Answer:
[tex]1 \rightarrow E, 2\rightarrow B, 3\rightarrow C, 4\rightarrow D, 5\rightarrow A[/tex]
Step-by-step explanation:
1. [tex]\frac{d^2y}{dx^2}+25y=0[/tex]
The characteristic equation for the given differential equation is:
[tex]r^{2} +25=0[/tex]
[tex]\Rightarrow r^2=-25[/tex]
[tex]\Rightarrow r=\pm 5i[/tex]
Since the roots are complex
Now, the general solution is:
[tex]y=A\cos 5x+B\sin 5x[/tex]
2. [tex]\frac{dy}{dx}=\frac {2xy}{x^2}-5y^2[/tex]
[tex]\Rightarrow \frac{dy}{dx}-\frac 2xy=-5y^2[/tex]
Divide both sides by [tex]y^{-1}[/tex]
Let, [tex]v=y^{-1} \Rightarrow \frac{dv}{dx}=-y^{-2}\frac{dy}{dx}[/tex]
[tex]\Rightarrow -\frac{dv}{dx}-\frac 2xv=-5[/tex]
[tex]\Rightarrow \frac{dv}{dx}+\frac 2xv=5[/tex]
Here, [tex]p(x)=\frac 2x\; \text{and}\;\; q(x)=5[/tex]
I.F. [tex]=e^{\int \frac 2xdx}=x^2[/tex]
Now, the general solution is:
[tex]vx^2=\int x^2 5dx=\frac {5x^3}3+c[/tex]
[tex]\Rightarrow \frac {x^2}y-\frac {5x^3}3=c[/tex]
[tex]\Rightarrow 3x^2-5x^3y=Cy[/tex]
3. [tex]\frac{d^2y}{dx^2}+16\frac{dy}{dx}+64y=0[/tex]
The characteristic equation is:
[tex]r^2+16r+64=0[/tex]
[tex]\Rightarrow r^2+8r+8r+64=0[/tex]
[tex]\Rightarrow r(r+8)+8(r+8)=0[/tex]
[tex]\Rightarrow (r+8)(r+8)=0[/tex]
[tex]\Rightarrow r=-8,-8[/tex]
Since the roots are real and repeated.
Now, the general solution is:
[tex]y=Ae^{-8x}+Bxe^{-8x}[/tex]
4. [tex]\frac {dy}{dx}=10xy[/tex]
[tex]\Rightarrow \frac {dy}{y}=10xdx[/tex]
Integrating both sides
[tex]\int\frac {dy}y=\int 10xdx+\log c[/tex]
[tex]\Rightarrow \log y=5x^2+\log c[/tex]
[tex]\Rightarrow y=e^{5x^2}+c[/tex]
5. [tex]\frac {dy}{dx}+24x^2y=24x^2[/tex]
Here, [tex]p(x)=24x^2 \; \text{and}\;\; q(x)=24x^2[/tex]
I.F.[tex]= e^{\int 24x^2dx}=e^{8x^3}[/tex]
Now, the general solution is:
[tex]y.e^{8x^3}=\int 24x^2 e^{8x^3}dx=24\int x^2e^{8x^3}dx[/tex]
Let, [tex]8x^3=t \Rightarrow 24x^2dx=dt\Rightarrow x^2dx=\frac {dt}{24}[/tex]
[tex]\Rightarrow ye^{8x^3}=\int e^tdt[/tex]
[tex]\Rightarrow ye^{8x^3}=e^{8x^3}+c[/tex]
[tex]\Rightarrow y=1+ce^{-8x^3}[/tex]
NEED HELP AND HOW U GOT THE ANSWER PLEASE find the measure of the angle greater than BXC using the figure below
Answer:
m∠BXC = 30°
Step-by-step explanation:
The symbol ∠ means "angle", so "angle ∠BXC" is actually redundant. The "greater than" symbol is "<", which sometimes is used when the proper angle symbol is not available.
Here, the question is simply asking for the measure of angle BXC.
Ray BX crosses the outer, inner scales of the protractor at 40, 140. Ray CX crosses those scales at 70, 110. The measure of angle BXC in degrees is the difference between the numbers on the same scale:
70 -40 = 30 . . . using outer scale numbers
140 -110 = 30 . . . using inner scale numbers
The measure of angle BXC is 30°.

Step-by-step explanation:
Find c1 and c2 such that M2+c1M+c2I2=0, where I2 is the identity 2×2 matrix and 0 is the zero matrix of appropriate dimension.
The question is missing parts. Here is the complete question.
Let M = [tex]\left[\begin{array}{cc}6&5\\-1&-4\end{array}\right][/tex]. Find [tex]c_{1}[/tex] and [tex]c_{2}[/tex] such that [tex]M^{2}+c_{1}M+c_{2}I_{2}=0[/tex], where [tex]I_{2}[/tex] is the identity 2x2 matrix and 0 is the zero matrix of appropriate dimension.
Answer: [tex]c_{1} = \frac{-16}{10}[/tex]
[tex]c_{2}=\frac{-214}{10}[/tex]
Step-by-step explanation: Identity matrix is a sqaure matrix that has 1's along the main diagonal and 0 everywhere else. So, a 2x2 identity matrix is:
[tex]\left[\begin{array}{cc}1&0\\0&1\end{array}\right][/tex]
[tex]M^{2} = \left[\begin{array}{cc}6&5\\-1&-4\end{array}\right]\left[\begin{array}{cc}6&5\\-1&-4\end{array}\right][/tex]
[tex]M^{2}=\left[\begin{array}{cc}31&10\\-2&15\end{array}\right][/tex]
Solving equation:
[tex]\left[\begin{array}{cc}31&10\\-2&15\end{array}\right]+c_{1}\left[\begin{array}{cc}6&5\\-1&-4\end{array}\right] +c_{2}\left[\begin{array}{cc}1&0\\0&1\end{array}\right] =\left[\begin{array}{cc}0&0\\0&0\end{array}\right][/tex]
Multiplying a matrix and a scalar results in all the terms of the matrix multiplied by the scalar. You can only add matrices of the same dimensions.
So, the equation is:
[tex]\left[\begin{array}{cc}31&10\\-2&15\end{array}\right]+\left[\begin{array}{cc}6c_{1}&5c_{1}\\-1c_{1}&-4c_{1}\end{array}\right] +\left[\begin{array}{cc}c_{2}&0\\0&c_{2}\end{array}\right] =\left[\begin{array}{cc}0&0\\0&0\end{array}\right][/tex]
And the system of equations is:
[tex]6c_{1}+c_{2} = -31\\-4c_{1}+c_{2} = -15[/tex]
There are several methods to solve this system. One of them is to multiply the second equation to -1 and add both equations:
[tex]6c_{1}+c_{2} = -31\\(-1)*-4c_{1}+c_{2} = -15*(-1)[/tex]
[tex]6c_{1}+c_{2} = -31\\4c_{1}-c_{2} = 15[/tex]
[tex]10c_{1} = -16[/tex]
[tex]c_{1} = \frac{-16}{10}[/tex]
With [tex]c_{1}[/tex], substitute in one of the equations and find [tex]c_{2}[/tex]:
[tex]6c_{1}+c_{2}=-31[/tex]
[tex]c_{2}=-31-6(\frac{-16}{10} )[/tex]
[tex]c_{2}=-31+(\frac{96}{10} )[/tex]
[tex]c_{2}=\frac{-310+96}{10}[/tex]
[tex]c_{2}=\frac{-214}{10}[/tex]
For the equation, [tex]c_{1} = \frac{-16}{10}[/tex] and [tex]c_{2}=\frac{-214}{10}[/tex]

Answer:
y = -14x - 80
Step-by-step explanation:
jst did it and i got it right
The equation of the line passing through the points (−6,4) and (−5,−10) is y = -14x - 80.
What is a straight line?A straight line is a combination of endless points joined on both sides of the point.
The slope 'm' of any straight line is given by:
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
The line through the points (−6,4) and (−5,−10).
(y + 10) = (-10-4)/(-5+6)[x + 5]
y + 10 = -14(x + 5)
y + 10 = -14x - 70
y = -14x - 80
Thus, the equation of the line passing through the points (−6,4) and (−5,−10) is y = -14x - 80.

Determine perimeter of the kite
First, we need to determine lengths of sides WX, XY, YZ and ZW using distance formula;
[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]
For WX:
[tex](x_1, y_1)\ (x_2,y_2) = (-3, 3),\ (2, 3)[/tex]
[tex]WX = \sqrt{(-3 - 2)^2 + (3 - 3)^2}[/tex]
[tex]WX = \sqrt{(-5)^2 + (0)^2}[/tex]
[tex]WX = \sqrt{25}[/tex]
[tex]WX = 5[/tex]
For XY:
[tex](x_1, y_1)\ (x_2,y_2) = (2, 3)\ (4,-4)[/tex]
[tex]XY = \sqrt{(2 - 4)^2 + (3 - (-4))^2}[/tex]
[tex]XY = \sqrt{-2^2 + (3 +4)^2}[/tex]
[tex]XY = \sqrt{-2^2 + 7^2}[/tex]
[tex]XY = \sqrt{4 + 49}[/tex]
[tex]XY = \sqrt{53}[/tex]
For YZ:
[tex](x_1, y_1)\ (x_2,y_2) = (4,-4)\ (-3, -2)[/tex]
[tex]YZ = \sqrt{(4 - (-3))^2 + (-4 - (-2))^2}[/tex]
[tex]YZ = \sqrt{(4 +3)^2 + (-4 +2)^2}[/tex]
[tex]YZ = \sqrt{7^2 + (-2)^2}[/tex]
[tex]YZ = \sqrt{49 + 4}[/tex]
[tex]YZ = \sqrt{53}[/tex]
For ZW:
[tex](x_1, y_1)\ (x_2,y_2) = (-3, -2)\ (-3, 3)[/tex]
[tex]ZW = \sqrt{(-3 - (-3))^2 + (-2 - 3)^2}[/tex]
[tex]ZW = \sqrt{(-3 +3)^2 + (-2 - 3)^2}[/tex]
[tex]ZW = \sqrt{0^2 + (-5)^2}[/tex]
[tex]ZW = \sqrt{0 + 25}[/tex]
[tex]ZW = \sqrt{25}[/tex]
[tex]ZW = 5[/tex]
The Perimeter (P) is as follows:
[tex]P = WX + XY + YZ + ZW[/tex]
[tex]P = 5 + \sqrt{53} + \sqrt{53} + 5[/tex]
[tex]P = 5 + 5 + \sqrt{53} + \sqrt{53}[/tex]

Absolute value is the distance between that number and zero. To find the absolute value, you basically just take the negative sign away if there is one. So you need to find the absolute value of 4x+6. Since you can't simplify this equation, you just keep it the way it is. The absolute value of 4x+6 is 4x+6.
So now you have 4x + 6 - 1. Since 6 and 1 are both constant variables, you can directly subtract it. 6-1 equals 5. Now you have 4x-5.
Now you have 4x-5 = -1 = 3x. You should isolate the variables as well as "removing" an equal sign. To bring away the -1, you have to add 1. -1 + 1 equals 0, AKA nothing. But you also have to do it with all the other expressions too...
4x - 5 + 1 = 4x-6
3x+1 = 3x+1
Now the equation is 4x-6 = 3x+1
So now you have to get rid of the 6. To do that, add 6 to each side of the equation.
4x-6+6 = 4x
3x+1+6 = 3x+7
Now the equation is 4x = 3x+7
Did you notice that you have to add 1x to 3x to get 4x?
3x+1x = 4x (AKA the left side of the equation)
Also, you added the 7.
So that means 7 is the 1x.
So x equals 7.

Corbin is helping his grandfather plant the corn in the field. The field covers an area of 43,200 square feet. The length of the field is triple the width. What are the dimensions?
Answer:
the length is 360 feet and the width is 120 feet.
Step-by-step explanation:
Set up an equation with the area formula, A = lw
The width can be represented by x, and the length can be represented by 3x since it is 3 times the width
43,200 = (3x)(x)
43,200 = 3x²
Solve for x:
14,400 = x²
120 = x
So, the width is 120 feet.
The length is 3 times this, so multiply the width by 3 to find the length
120(3)
= 360
So, the length is 360 feet and the width is 120 feet.
-18-3s=15 solve for s. can someone plz help
Answer:
The correct answer is s = -11.
Step-by-step explanation:
To solve this problem, we must move all of the variable terms to one side of the equation and move all of the constant terms to the other side. Let's keep the variable terms on the left and move the constants to the right. Our first step will be to add 18 to both sides of the equation to cancel out the -18 on the left side:
-18 + 18 - 3s = 15 + 18
-3s = 33
Our next and final step will be to divide both sides by -3 to get the variable s completely isolated on the left side of the equation.
-3s/-3 = 33/-3
s = -11
Therefore, the correct answer is s = -11.

To find the fraction of the money by which Bello's share is greater than Okpala's and Olu's shares put together, we need to calculate the difference between Bello's share and the sum of Okpala's and Olu's shares, and then express it as a fraction of the total sum of money M.
Bello's share - (Okpala's share + Olu's share) = (M - Okpala's share - Olu's share) - (Okpala's share + Olu's share)
= M - Okpala's share - Olu's share - Okpala's share - Olu's share
= M - 2(Okpala's share) - 2(Olu's share)
= M - 2[(1/6)M] - 2[(1/4)M]
= M - (1/3)M - (1/2)M
= M - (2/6)M - (3/6)M
= M - (5/6)M
= (1/6)M
Now, let's express this difference as a fraction of the total sum of money M:
Fraction of Bello's share greater than Okpala's and Olu's shares
= [(1/6)M] / M
= (1/6)
Therefore, Bello's share is greater than Okpala's and Olu's shares combined by a fraction of 1/6 of the total sum of money.

Answer ASAP and I'll make you the brainliest Alberto multiplied a whole number by a fraction. The whole number is greater than 1. The fraction is greater than 0 and less than 1. Which BEST describes the product of the whole number and the fraction? A. equal to the fraction B. equal to the whole number C. less than the whole number D. greater than the whole number
Answer:
C. less than the whole number
Step-by-step explanation:
Think of the product as 1/2(0.5)×3 ; the answer would equal 1.5, half of 3. Any number less than 1, multiplied by a whole number, always comes out with a product less than the whole numbers. i.e. 1/3(0.3)×9 = 3
1/4(0.25)×8 = 2
1/5(0.20)×5 = 1
(Anyone correct me if I'm wrong.)
Answer: C) less than the whole number
Step-by-step explanation: I tried examples and they are less than the whole number. The first choice is also equal to the fraction but that’s not for most cases.
