Use Euler’s method to estimate the value of y(20). Use a step size of ∆x = 5. Please fill out the remainder of the chart complet

Answer:

y(20)=14,322

Step-by-step explanation:

We need to solve the equation:

$dy/dx=0.4xy$

with initial point

$y(0) = 2$

with incerments

$\Delta x=h=5$

By Euler's method, we have:

$y(x+h)=y(x)+h*f'(x,y)$

We start with the initial point

$y(5)=y(0)+5*f'(0,2)=2+5*(0.4*0*2)=2$

And we continue until we reach the value for y(20)

$y(10)=y(5)+5*f'(5,2)=2+5*(0.4*5*2)=2+20=22\\\\\\y(15)=y(10)+5*f'(10,22)=22+5*(0.4*10*22)=22+440=462\\\\\\y(20)=y(15)+5*f'(15,462)=462+5*(0.4*15*462)=462+13,860\\\\y(20)=14,322$

What are the possible values of x in 8x2 + 4x = -1?

Rudiy27

Answer: x only can have complex values, not real values.

x = -1/4 - 1/4i and x = -1/4 + 1/4 i

Explanation:

Finding the possible values of x in the expression given is solving the quadratic equation.

8x² + 4x = - 1

Rearrange the terms:

8 (x² + x/2) = - 1 ← common factor 8 in the left side

x² + x/2 = - 1/8 ← division property

x² + x/2 + 1/16 = - 1/8 + 1/16 ← addition property

(x + 1/4)² = -1/8 + 1/16 ← -factor the perfect square trinomial in the left side

(x + 1/4)² = - 1/16 ← add the fractions in the right side

x + 1/4 = (+/-) √ (-1/16) ← square roots on both sides

x + 1/4 = (+/-) (1/4)i ← complex solution

x = - 1/4 +/- 1/4i

x = - 1/4 - 1/4i and x = - 1/4 + 1/4 i ← answer
