Solve the differential equation y" + 3y' + 2y = P1 where, y" = d2y/dx2, y' = dy/dx, P1 = P1(x)) and the initial conditions are y(0) = 0, y'(0) = 0. The input function is given by P1() = { 0, < 0 1, 0 ≤ ≤ 1 0, > 1

Answers

Answer 1

Answer:

[tex]y(x) = 0[/tex]

Step-by-step explanation:

Let P(1) = 0, the differential equation becomes:

y" + 3y' + 2y = 0

Also let y' = my and y'' = m²y

Substitute

m²y+3my+2y = 0

(m²+3m+2)y = 0

The auxiliary equation is expressed as:

m²+3m+2 = 0

Factorize

m²+2m+m+2 = 0

m(m+2)+1(m+2) = 0

(m+1)(m+2) = 0

m+1 = 0 and m+2 = 0

m₁ = -1 and m₂ = -2

Since the value of m is real and distinct, the solution to the differential equation will be expressed as:

[tex]y = C_1e^{m_1x}+C_2e^{m_2x}\\[/tex]

[tex]y(x) = C_1e^{-x}+C_2e^{-2x}\\[/tex]

Given the initial condition y(0) = 0

[tex]y(0) = C_1e^{-0}+C_2e^{-2(0)}\\0 = C_1+C_2\\C_1+C_2 = 0 ................. 1[/tex]

If y'(0) = 0

[tex]y'(x) = -C_1e^{-x}-2C_2e^{-2x}\\y'(0) = -C_1e^{-0}-2C_2e^{-2(0)}\\0 = -C_1-2C_2\\C_1-2C_2 = 0...................... 2[/tex]

Solve eqn 1 and 2 simultaneously

From 1:

C₁ = -C₂ .......... 3

Substitute equation 3 into 2:

-C₂-2C₂ = 0

-3C₂ = 0

C₂ = 0

Substitute the constant into the differential equation.

[tex]y(x) = C_1e^{-x}+C_2e^{-2x}\\\\y(x) = 0[/tex]

3. In the month of August, a car dealership sold a total of 72
cars and trucks. The dealership reported that for every 4
passenger cars sold, there were 2 trucks sold. How many of
each type of vehicle were sold in the month of August?

Answers

Answer:

The dealership sold in August 24 trucks and 48 cars

Step-by-step explanation:

Equations

A dealership reported they sold a total of 72 vehicles.

It also determined that for every 4 cars sold, they sold 2 trucks. It means that they sold twice as many cars as trucks.

Let x be the number of trucks sold.

It follows that 2x is the number of cars sold.

The sum of both numbers must equal 72:

x + 2x = 72

Simplifying:

3x = 72

Solving:

x = 72 / 3 = 24

The number of cars were

2x= 48

Answers

Answer:

Step-by-step explanation:

A symbol for a value we don't know yet. It is usually a letter like x or y.

Example: in x + 2 = 6, x is the variable.

Why "variable" when it may have just one value? In the case of x + 2 = 6 we can solve it to find that x = 4. But in something like y = x + 2 (a linear equation) x can have many values. In general it is much easier to always call it a variable even though in some cases it is a single value.

The ratio of money in Terry's bank account to Faye's bank account was 3:5.
Terry then put £220 in his account and Faye withdrew £300 from her account.
They now had the same amount in their accounts.
How much did they initially have altogether?

Answers

Answer:

£780 and £1300

Step-by-step explanation:

The ratio in their accounts is 3 : 5 = 3x : 5x ( x is a multiplier )

Terry put £220 into his account, then 3x + 220

Faye withdrew £300 from her account then 5x - 300

They now have the same amounts in their accounts, thus

5x - 300 = 3x + 220 ( subtract 3x from both sides )

2x - 300 = 220 ( add 300 to both sides )

2x = 520 ( divide both sides by 2 )

x = 260

Thus initial amount in their accounts

3 × £260 = £780 ← Terry's account

5 × £260 = £1300 ← Faye's account

f(x) = x + 2

f(-4)=
f(0) =
f(4)=

Answers

Answer:

-2, 2, 6

Step-by-step explanation:

f(-4)= -4+2=-2

f(0)=0+2=2

f(4)=4+2=6

Substitute x for the number in parentheses

The values of f(-4), f(0), and f(4) are -2, 2, and 6 after plugging the value of x: -4, 0, and 4.

What is a function?

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

It is given that:

The function f(x) = x + 2

To find the value of f(-4):

Plug x = -4 in the function:

f(-4) = -4 + 2 = -2

To find the value of f(0):

Plug x = 0 in the function:

f(0) = 0 + 2 = 2

To find the value of f(4):

Plug x = 4 in the function:

f(4) = 4 + 2 = 6

Thus, the values of f(-4), f(0), and f(4) are -2, 2, and 6 after plugging the value of x: -4, 0, and 4.

b. What percent is 17 out of 40

please help me!

Answers

Answer:

a. 3.6

b. 42.5%

Step-by-step explanation:

a. 180/100 = 1.8

1.8 times 2 (since it's 2%) gives us 3.6

B. 17/40 is 42.5

The value of 2% of 180 is 3.6.

The percent of 17 out of 40 is 42.50%.

Percentage can be described as a fraction out of an amount expressed as a number out of hundred. Percentages are represented with %.

In order to determine the value of 2% of 180, multiply 2/100 by 180.

2/100 x 180 = 3.6

In order to determine the percent of 17 out of 40, divide 17 by 40 and multiply by 100

(17/40) x 100 = 42.50%
