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
crimeas [40]

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

A wooden jewelry box has the shape of a prism with a regular hexagonal base of 85.3 in2. The sides of the hexagonal base are all
Anna35 [415]

Answer:

792.9 in²

Step-by-step Explanation:

Given:

Area of the base of the regular hexagonal prism box (B) = 85.3 in²

Each side length of hexagonal base (s) = 5.73 in

Height of prism box (h) = 18.10 in

Required:

Surface area of the wood used in making the hexagonal prism box

SOLUTION:

Surface area for any given regular prism can be calculated using the following formula: (Perimeter of Base × height of prism) + 2(Base Area)

Perimeter of the hexagonal base of the prism box = 6(5.73) (Note: hexagon has 6 sides.)

Perimeter of base = 34.38 in

Height = 18.10 in

Base area is already given as 85.3 in²

Surface area of the hexagonal prism box = (34.38*18.10) + 2(85.3)

= 622.278 + 170.6 = 792.878 in^2

<em>Surface area of the wood used in making the jewelry box ≈ 792.9 in²</em>
