The ratio between consecutive terms is (5^(n+1))/[(n+1)*(5^n)]. To find the ratio of the terms in the series, we need to determine the general term (an) of the series.

For the first series, ∑n=1∞ 5^n, we observe that each term is a power of 5. The general term can be expressed as an = 5^n.

For the second series, ∑n=1∞ 5^n/n, we have a combination of the terms 5^n and 1/n. The general term can be written as an = (5^n)/n.

To find the ratio between the terms, we'll calculate the ratio of consecutive terms:

Ratio = (a[n+1])/(an) = [(5^(n+1))/n+1] / [(5^n)/n]

Simplifying the expression, we can cancel out the common factors:

Ratio = (5^(n+1))/[(n+1)*(5^n)]

Rounding 2.079404467 to 1 decimal place means keeping only one digit after the decimal point.

Looking at the second digit after the decimal point, which is 7, we see that it is greater than or equal to 5. Therefore, we round up the first digit after the decimal point, which is 9, by adding 1 to it.

So, rounding 2.079404467 to 1 decimal place, we get:

2.1

Therefore, 2.079404467 to 1 decimal place is equal to 2.1.

Answer:

\(xy=wz\)

Step-by-step explanation:

Given that:

Speed of Wilmer up the hill = \(y\) km/min

Time taken up the hill = \(x\) minutes

Speed of Wilmer down the hill = \(z\)  km/min

Time taken up the hill = \(w\) minutes

Distance can be calculated by multiplying the Speed with Time i.e.

The formula for distance is given as:

\(Distance = Speed \times Time\)

Distance up the hill = \(y\times x =xy\ kilometers\)

Distance down the hill = \(z\times w =wz\ kilometers\)

It is well known that, the distance up the hill and down the hill will be same.

Putting both the values equal, we get:

\(xy=wz\)

Answer:

Step-by-step explanation:

The surface area of that part of the plane 10x+7y+z=4 that lies inside the elliptic cylinder \(\frac{x^2}{25} +\frac{y^2}{9}\) is 15π√150 and this can be determined by using the given data.

We are given the two equations are:

10x + 7y + z = 4---------(1)

\(\frac{x^2}{25} +\frac{y^2}{9} =1-------------(2)\)

equation(1) is written as

z = 4 - 10x - 7y-----------(3)

The surface area is given by the equation:

A(S) = ∫∫√[(∂f/∂x)² + (∂f/∂y)² + 1]dA------------(4)

compare equation(4) with equation(3) we get the values of ∂f/∂x and

∂f/∂y

∂f/∂x = -10

∂f/∂y = -7

substitute these values in equation(4)

A(S) = ∫∫√[(-10)² + (-7)² + 1]dA

A(S) = ∫∫√[100 + 49 + 1]dA

A(S) = ∫∫√[150]dA

A(S) = √150 ∫∫dA

Where ∫∫dA is the elliptical cylinder

From the general form of an area enclosed by an ellipse with the formula;

comparing x²/a² + y²/b² = 1  with x²/25 + y²/9 = 1, from that we get the values of a and b

a = 5 and b = 3

So, the area of the elliptical cylinder = πab

Thus;

A(S) = √150 × π(5 × 3)

A(S) = 15π√150

Answer:

The linear equation is y = 8x + 60

Step-by-step explanation:

the slope-intercept form of the linear equation is

y = m x + b, where

∵ Claire charge a $60 sign-up fee

→ This means it is a fixed amount for a sign-up

∴ b = 60

∵ There is an additional $8 per month

→ This means it is the rate

∴ m = 8

∵ y represents the total cost of her membership in x months

→ Represent this situation by the form of the linear equation above

∴ y = 8x + 60

∴ The linear equation is y = 8x + 60

Given: point (-2, 7)

The given line is perpendicular to the line we are to find.

For a line to be perpendicular to another, the slope of one will be the negative reciprocal of the other slope.

For neither people, we multiply the complement of the probabilities,  hence:

(1 - 0.6) x (1 - 0.4) = 0.24.

For only Mary, we have that:

Given

The current figure is in quadrant II.

Explanation

When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the x-axis is (x, -y).

Solution

Therefore, the figure reflected on the x-axis would be in quadrant III.

The sum of the reciprocals of the two numbers is 0.5

Let the two numbers be x and y such that

x + y = 10

xy = 20

In x + y = 10, x = 10 - y

plugging in in xy = 20

(10 - y)y = 20

10y - y² - 20 = 0

y² - 10y + 20 = 0

solving the quadratic equation gives

y = 2.76 OR 7.24

The total cost predicted for a month with 2,000 units of production  using the equation of the regression line $197,042.

The total cost predicted by Star, Inc. for a month in which production is 2,000 units would be calculated using the equation of the regression line:

y = intercept + (slope * x)

where y is the total cost, x is the production, intercept is the y-intercept (174,182), and slope is the coefficient of production (11.93).

Plugging in the values, we get:

y = 174,182 + (11.93 * 2,000) = 174,182 + 23,860 = 197,042

So the total cost predicted for a month with 2,000 units of production is $197,042.

Each kennel should have dimensions of 35 feet by 45 feet to maximize the total enclosed area if no fencing is needed along the side of the building.

By considering the total area enclosed by all four kennels. Since they are identical, we can just focus on one kennel and multiply by four. Let the length of the kennel "L" and the width "W". We know that the perimeter of the kennel is 2L + 2W = 210 feet. We also know that we don't need any fencing along the side of the building, so one side of the kennel will be the building itself, which has length 120 feet. Therefore, we can write: 2L + W = 210 - 120 = 90

Solving for one variable in terms of the other, we get: L = 45 - 0.5W Now we want to maximize the area enclosed by the kennel. The area of a rectangle is simply length times width, so the area enclosed by one kennel is: A = LW = (45 - 0.5W)W = 45W -\(0.5W^2\)  

To find the maximum area, we can take the derivative of this expression with respect to W and set it equal to zero: dA/dW = 45 - W = 0 Solving for W, we get W = 45. Plugging this back into our equation for L, we get L = 35. Therefore, each kennel should have dimensions of 35 feet by 45 feet to maximize the total enclosed area.

To verify that this gives the maximum area, we can substitute these values into our expression for the area and simplify: A = LW = 35 * 45 = 1575 square feet per kennel. Total area = 4 * 1575 = 6300 square feet.
