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

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

The x - intercept of 5x - 3y = 15 is (3, 0)

The y -intercept of 5x - 3y = 15 is (0, -5)

<h3>Solution:</h3>

Given equation is 5x - 3y = 15

To find: x - intercept and y -intercept

The x intercept is the point where the line crosses the x axis. At this point y = 0

The y intercept is the point where the line crosses the y axis. At this point x = 0.

Finding x - intercept:

To find the x intercept using the equation of the line, plug in 0 for the y variable and solve for x

So put y = 0 in given equation

5x - 3(0) = 15

5x = 15

x = 3

So the x - intercept is (3, 0)

Finding y - intercept:

To find the y intercept using the equation of the line, plug in 0 for the x variable and solve for y

So put x = 0 in given equation

5(0) - 3y = 15

-3y = 15

y = -5

So the y - intercept is (0, -5)

Lou's employer covers 70% of the cost of a $3800-per-year health insurance plan and 90% of the cost of a $1200per-year disabilit

gizmo_the_mogwai [7]

To answer this question correctly, first we must find out how much lou pays for health and disability insurance for a year total, then divide that number by 12, for each month of the year to find out how much he pays monthly. The calculation and answer would be the following: ((Health insurance cost * 30%) + (Disability cost * 10%)) / 12 = (1140+120)/12 = $105 monthly
