The differential equation y′′=0 has one of the following two parameter families as its general solution: yyyy=C1ex+C2e−x=C1cos(x

svet-max [94.6K]

Answer:

y_c = 2 + 10*x

Step-by-step explanation:

Given:

y'' = 0

Find:

- The solution to ODE such that y(0) = 2, y'(0) = 10

Solution:

- Assuming a solution y = Ce^(mt)

So, y' = C*me^(mt)

y'' = C*m^2e^(mt)

- Back substitute into given ODE, we get:

y'' = C*m^2e^(mt) = 0

e^(mt) can not be equal to zero

- Hence, m^2 = 0

m = 0 , 0 - (repeated roots)

- The complimentary function for repeated roots is:

y_c = (C1 + C2*x)*e^(m*t)

y_c = C1 + C2*x

- Evaluate @ y(0) = 2

2 = C1 + C2*0

C1 = 2

-Evaluate @ y'(0) = 10

y'(t) = C2 = 10

Hence, y_c = 2 + 10*x

What is the surface area of the pyramid?

-Dominant- [34]

Answer:

166 square units

Step-by-step explanation:

Let’s find the area of the shapes that in the net.

First, we can see two of the triangles have a base of 2 and a height of 13. The formula for surface area of a triangle is bh÷2. (13x2)÷2=13. Since there are two triangles, we multiply 13 by 2 and get 26.

Second, we can see two of the triangles have a base of 10 and a height of 12. (10x12)÷2=60. Since there are two triangles, we multiply 60 by 2 and get 120.

Third, we can see a rectangle has a base of 10 and a height of 2. The formula for surface area of a rectangle is bh. 10x2=20.

Last, we add up all the areas:

20+120+26=166.
