How long does it take a car to travel 200 mi at a constant speed of 25 mi/h?

First you have to do $200/25=8$ .
Since the car is moving at a constant rate, the answer would be 8h.

Bri and Annamarie are picking strawberries at two different strawberry farms that charge a flat fee plus a cost per basket picke

denpristay [2]

The correct answer is a & d.
If you find the equation for Annamarie, you get y = 2.75x+ 11.

Using the slope formula to find what Annamarie pays per basket.
(38.5 - 11)/(10 - 0) = 2.75
Annamarie's flat fee is $11 and Bri's flat fee is $5.50

I need help for the solution

Sonja [21]

Answer:

$\boxed{ \ dY_t=(2\theta+2\psi Y_t+\phi^2)dt+2\phi \sqrt{Y_t}dW_t\ }$

Step-by-step explanation:

it is a long time I have not applied Ito's lemma

I would say the following

for $f(x)=x^2$

f'(x)=2x

f''(x)=2

so using Ito's lemma we can write that

$dY_t=2V_tdV_t+\phi^2dt$

$dY_t=2(\theta+\psi V_t^2)dt+2\phi V_tdW_t+\phi^2dt$

$dY_t=(2\theta+2\psi V_t^2+\phi^2)dt+2\phi V_tdW_t$

so it comes

$dY_t=(2\theta+2\psi Y_t+\phi^2)dt+2\phi \sqrt{Y_t}dW_t$
