Find the general solution of the differential equation or state that the differential equation is not separable. (Enter NOT SEPARABLE if the equation is not separable.) yy' = = 8x
This differential equation is separable.
To solve, we can first rewrite the equation as:
y dy = 8x dx
Next, we integrate both sides with respect to their respective variables:
∫y dy = ∫8x dx
(1/2)y^2 = 4x^2 + C
where C is the constant of integration.
Finally, we solve for y:
y = ±sqrt(8x^2 + 2C)
Therefore, the general solution of the differential equation is:
y = ±sqrt(8x^2 + 2C)
In calculus, the constant of integration is an arbitrary constant that appears when finding the indefinite integral (antiderivative) of a function. When taking the derivative of a function, any constant terms drop out, but when integrating a function, there is no way to know whether a constant term was present in the original function, so it is added as the constant of integration.
For example, suppose we want to find the indefinite integral of the function f(x) = x. We can do this by applying the power rule of integration, which states that the integral of x^n with respect to x is (x^(n+1))/(n+1) plus the constant of integration C:
∫x dx = (x^2)/2 + C
The constant of integration C is added to the antiderivative because when we differentiate (x^2)/2, the constant term 1/2 disappears, leaving us with just x.

The number of goldfish in a tank is 22, and the volume of the tank is 56 cubic feet. what is the density of the tank? 0.34 goldfish per cubic foot 0.39 goldfish per cubic foot 1.41 goldfish per cubic foot 2.55 goldfish per cubic foot
Option B is correct. 0.39 goldfish per cubic feet is the density of the tank given that there are 22 goldfishes and volume of the tank is 56 cubic feet. This can be obtained by using the formula of density.
Calculate the density of tank:Given that there are 22 goldfishes,
mass of tank = 22 goldfishes
volume of tank = 56 cubic feet
Density = mass/volume= 22/56
= 0.39 goldfish per cubic feet
Hence 0.39 goldfish per cubic feet is the density of the tank given that there are 22 goldfishes and volume of the tank is 56 cubic feet.

equivalent to the complex number i^14
Answer: The powers of i have a repetitive cyclic nature.
When we raise the imagenry unit i to increasing powers, we get a pattern which repeats itself.
Observe the following table of powers of i.
Power of i i1 i2 i3 i4 i5 i6 i7 i8 i9
Simplified i -1 -i 1 i -1 -i 1 i
As you see above, the pattern repeats itself and is four members long.
Therefore, ix+8 ix+4 will equalx.
When asked to determine the value of i to a power higher than 4, we can use this information in order to find our position in the cycle.
So, instead of using the actual power, we can take the remainder of the power divided by 4.

b=5
Write the equation in slope intercept form as:
y=mx+b
y=(0)x+5
y=5
Hence, the equation of the line is y=5.
Answer:
a = 3
Step-by-step explanation:
Since the line passes through the origin, we can find its equation using the two given points.
The slope of the line is:
m = (3 - 9) / (40 - a - 2a - 50) = -6 / (10 - 3a)
Using the point (2a+50, 9), we can find the y-intercept (b) of the line:
9 = m(2a+50) + b
b = 9 - m(2a+50)
b = 9 + (6/(3a-10))(2a+50)
So the equation of the line is:
y = (-6 / (3a-10))x + (9 + (6/(3a-10))(2a+50))
Since the line passes through the origin, the y-intercept (b) must be zero. Therefore:
0 = 9 + (6/(3a-10))(2a+50)
6(2a+50) = -9(3a-10)
12a + 300 = -27a + 90
39a = 210
a = 210/39
a = 3

Treatment 1116 Error 1068 Total 2184 A. 7.48
B. 7.84
C. 8.84
D. 8.48
Therefore, the answer is option B. 7.84.
How to find the Mean Square Treatment?To calculate the computed value of F, we need to use the formula:
F = Mean Square Treatment / Mean Square Error
From the ANOVA table, we can see that the Treatment and Error sum of squares are 1116 and 1068, respectively.
The degrees of freedom for Treatment is dfTreatment = 3-1= 2 and the degrees of freedom for Error is dfError = (3 x 6) - 3 = 15.
Using these values, we can compute the Mean Square Treatment as:
Mean Square Treatment = Sum of Squares Treatment / dfTreatment = 1116 / 2 = 558
And the Mean Square Error as:
Mean Square Error = Sum of Squares Error / dfError = 1068 / 15 = 71.2
Thus, the computed value of F is:
F = Mean Square Treatment / Mean Square Error = 558 / 71.2 = 7.84
Therefore, the answer is option B. 7.84.

The area over which the signal is transmitted are: a.\(\pi\) b. \(25\pi\) c. CB transmits 25 times more signal to walkie talkie.
What is ratio?When two quantities of the same units are compared, the ratio shows how much of one quantity is included in the other. Two categories can be used to categorize ratios. Part to whole ratio is one, while part to part ratio is the other.
The area of the circle is given by the formula:
\(A = \pi r^2\)
For the walkie-talkie the signal is received up until 1 mile. Substitute the value of r = 1.
\(A _1= \pi (1)^2\\\\A_1 =\pi\)
For the CB radio the signal is received up until 5 miles. Substitute the value of r = 5.
\(A_2 = \pi (5)^2\\\\A_2= 25 \pi\)
a. The area over which a walkie-talkie can transmit its signal is \(\pi\) miles.
b. The area over which a CB radio signal can transmit its signal is \(25\pi\) miles.
c. The ratio of the transmitted signals are:
\(\frac{CB}{WT} = \frac{25\pi}{\pi} \\\\CB = 25 (WT)\)
Hence, the CB signal transmits 25 times more than the signal transmitted by the walkie-talkie.

The distance the cyclist traveled into the country, given that he rides into the country at an average speed of 10 miles per hour is 15 miles
How do i determine the distance traveled?Let the total distance traveled into the country be y.
Now, we shall determine the riding time. Details below:
Speed = 10 mile per hourDistance traveled = yRiding time = ?Riding time = Distance / speed
Riding time = y / 10
Next, we shall obtain the walking time of the cyclist. This is shown below:
Speed = 3 mile per hourDistance traveled = yWalking time = ?Walking time = Distance / speed
Riding time = y / 3
Finally, we shall obtain the total distance traveled. This is illustrated below:
Riding time = y / 10Riding time = y / 3Total time = 6.5 hoursTotal distance = y =?Total time = riding time + walking time
6.5 = y/10 + y/3
6.5 = (3y + 10y) / 30
6.5 = 13y / 30
Cross multiply
13y = 6.5 × 30
13y = 195
Divide both sides by 13
y = 195 / 13

Una pelota es lanzada horizontalmente desde la azotea de un edificio de 54 m de altura y Llega al suelo a 32 m de la base. Cuál fue la rapidez inicial de la pelota?
The initial speed of a ball thrown horizontally from the roof of a building at a height of 54 m and hitting the ground at a height of 32 m from the bottom is equal to 9.64 m/sec.
A ball throws horizontally from the roof of a building. This is where we have to take horizontal movement into account.
Height of building = 54 m
Height of ground from base = 32 m Calculates the initial speed of the ball.
Since the ball is thrown horizontally, its initial velocity has no vertical component. When released, the ball is subject to gravity and accelerates downward until it hits the bottom. To determine how long the ball stayed in the air before hitting the ground, use the following formula,
d = 1/2×g×t²
where g --> acceleration due to gravity
t --> time
d --> the distance covered by ball before hitting the ground, g= 9.81 m/s².
So, 54 m = (1/2) × 9,81 m/s² × t²
=> t² = 54/4.90
=> t² = 540/49
=> t² = 11.02 sec²
=> t = 3.31963 ~ 3.32 sec
So the ball will stay in the air for about 3.32 seconds. Let v₀ₓ be the horizontal component of the initial velocity. According to the information of the problem, the ball landed 32 m from the bottom of the building. Let's make the initial position x₀ = 0. Then, the final horizontal displacement of a ball will be equals to 32 metres. Using the distance velocity relation, x = x₀ + v₀ₓt and substituting all known values in it,
=> 32 m = 0 + v₀ₓ × 3.32 sec
=> v₀ₓ = 32/3.32
=> v₀ₓ = 9.6385 ≈ 9.64 m/sec
Hence, required value is 9.64 m/sec.

a measurement of the diameter of a disk has an uncertainty of 1.4 mm. how many measurements must be made so that the diameter can be estimated with an uncertainty of only 0.5 mm? round the answer to the next largest integer.
Number of measurements that must be made so that the diameter can be estimated with an uncertainty of only 0.5 mm is 16
To estimate the diameter with an uncertainty of 0.5 mm, we need to reduce the uncertainty to that level. Let's call the number of measurements we need to make "N". We can use the formula for the standard deviation of the mean
σ_mean = σ / sqrt(N)
where σ is the standard deviation of the individual measurements. In this case, the uncertainty of each measurement is given as 1.4 mm, which we can assume is the standard deviation.
To reduce the uncertainty to 0.5 mm, we need
0.5 = 1.4 / sqrt(N)
Solving for N, we get
N = (1.4 / 0.5)^2 = 15.68

The modeling process begins with the framing of a conceptual model that shows the relationships between the various parts of the problem being modeled. This model helps to identify the mathematical correlations between variables and provides a foundation for developing a more detailed and accurate mathematical model.
The modeling process begins with the framing of a mathematical model that shows the relationships between the various parts of the problem being modeled. This model is often based on data analysis and utilizes statistical techniques to establish correlations between the different variables in the problem. Ultimately, the goal of the modeling process is to create a predictive tool that can be used to make informed decisions about the problem at hand.
Process models involve graphically representing processes or functions that capture, manage, store, and distribute information between the system and its environment and physical objects. One type of process model is the flowchart (DFD). A data flow is a diagram that shows the movement of data between external sources and processes and the data stored in the system. While several different tools have been developed for modeling, we focus only on data streams as they are effective tools for modeling.
