A stadiums parking lot can accommodate 5,000 vehicles. If 35% of the 75,000 fans drive to tonight’s game with two fans per car h

geniusboy [140]

Answer:

35 percent of the 75,000 fans is: 0.35*75,000 = 26,250

since there are 2 fans per car we find the number of cars by dividing 26,250 by 2:

26,250 : 2 = 13,125 cars

5,000 will park at the stadium's parking lots, while the rest 13,125 - 5,000 = 8,125 cars will par at satellite lots.

35% of 75000 = 26250

2 fans in a car

So, = 26250/2

= 13125

Total handling space = 5000

13125 - 5000 = 8125

Find the solution of the differential equation that satisfies the given initial condition. y' tan x = 3a + y, y(π/3) = 3a, 0 &lt

Paladinen [302]

Answer:

$y(x)=4a\sqrt{3}* sin(x)-3a$

Step-by-step explanation:

We have a separable equation, first let's rewrite the equation as:

$\frac{dy(x)}{dx} =\frac{3a+y}{tan(x)}$

But:

$\frac{1}{tan(x)} =cot(x)$

So:

$\frac{dy(x)}{dx} =cot(x)*(3a+y)$

Multiplying both sides by dx and dividing both sides by 3a+y:

$\frac{dy}{3a+y} =cot(x)dx$

Integrating both sides:

$\int\ \frac{dy}{3a+y} =\int\cot(x) \, dx$

Evaluating the integrals:

$log(3a+y)=log(sin(x))+C_1$

Where C1 is an arbitrary constant.

Solving for y:

$y(x)=-3a+e^{C_1} sin(x)$

$e^{C_1} =constant$

So:

$y(x)=C_1*sin(x)-3a$

Finally, let's evaluate the initial condition in order to find C1:

$y(\frac{\pi}{3} )=3a=C_1*sin(\frac{\pi}{3})-3a\\ 3a=C_1*\frac{\sqrt{3} }{2} -3a$

Solving for C1:

$C_1=4a\sqrt{3}$

Therefore:

$y(x)=4a\sqrt{3}* sin(x)-3a$
