Find the general solution of the given second-order differential equation. 3y'' 2y' y = 0
Answers
The general solution of the given differential equation are: [tex]e^{\frac{-x}{3}}[/tex] [A cos(x√ 2/3) + B sin(x√ 2/3) i ]
What are differential equations?A differential equation is an equation that connects the derivatives of one or more unknown functions. Applications often involve functions that reflect physical quantities, derivatives that depict the rates at which those values change, and a differential equation that establishes a connection between the two.Now,
Given: 3y'' + 2y' + y = 0
To find: General solution of the given differential equation.
Finding:
=> [tex]3\frac{d^{2}y}{dx^{2}} + 2 \frac{dy}{dx} + y = 0[/tex]
The characteristic equation of this equation is:
=> 3m² + 2m + 1 = 0
=> m = [tex]\frac{(-2)± \sqrt{4 - 4(3)(1)}}{2(3)}[/tex]
=> m = [tex]\frac{(-2)±\sqrt{4-12}}{6}[/tex]
=> m = [tex]\frac{(-2)±2\sqrt{2}i}{6}[/tex]
=> m = [tex]\frac{(-1)±\sqrt{2}i}{3}[/tex] = [tex]\frac{-1}{3}[/tex] ± [tex]\frac{\sqrt{2}}{3}[/tex]
Thus, For a = -1/3 and b = (√2)/3,

What is the average accerlation during the time interval 0 seconds to 10 seconds?
Answers
The average acceleration during the time interval 0 seconds to 10 seconds is [tex]\frac{V_{1}-V_{2} }{10}[/tex] unit per second per second.
As per the question statement, we are supposed to find out the average acceleration during the time interval 0 seconds to 10 seconds. But before solving this question we should be aware about what actually average acceleration is.
Average acceleration : [tex]\frac{change in velocity}{total time interval}[/tex]
Here in the question, we are not given information about velocity of the object hence we assume the initial and final velocities of the object to be [tex]V_{1}[/tex] and [tex]V_{2}[/tex] respectively, hence
Change in velocity = [tex]V_{1}-V_{2}[/tex]
Total time interval = [tex](10 - 0)sec=10sec[/tex]
Therefore by definition of average acceleration we get
[tex]A_{avg}[/tex][tex]= \frac{V_{1}-V_{2} }{10}[/tex] unit per sec per second
Average acceleration: The rate at which the velocity changes is referred to as average acceleration. To determine the average acceleration of something, we divide the change in velocity by the amount of time that has passed.To learn more about acceleration and kinetics, click on the link given below:

One number is 5 less than twice another
number. If the sum of the numbers is 7, find
both numbers
Answers
Answer:
4 and 3
Step-by-step explanation:
You can create an equation with this. If your first number is y and your second is x, then we know that y is 5 less than 2x. This leads to your equation - y = 2x - 5.
With your equation, you can then figure out your numbers; we know there's a limited number of possibilities - anything 7 or less added to a number can equal 7 so:
7+0=7
6+1=7
5+2=7
4+3=7
3+4=7
2+5=7
1+6=7
0+7=7
From there, plug in one number for x and see if y matches the expected number. For example:
2(7)-5=9, so we know the 7,0 combination cannot be correct. As we go through the list, we find that 4,3 works:
2(4)-5=3

Through how many radians will the hour hand on a clock rotate in (a) 23 hr? In (b) 6 hr? (a) In 23 hr, the hour hand on the clock will rotate radians
Answers
The radians will the hour hand on a clock rotation for 23hr and 6hr is 23/6π and π.
We have to find the radians will the hour hand on a clock rotation for 23hr and 6hr.
One revolution is done by fully around the circle with the radius. After one full rotation, the radius subtends an angle of 2π radians at the circle's center. To illustrate the conversion of 1 radian to degrees, we will use the knowledge that 2π radians = 360 degrees.
2π radians = 360°
Divide the above equation by 2,
⇒ π radians = 180°
Divide the above equation by π,
⇒ 1 radian = 180°/π
⇒ 1 radian = 57.296°
Only 12 hours are represented by one full rotation of the hour hand. A whole rotation equals 360°, or two radians.
11 hours rotation equals to 330°, or 11π/6 radians.
23 hours=12+11
=360°+330° (or) 2π+11π/6
=690° (or) 23π/6
Now, 6 hours=12/2
=360°/2 (or) 2π/2
=180° (or) π.
Therefore, the radians will the hour hand on a clock rotation for 23hr and 6hr is 23/6π and π.

Since K is the midpoint both equations are equal to eachother so the first equation is
8x+11=14x-1
-6x+11=-1
-6x=-12
x=2
Now since we have x we can solve so youre going to put x into one of the equations. It doesnt matter which once cause they are both equal. So we can do 8x+11
8(2)+11
16+11
27

Can theses lengths form a right triangle (5,6,V30)
Answers
No these lengths does not form a right triangle
There is a property of triangles which says that some of two sides of the triangle should be more than the third side of the triangle
So first case 6,30,5
30+6 =36 which is more than 5
second case 5,30,6
5+30 =35 which is more than 6
third case 5,6,30
5+6 =11 which is not more than 30
as in third case the property is breached because sum of two sides of triangle is not more than third side so the figure cannot be a triangle .

How much more can paula shovel in 1 minute than melinda? 3 square feet per minute 6 square feet per minute 9 square feet per minute 15 square feet per minute
Answers
Paula shovels 3 square feet more than Melinda in 1 minute.
We are given two equations relating the distance covered by each while they shovel. Assuming the x to be representative of Melinda's speed and y to be representative of Paula's speed. Making at least one coefficient same for both the equation.
Equation 1 : 30x + 30y = 450
Equation 2 : 20x + 25y = 345
Dividing equation 1 and equation 2 by 5.
Equation 3 : 6x + 6y = 90
Equation 4 : 4x + 5y = 69
Multiplying equation 3 with 4 and equation 4 with 6.
Equation 5 : 24x + 24y = 360
Equation 6 : 24x + 30y = 414
Subtracting Equation 5 from Equation 6.
24x + 30y = 414
- 24x + 24y = 360
6y = 54
y = 9
Keep the value of y in equation 3
6x + 6×9 = 90
6x + 54 = 90
6x = 90 - 54
6x = 36
x = 6
So, Melinda's speed is 6 square feet per minute and Paula's speed is 9 square feet per minute.
Difference between speed = 9 - 6
Difference = 3 square feet per minute
Hence, Paula's speed is 3 square feet per minute more than Melinda.
