Which expression is equilvalent to 2(x+y)+4(x+y)+8(x-y)?

Answer: 42 km of 120km is 35%

Step-by-step explanation: 42 ÷ 120 is 0.35 then you move decimal 2 places right to get percent.

Answer:

x = 2

Step-by-step explanation:

-4x + 136 + 52 = 180             {supplementary  angles}

        -4x + 188 = 180

Subtract 188 from both sides

                -4x = 180 - 188

                -4x = -8

Divide both sides by (-4)

          x = -8/-4

x = 2

4x + 7 + 2x + 5 = 180

6x + 12 = 180

6x = 168

x = 28

The most desirable spaces excluding 7 are 6 and 8 because there are more ways to roll a 6 or 8 than any other numbers except 7.

In the game of Settlers of Catalan, the two most desirable spaces excluding 7 are 6 and 8. These are the most desirable spaces because there are more combinations of numbers that add up to 6 and 8 than any other numbers except 7.

Let's have a closer look at the numbers on each die:

Die 1: 1, 2, 3, 4, 5, 6

Die 2: 1, 2, 3, 4, 5, 6

For the numbers that add up to 6, we have:

1 + 5 = 62 + 4

= 63 + 3

= 64 + 2

= 65 + 1

= 6

For the numbers that add up to 8, we have:

2 + 6 = 83 + 5

= 84 + 4

= 85 + 3

= 86 + 2

= 87 + 1

= 8

The sequence (a) is not convergent. The sequence (b) is convergent.

A sequence is a list of numbers written in a specific order. It is an ordered collection of terms, where each term is associated with a positive integer. Sequences can be defined explicitly or recursively. In an explicitly defined sequence, each term is directly expressed in terms of its index, while in a recursively defined sequence, each term is defined in terms of previous terms in the sequence.

Sequences can be finite or infinite. Finite sequences have a specific number of terms, while infinite sequences continue indefinitely.

The behavior of a sequence can be studied by analyzing its convergence, divergence, monotonicity, boundedness, and other properties.

For sequence (a) aₙ = (2n + 1)/(n + 1):

To determine if the sequence is convergent, we need to check its monotonicity and boundedness.

Monotonicity:
The sequence is increasing because as n increases, the numerator (2n + 1) increases faster than the denominator (n + 1).

Boundedness:
The sequence is not bounded from above since there is no finite number that can serve as an upper bound for the sequence.

Therefore, the sequence (a) is not convergent.

For sequence (b) aₙ = 2ⁿ/n:

To determine if the sequence is convergent, we need to check its monotonicity and boundedness.

Monotonicity:
The sequence is decreasing because as n increases, the numerator (2ⁿ) stays the same while the denominator (n) increases.

Boundedness:
The sequence is bounded from above since for any value of n, the numerator (2ⁿ) will always be greater than the denominator (n).

Therefore, the sequence (b) is convergent.

Answer:its a zero slope or you can do  x2-x1 and y2-y1 and if its an even fraction try simplifying it .

Step-by-step explanation:

The slope of the coordinates is 0.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane. Calculating the slope of a line is similar to finding the slope between two different points. In general, to find the slope of a line, we need to have the values of any two different coordinates on the line.

So, Slope = m = tan θ

slope = (y2 - y1)/(x2 - x1)

given coordinates:

(−5,4) and (2,4)

So, slope = (y2 - y1)/ (x2 - x1)

slope = (4- 4)/ (2 - (-5))

slope = 0 / 7

slope = 0

Hence, the slope of the coordinates is 0.

The general cosine template is

y = A*cos(B(t - C)) + D

where in this case

We only really need to worry about the B value. To get the period T, we do the following

T = 2pi/B

T = (2pi)/(pi/4)

T = 2pi * (4/pi)

T = 8

Note how the pi terms canceled. The period is 8 seconds, which is the length of one full cycle. This is the time it takes for the pendulum to do one full swing (eg: start at the right, swing to the left all the way, then swing back to the right again).

The result of 8 we got has nothing to do with the D = 8 value (this D value could be any other number and T = 8 would still be the case as long as B doesn't change of course).

When a plane passes through the vertex of a double-napped cone, the intersection is a degenerate conic section.

A double-napped cone is formed by rotating a straight line around another straight line that is parallel to it.

The intersection of a plane with a double-napped cone is referred to as a conic section. A degenerate conic section is formed when a plane intersects a double-napped cone at the vertex.

Thus, when a plane passes through the vertex of a double-napped cone, the intersection is a degenerate conic section.

The percentage of men is more than 72 inches tall will be 0.15866.

The z-score is a statistical evaluation of a value's correlation to the mean of a collection of values, expressed in terms of standard deviation.

The z-score is given as

z = (x – μ) / σ

Where μ is the mean, σ is the standard deviation, and x is the sample.

Suppose the mean height for men is 70 inches, with a standard deviation of 2 inches.

Then the percentage of men are more than 72 inches tall will be

z = (72 – 70) / 2

z = 1

The percentage of men is more than 72 inches tall will be

P(x > 72) = P(z > 1)

P(x > 72) = 1 – P(x < 72)

P(x > 72) = 1 – 0.84134

P(x > 72) = 0.15866

Thun, the percentage of men are more than 72 inches tall will be 0.15866.

The Riemann sum is a method used to approximate the value of a definite integral by dividing the interval into subintervals and evaluating the function at specific points within each subinterval.

In this case, we are given the integral ∫30(4x^2 + 2x + 1)dx and we need to find the Riemann sum using right endpoints and n subintervals.

To calculate the Riemann sum, we first need to determine the width of each subinterval. The total interval is 30, and we will divide it into n subintervals, so the width of each subinterval is Δx = 30/n.

Next, we need to determine the right endpoint of each subinterval. Since we are using right endpoints, the right endpoint of the first subinterval will be x_1 = Δx, the right endpoint of the second subinterval will be x_2 = 2Δx, and so on. The right endpoint of the nth subinterval will be x_n = nΔx.

Now, we can calculate the Riemann sum by evaluating the function at each right endpoint and multiplying it by the width of the subinterval. Let's denote the function as f(x) = 4x^2 + 2x + 1.

The Riemann sum can be written as:

R = Σ[f(x_i)Δx], where i ranges from 1 to n.

Using the right endpoints, the Riemann sum can be expressed as:

R = Σ[f(x_i)Δx] = Σ[(4(x_i)^2 + 2x_i + 1)Δx], where i ranges from 1 to n.

Finally, we can calculate the Riemann sum by substituting the values of x_i and Δx into the above expression and summing up the terms.

To determine the concentration of the analyte in the unknown using the fit parameters and the linear model, you need to substitute the given signal value into the equation y = mx + b.

In this case, the linear model is represented by the equation y = mx + b, where:

y is the signal value (80.77 in this case),

m is the slope obtained from the regression analysis, and

b is the y-intercept obtained from the regression analysis.

You haven't provided the values of m and b, so I'll use placeholders for now.

Let's assume the slope (m) obtained from the LINEST formula is m = 2.5 and the y-intercept (b) is b = 10.

Substituting these values into the equation:

y = mx + b

80.77 = 2.5x + 10

To find the concentration (x), we can rearrange the equation:

2.5x = 80.77 - 10

2.5x = 70.77

x = 70.77 / 2.5

x ≈ 28.31

Therefore, based on the given fit parameters and the linear model, the concentration of the analyte in the unknown is approximately 28.31 ppm Co2+.

Distance of 125 feet covered in 5 seconds, so the speed is 25 feet/second.

Any object's distance traveled in a unit of time is referred to as speed.

In mathematical term, Speed is express as S = D/T,

where S=speed, D=distance, T= time.

Given that,

The distance = 125 feet.

The time taken to cover the distance = 5 seconds.

To find the unit rate.

Apply formula,

speed = distance / time

          = 125 / 5
