Find the general solution of the given higher-order differential equation. y(4) y''' y'' = 0
The homogeneous linear ODE
[tex]y^{(4)} + y''' + y'' = 0[/tex]
has characteristic equation
[tex]r^4 + r^3 + r^2 = r^2 (r^2 + r + 1) = 0[/tex]
with a double root at [tex]r=0[/tex] and two complex roots
[tex]r^2 + r + 1 = 0 \implies r = -\dfrac{1 \pm i\,\sqrt3}2[/tex]
Hence the characteristic solution is
[tex]y = C_1 e^{0x} + C_2x e^{0x} + C_3 e^{((-1/2)-i(\sqrt3/2))x} + C_4 e^{((-1/2)+i(\sqrt3/2))x}[/tex]
[tex]y = C_1 + C_2x \\\\ ~~~~~~~~~~ + C_3 e^{-x/2} \left(\cos\left(\dfrac{\sqrt3}2x\right) - i\, \sin\left(\dfrac{\sqrt3}2x\right)\right) \\\\ ~~~~~~~~~~ + C_4 e^{-x/2} \left(\cos\left(\dfrac{\sqrt3}2x\right) + i\,\sin\left(\dfrac{\sqrt3}2x\right)\right)[/tex]
[tex]y = C_1 + C_2x + C_3 e^{-x/2} \cos\left(\dfrac{\sqrt3}2x\right) + C_4 e^{-x/2} \sin\left(\dfrac{\sqrt3}2x\right)[/tex]

Determine the smallest integer that makes -3x + 7 -5x < 15 true.
Step-by-step explanation:
-3x+7-5x<15
-5x-3x+7<15
-8x+7<15
-8x<15-7
-8x<8
The smallest integer is -3x.
twice the larger of two consecutive integers is equal to fifteen less than three times the smaller
The larger of the two integers is 18 and the smaller integer is 17.
Integers are collection of whole numbers and negative numbers. Integers are not fractional numbers or decimal. Some examples of integers are -5,-25,0,13,9 .
Let us consider the smaller integer be x.
As the integers are consecutive, the larger integer is (x+1).
Now according to the given condition:
Twice the large integer=2(x+1)
15 less than the 3 times the smaller integer=3x-15
Now the value of these two expressions is equal.
Therefore: [tex]2(x+1)=3x+-15[/tex]
Solving the above equation to find the value of x:
[tex]or,2(x+1)=3x-15\\or,2x+2=3x-15\\or,2x-3x=-15-2\\or,-x=-17\\or,x=17[/tex]
Therefore the smaller integer is 17.
Larger integer(x+1) : 17+1=18
Therefore the integers are 17 and 18.

Answer:
47 / 3 ( Or 1 if you typed it wrong)
Step-by-step explanation:
When simplifying an equation like this, we always want to do our multiplication and division before addition and subtraction.
So for the first step, let's simplify the expression down to only addition and subtraction...
12 - 2 / 6 + 4 =
12 - (2 / 6) + 4 =
12 - 1/3 + 4
Now we can combine everything together from left to right...
(12 - 1/3) + 4 =
35/3 + 4 =
47 / 3
However...
If the original equation was:
[tex]\frac{12-2}{6+4}[/tex]
Then you would just simplify the top and bottom separately before dividing the two numbers, treating the fraction as parentheses.
So...
(12 - 2) = 10
(6 + 4) = 10
And since 10 / 10 = 1
The answer to the fraction simplification is 1.
The solution of the expression would be 47/3.
Given that,
The expression is,
[tex]12 - \dfrac{2}{6} + 4[/tex]
Now simplify the expression by applying the BODMAS rule,
[tex]12 - \dfrac{2}{6} + 4[/tex]
[tex]12 - \dfrac{1}{3} + 4[/tex]
[tex]16 - \dfrac{1}{3}[/tex]
[tex]\dfrac{(48 - 1)}{3}[/tex]
[tex]\dfrac{47}{3}[/tex]
Therefore, the solution of the expression is 47/3.

When applying PEMDAS, always work from left to right. True or False?
Answer:
False
Step-by-step explanation:
Sometimes, multiplication can occur after addition. For example, in 3+4*7, you don't add 3 and 4 first. You multiply 4 and 7 first since that's following the PEMDAS rule. After multiplying 4 and 7, then you add 3 to get a total of 31. ==> 3+4*7=3+28=31.
From nine cards numbered 1 through 9, two cards are drawn. consider the selection and classification of the cards as odd or even as an experiment. how many sample points are there for this experiment?
Probability= 5/9
Even cards = 2,4,6,8
Odd cards = 1,3,5,7,9
The number of ways of choosing one odd and one even number is 5C1 * 4C1
( 5!/ 1!* 4!) * (4!/1! * 3!)
5* 4= 20
Total number of ways of choosing 2 cards out of 9 = 9C2
9!/ 2! * (9-2)!
= 9!/ 2! * 7!
= 9*8/2
= 9 *4= 36
Thus, Probability is = 20/ 36

Find the area of the region that lies inside both curves. r = 9 sin(), r = 9 cos()
The area of the region inside both curves r = 9 sin(θ) and r = 9 cos(θ) is 11.56 square units.
What is integration?It is defined as the mathematical calculation by which we can sum up all the smaller parts into a unit.
The curves are:
r = 9 sin(θ) and
r = 9 cos(θ)
On graphing the above curves:
From the graph:
A = (1/2)∫(9sin(θ))2dθ + (1/2)∫(9cos(θ)2dθ
The region is symmetrical about π/4,:
A = 81∫sin2(θ)dθ from 0 to π/4
After solving:
= 11.56 square unit
Thus, the area of the region inside both curves r = 9 sin(θ) and r = 9 cos(θ) is 11.56 square units.

Jamal loves his dog, Rupert. On sunny days, Jamal keeps Rupert on a 12-foot leash
in the backyard. He secures the leash to a stake in the ground.
> Answer each question and use 3.14 for T.
1 Determine the diameter, circumference, and area of Rupert's play area.
Diameter = 24 foot, circumference = 75.36 foot, Area = 452.16 square foot
As the leash is 12 feet, and dog Rupert will form a circle in the backyard.
As the leash is of 12 feet, so it is the radius(r) of the circle.
Diameter = 2r
= 2×12
= 24 foot
Circumference = 2πr
=2×3.14×12
= 75.36 foot
Area of the circle = π[tex]r^{2}[/tex]
= 3.14×[tex]12^{2}[/tex]

A rectangle is 15 cm wide. Find the area and the perimeter of the rectangle if its width is 3/5 of its length
The area and perimeter of the rectangle are 80 cm and 375 cm² respectively.
How to find area and perimeter of a rectangle?The rectangle is 15 cm wide.
The width is 3 / 5 of its length
Therefore, the area and the perimeter of the rectangle can be found as follows:
area of a rectangle = lw
where
l = lengthw = widthTherefore,
w = 15 cm
15 = 3 / 5 × l
cross multiply
75 = 3l
l =75 / 3
l = 25 cm
Therefore,
area of the rectangle = 25 × 15 = 375 cm²
Perimeter of the rectangle = 2l + 2w
Perimeter of the rectangle = 2(l + w)
Perimeter of the rectangle = 2(25 + 15)
Perimeter of the rectangle = 2(40)
Perimeter of the rectangle = 80 cm
Therefore, the area and perimeter of the rectangle are 80 cm and 375 cm² respectively.

Which graph represents 7x - 2y < 5?
f(x) = -x² - 8x - 16; Find ƒ(-3)
f(-3) = -1
Step-by-step explanation:We can find an unknown y-value by plugging an x-value into a given function.
Function Notation
Before we answer this question, we need to understand the notation of the equation. In function notation, the equation is given in terms of f(x).
"f(x)" represents the y-value of a function at the point "x".For example, f(-3) represents the value of y when x = -3.
Finding f(3)
As stated above, to find f(-3) we need to plug -3 in for x. *Remember to use PEMDAS when solving.* This creates the new equation:
f(-3) = -(-3)² - 8(-3) - 16Then, distribute the exponent.
f(-3) = -9 - 8(-3) - 16Next, multiply.
f(-3) = -9 - (-24) - 16Distribute the negative.
f(-3) = -9 + 24 - 16Finally, add the remaining terms.
f(-3) = -1This means that when x = -3, y or f(-3) = -1.
