Find the general solution for differential equation (D4 - 5D3 + 5D2 + 5D - 6)y = 0

slava [35]

Given differential equation, (D4 - 5D3 + 5D2 + 5D - 6)y = 0

=> For general solution of equation,

Solve D4 - 5D3 + 5D2 + 5D - 6 = 0

=> D4 - 5D3 + 6D2 - D2 + 5D - 6 = 0

=> D2 (D2 - 5D + 6) - (D2 - 5D + 6) = 0

=> (D2 - 5D + 6)(D2 - 1) = 0 ................................(1)

Now

D2 - 1 = (D - 1)(D + 1) and

Factors of D2 - 5D + 6

D2 - 5D + 6 = D2 - 2D - 3D + 6

= D(D - 2) - 3(D - 2)

= (D - 3)(D - 2)

Therefore, equation (1) implies

(D2 - 5D + 6)(D2 - 1) = (D - 3)(D - 2)(D - 1)(D + 1) = 0

=> D = 3, 2, 1, -1 or D = -1, 1,, 2, 3

=> General solution of differential equation is,

=> y = C1 e-x + C2 ex + C3 e2x + C4 e3x .

Hope it helps

7. A clothing salesman wants to earn $6,000 in May. He receives a base salary of $4,000 per month as well as 10%

olya-2409 [2.1K]

Answer:

No of clothes to be sold to gain $6000=20,000

Given:

Base salary = $4000

Rate of Commission = 10%

Amount salesman wants to earn in May = $6000

To find:

How much clothing units needed to be sold in order gain $6000 in may

Step by Step Explanation:

Solution;

According to the formula;

$\text { Amount earned through commission }=\text { Total amount earned - Base salary }$

=6000 - 4000 = 2000

Also we know,

$\text { Amount earned through commission }=\text { Rate of Commission } \times \text { clothing to be sold }$

Let the commission amount be x

$10 \% \times x=2000$

$10 / 100 \times x=2000$

$0.1 \times x=2000$

$x=20,000 \div 0.1$

x=20,000

Result:

Hence, the clothing to be sold in order to earn $6000 is 20,000 units.

At a rate of 36 miles per hour, it takes Henry 15 minutes to drive from the library to his house. Show how to find the distance

EastWind [94]

This is applying the formula
$distance=rate*time$

We have a slight problem, though, because we are measuring rate in miles per hour, and we are measuring time in minutes. To make this problem solvable, we need to convert to either miles per minute or convert the time to hours. I'm going to convert the 15 minutes into hours:
$15min*\frac{1 hour}{60 min}=\frac{1}{4}hour$

Now that all of the units match, we have:
$distance=36\frac{mi}{hr}*\frac{1}{4}hr$

You can finish from there I'm sure.
