What number can be multiplied to the equation to make it so the x's are eliminated.
- 8x + 2y = 8
4x + 3y = -4

One-half of the dogs in each shelter are between the weights represented by the first and third quartiles, which are approximately 20-55 pounds for the first shelter and 25-65 pounds for the second shelter, respectively.

A box plot is a visual representation of a set of data that shows the median, quartiles, and outliers of the data. The box represents the middle 50% of the data, with the bottom and top edges of the box representing the first and third quartiles, respectively. The line inside the box represents the median, or the middle value of the data set. The "whiskers" extend from the edges of the box to the minimum and maximum values of the data set, but outliers beyond the whiskers are represented as individual points.

Now, let's look at the two box plots showing the weights of dogs in two different animal shelters. One-half of the dogs in each shelter are between the first and third quartiles, which are represented by the edges of the box in each plot.

If we take the first box plot, we can see that the first quartile is approximately 20 pounds and the third quartile is approximately 55 pounds. Therefore, one-half of the dogs in this shelter weigh between 20 and 55 pounds.

The radius of convergence, R, of the series is \($R=\infty$.\)

Here's the solution for the given problem.

In this case, we have a power series of the form:

\($$\sum_{n=1}^{\infty}a_n(x-c)^n$$\)

In order to determine the radius of convergence of this series, we use the ratio test.

The ratio test states that if \($\lim_{n\rightarrow\infty}\frac{a_{n+1}}{a_n}=L$,\)

then the series converges if \($L<1$ and diverges if $L>1$. If $L=1$,\)the test is inconclusive.

Now, let's apply the ratio test to our series:\($\lim_{n\rightarrow\infty}\frac{a_{n+1}}{a_n}=\lim_{n\rightarrow\infty}\frac{5^{n+1}(x+3)^{n+1}}{(n+1)5^nn(x+3)^n}=\lim_{n\rightarrow\infty}\frac{5(x+3)}{n+1}=0$\)

Therefore, the series converges for all values of \($x$\)

Since the radius of convergence is the largest interval about \($c$\) for which the series converges, the radius of convergence is\($\infty$.\)

Answer:

They have 36 books in total.

Step-by-step explanation:

Let d = The number of Dima's books

Let r = The number of Ramiro's books.

d = 2r

d - 12 = r Substitute 2r for d in the second equation and solve for r

2r - 12 = r   Subtract 2r from both sides

2r - 2r - 12 = r - 2r

-12 = -r  Multiply both sides by -1

12 = r

Ramiro has 12 books.

d = 2r substitute 12 for r and solve for d

d = 2(12)

d = 24

Dima has 24 books.

Together they have 36 books (12 + 24)

Answer:36

Step-by-step explanation:

To linearize the given differential equations, we need to find the linear approximation of the nonlinear terms. In the first equation, the linearization involves finding the first derivative of y with respect to t, while in the second equation, we use logarithmic differentiation to linearize the nonlinear term. In both cases, the linearized equations help approximate the behavior of the original nonlinear equations.

a) To linearize the equation dy/dt + zy = r, we can write the linearized equation as d(y - y0)/dt + z(y - y0) = r - r0, where y0 and r0 are the values of y and r at a specific point. This linearization approximates the behavior of the original equation around the point (y0, r0). The linearization involves finding the first derivative of y with respect to t.

b) To linearize the equation dy/dt + ay + By^2 + yln(y) = Q, we can use logarithmic differentiation. Taking the natural logarithm of both sides of the equation, we get ln(dy/dt) + ln(y) + ln(a) + ln(B) + yln(y) = ln(Q). Then, we differentiate both sides with respect to t, resulting in 1/(y^2) * (dy/dt) + (1/y) * (dy/dt) + (1/y) * y + 0 + yln(y) * (dy/dt) = 0. This linearization allows us to approximate the behavior of the original nonlinear equation by neglecting higher-order terms.

In both cases, the linearized equations provide a simpler representation of the original equations, making it easier to analyze their behavior and approximate solutions.

We first would need to figure out what 20% of $37.35 is.

0.2 (or 0.20) × 37.35 = 7.47

This means that the discount price is $7.47

Now subtract that from the total.

37.35 - 7.47 = 29.88

Therefore, his total in dollars and cents after the discount and before tax is twenty-nine dollars and eighty-eight cents.

Step-by-step explanation:

"Centripetal is the word used to describe a vector that always points toward the centre of a circular path."

The centripetal acceleration vector is an acceleration in the radial direction that is directed towards the centre of the circular line of motion. It runs perpendicular to the linear motion, or v.

The direction of the velocity shift for a ball travelling around a curve is in the direction of the curve's centre. Centripetal acceleration is the acceleration that is directed towards the centre of a curved or circular route.

Any force that changes the path of motion towards the centre of a circular motion is known as a centripetal force. The portion of the force that produces the centripetal force is the part that is perpendicular to the velocity.

Answer:

x = y = 20

Step-by-step explanation:

The two triangles shown are similar because one is simply an extension of othe other.

From this, we can use a similar side lengths formula specifically for triangles.

\(\frac{y + 5}{y} = \frac{15}{12}\\\)

Notice that this represents the ratio of the whole side to the smaller side and says that this proportion is equal to the proportion for its adjacent side lengths. Cross mutiply the above equation to solve for y.

12(y+5) = 15y

12y + 60 = 15y

y = 20

Now we need to find the value of x. We have a side and hypotenuse's length of this large triangle, so we can use the pythagorean theorem to calculate the unknown side length.

(12 + 3)² + x² = (20 + 5)²

15² + x² = 25²

225 + x² = 625

x² = 400

x = ±20

The negative 20 doesn't make sense for this application so use the positive 20.

Therefore x = 20, y = 20.

The appropriate choice that identifies the hypothesis test in this scenario is:

a. independent group means, population standard deviations and/or variances unknown

In this case, we are comparing the mean weight loss between two different groups (powder diet and liquid diet) that are independent of each other. The population standard deviations are known, but the population variances are not explicitly mentioned. However, since the standard deviations are given, we can assume that the variances are also known.

Answer:

Step-by-step explanation:

In the formula provided, A(r) = 2(rh) + 2r², r is the length of one side of the square base. The derivative of A(r) is A'(r) = -1000000/r² + 4r, and the value of r that makes this derivative zero is r = 50∛2. The second derivative of A(r) is A''(r) = 2000000/r³ + 4. A''(50∛2) = 80/∛2 is positive, indicating that the value of r that makes A(r) a minimum is r = 50∛2.

First, the dimensions of the box that minimize the amount of material used can be determined using the surface area formula. The volume of the box is given as: V = lwh = (r)(r)(h) = r²h = 500000 cm³Hence, h = (500000/r²) cm. The surface area of the box can be found as: A(r) = 2lw + lh + wh = 2(rh) + r² + r²A(r) = 2(rh) + 2r². Substituting the value of h found above, A(r) = 2(r[(500000)/(r²)]) + 2r² = (1000000/r) + 2r². The derivative of A(r) is: A'(r) = -1000000/r² + 4r. Equating A'(r) to 0 to obtain the critical point: -1000000/r² + 4r = 0. Multiplying both sides by r² gives: -1000000 + 4r³ = 0. 4r³ = 1000000. Thus, r³ = 250000. r = 50∛2.

To verify that this is indeed a minimum value for the surface area, we find the second derivative of A(r): A''(r) = 2000000/r³ + 4. Plugging r = 50∛2 into the second derivative formula gives: A''(50∛2) = 2000000/(50∛2)³ + 4 = 80/∛2. Since A''(50∛2) is positive, this confirms that A(r) = (1000000/r) + 2r² is minimized when r = 50∛2.

We have:

After 5 hours the pool filled with 230 gallons

Let's suppose that after x hours the pool will fill with 920 gallons

After x hours the pool filled with 920 gallons.

As the water input contained at a constant rate

So the value of x can be evaluated:

\(\rm x = \frac{920\times5}{230}\)

x = 20 hours
