The two positive real numbers with a product of 11 that have the smallest possible sum are √11 and √11. In decimal form, these numbers are approximately 3.3166 and 3.3166.

To determine two positive real numbers whose product is 11 and have the smallest possible sum, we can use the concept of the arithmetic mean-geometric mean inequality.

Let the two numbers be x and y.

We have the following conditions:

1. xy = 11 (product of the two numbers is 11)

2. x > 0, y > 0 (both numbers are positive)

According to the AM-GM inequality, the arithmetic mean of two numbers is always greater than or equal to the geometric mean of those numbers.

Using this inequality, we have:

(x + y)/2 ≥ √(xy)

Substituting the value of xy as 11, we get:

(x + y)/2 ≥ √11

To minimize the sum (x + y), we need to make it as close as possible to the right side of the inequality.

This occurs when equality holds, that is, when:

x = y = √11

So, the answer is approximately (3.3166, 3.3166).

Answer: The area of garden B is 234.8% of the area of garden​ A.

Step-by-step explanation:

Given: Garden A has area 25 square meters. Garden B has area 58.7 square meters.

The percent of the area of garden​ A is the area of garden B =

\(\dfrac{\text{area of garden B}}{\text{area of garden A}}\times100\)

\(=\dfrac{58.7}{25}\times100\%\\\\= 58.7\times4\%\\\\= 234.8\%\)

Step-by-step explanation:

Let's define the step function f(x) that represents the situation:

For 0 ≤ x ≤ 500:

f(x) = 0.30x + 25

For 500 < x < 1000:

f(x) = 0.15x + 100

In this step function, x represents the number of miles driven, and f(x) represents the total cost of renting the truck for that distance. The function has two separate cases based on the mileage range:

- For distances between 0 and 500 miles, the rental fee is $25 plus $0.30 per mile driven. Hence, the equation is f(x) = 0.30x + 25.

- For distances greater than 500 miles but less than 1000 miles, the rental fee is $100 plus $0.15 per mile driven. The equation becomes f(x) = 0.15x + 100.

By using this step function, you can calculate the rental cost for different mileage ranges.

Answer:

y = .3x + 25 {x l if 0 < x < 500}

y = .15x + 100 {x l if 500 < x < 1000}

Step-by-step explanation:

The only thing that I am not sure about is the 500 miles.  For the first part we are told if the miles are between 0 and 500.  500 is not between, so it is not included in the first equation, but it 500 does not appear to be included in the second equation either.  It pertains to miles more than 500.  500 is not more than 500.  So, it looks like 500 miles is not covered in either equation.

The equation that describes the relationship is option A. y = 8 - 7x.

Slope of a line is the ratio of the change in y coordinates to the change in the x coordinates of two points given.

Given are the values of x and y.

x : 0  1  2  3

y : 8  1  -6  -13

Equation of a line can be written as y = mx + d in slope intercept form.

m is the slope and d is the intercept along Y axis.

Slope of a line with two points (x, y) and (x', y') is,

Slope = (y' - y) / (x' - x)

Consider the points (0, 8) and (1, 1).

Slope, m = (1 - 8) / (1 - 0) = -7 / 1 = -7

Since we already have the point (0, 8), y intercept, d = 8.

Substituting these, we get the equation of line as,

y = -7x + 8 or

y = 8 - 7x

Hence the equation of the line is y = 8 - 7x.

The volume of the solid obtained by rotating the region under the curve y = x√(4 − x²) from x = 0 to x = 2 about the y-axis is 32π/15 cubic units.

Let's consider a thin disk or washer-shaped slice of the solid, with thickness Δx and radius y = x√(4 − x²). To find the volume of this slice, we can use the formula for the volume of a disk:

Volume of disk = πr²Δx

where r is the radius of the disk. In this case, the radius of the disk is y = x√(4 − x²), so the volume of the slice is:

Volume of slice = π(x√(4 − x²))²Δx

= πx²(4 − x²)Δx

To find the total volume of the solid, we need to add up the volumes of all of the thin slices. To do this, we can use an integral:

Total volume = ∫[from 0 to 2] πx²(4 − x²) dx

Evaluating this integral gives us the total volume of the solid:

Total volume = π∫[from 0 to 2] (4x² − x⁴) dx

= π[4x³/3 − x⁵/5] [from 0 to 2]

A parking sign is in the shape of a square. The area in square centimeters, is given by the equation: l^(2)=400 The length, l, of one side of the sign is  20 centimeters.

The equation l^2 = 400 represents the relationship between the length of one side of the square (l) and its area. To find the length of one side, we need to solve for l. In this case, we can take the square root of both sides of the equation to isolate l.

Taking the square root of 400, we get l = √400 = 20.

Therefore, the length of one side of the parking sign is 20 centimeters.

By substituting the value of l back into the equation, we can verify that it satisfies the equation: (20)^2 = 400, which is true.

Hence, the length of one side of the square parking sign is 20 centimeters.

the arc length indicated by the bolded arc with a radius of 13 inches and a central angle of 30 degrees is (13π/6) inches.

To find the arc length indicated by the bolded arc with a radius of 13 inches and a central angle of 30 degrees, follow these steps:

Convert the central angle to radians: Since there are 360 degrees in a full circle and 2π radians in a full circle, you can use the conversion factor (π/180) to convert the central angle from degrees to radians. So, 30 degrees * (π/180) = (30π/180) = (π/6) radians.

Calculate the arc length using the formula: Arc length (L) = radius (r) * central angle (θ), where r is the radius and θ is the central angle in radians. In this case, r = 13 inches and θ = π/6 radians.

Substitute the values into the formula: L = 13 * (π/6)

Solve for L: L = (13π/6)

Step-by-step explanation:

The sequence goes up by four.

The covariance for X and Y is -0.56 and the correlation coefficient (rho) for X and Y is -0.03.

To compute the covariance and correlation coefficient, we first need to calculate the expected values of X and Y:

E(X) = Σx P(X = x) = 0(0.03) + 5(0.105 + 0.04) + 10(0.06 + 0.15 + 0.13) + 15(0.02 + 0.10 + 0.01) = 8.25

E(Y) = Σy P(Y = y) = 0(0.03 + 0.04 + 0.01) + 5(0.06 + 0.20 + 0.15) + 10(0.02 + 0.10 + 0.13) + 15(0.01) = 8.25

What is the covariance?

Now we can use the formulas:

Cov(X, Y) = E(XY) - E(X)E(Y)

E(XY) = ΣΣ xy P(X = x, Y = y) = 0(0.03) + 5(0.06 + 0.04) + 10(0.02 + 0.20 + 0.15 + 0.10) + 15(0.13 + 0.02 + 0.01) = 10.05

Cov(X, Y) = 10.05 - (8.25)(8.25) = -0.5625

What is the correlation coefficient?

rho = Cov(X, Y) / (SD(X) SD(Y))

SD(X) = √(V(X)) = √(E(X²) - [E(X)]²)

SD(Y) = √(V(Y)) = √(E(Y²) - [E(Y)]²)

E(X²) = Σx² P(X = x) = 0²(0.03) + 5²(0.105 + 0.04) + 10²(0.06 + 0.15 + 0.13) + 15²(0.02 + 0.10 + 0.01) = 131.25

E(Y²) = Σy² P(Y = y) = 0²(0.03 + 0.04 + 0.01) + 5²(0.06 + 0.20 + 0.15) + 10²(0.02 + 0.10 + 0.13) + 15²(0.01) = 131.25

SD(X) = √(131.25 - (8.25)²) = 4.0386

SD(Y) = √(131.25 - (8.25)²) = 4.0386

rho = -0.5625 / (4.0386 x 4.0386) = -0.0349

The details of the question are;

The transformation that maps triangle ΔKIX unto triangle ΔREM is a rotation.

Please see attached the example drawing of ΔKIX and ΔREM created with MS Excel.

A rotation transformation is a rigid transformation, therefore, the side lengths and shape of triangle ΔKIX is preserved in the image of the triangle, ΔREM

The measure of angle ∠X in triangle ΔKIX is ∠X = 117°

The measure of angle ∠I in ΔKIX is ∠I = 2°

∠K + ∠I + ∠X = 180° (angle sum property  of a triangle)

The measure of angle ∠K = 180° - (∠X + ∠I)

Therefore;

m∠K = 180° - (117° + 2°) = 61°

m∠K = 61°

Based on the naming of the triangles ΔKIX and ΔREM, we have;

∠K corresponds to ∠R, ∠I corresponds to ∠E, and ∠X corresponds to angle ∠R, therefore;

∠K ≅ ∠R, ∠I ≅ ∠E, ∠X ≅ ∠R, which by the definition of congruency indicates;

The subject of your question pertains to chemistry, specifically relating to the concept of pH and its calculation from the hydroxide ion concentration. As the sample of grape juice you mentioned has a hydroxide ion concentration of 1.4 x 10−10 m, we first need to find the concentration of hydronium ions. This can be determined using Kw (the ion product of water) which equals [H3O+][OH-] = 1.0 x 10-14 at 25°C. Given your hydroxide ion concentration, we have [H3O+] = Kw / [OH-], so [H3O+] = (1.0 x 10^-14) / (1.4 x 10^-10) = 7.14 x 10^-5 M.

Now, we can calculate the pH using the formula pH = -log [H3O+]. Substituting the value of [H3O+] into the equation gives pH = -log(7.14 x 10^-5) = 4.15. Rounded to the nearest tenth, this results in a pH value of 4.2 for your grape juice sample.
