling at a rate of 8 miles per hour.

Now, Henry's balloon begins 30 miles from the town and is 48 miles from the town after 2 hours.

So, Henry's balloon traveling with the speed of  miles per hour.

Therefore, Henry's balloon was farther from the town at the beginning i.e. 30 miles from the town. And Henry's balloon traveled more quickly i.e at the rate of 9 miles per hour. (Answer)

3xy'+y=12x find general solution
Eduardwww [97]
The equation is linear, as you can write

3xy'+y=12x\implies y'+\dfrac1{3x}y=4

An integrating factor would be

\mu(x)=\exp\left(\displaystyle\int\frac{\mathrm dx}{3x}\right)=x^{1/3}

Multiplying both sides of the ODE by this yields

x^{1/3}y'+\dfrac1{3x^{2/3}}y=4x^{1/3}

where the LHS is a derivative:

\dfrac{\mathrm d}{\mathrm dx}\left[x^{1/3}y\right]=4x^{1/3}

Integrating both sides, we get

x^{1/3}y=4\displaystyle\int x^{1/3}\,\mathrm dx
x^{1/3}y=3x^{4/3}+C
y=3x^{3/3}+Cx^{-1/3}=3x+\dfrac C{x^{1/3}}

a motorcycle cost $12,000 when it was purchased. the value of a motorcycle decreases by 6% each year. find the rate of decay eac
kiruha [24]
There's 12 months in a year so if the value decreases by 6% each year that would be 6 ÷ 12 which is 0.5%. Therefore the decay each month is -0.5%.
