Given m \| nm∥n, find the value of x.

95$

Step-by-step explanation:

Based on the given conditions, formulate ( 1100 - 720 ) ÷ 4

Calculate the sum or difference = 380/4

Cross out the common factor = 95

To find the greatest common factor of these three terms, we need to factor each one and identify the highest power of each factor that is common to all three. Then, we can multiply those factors together to find the GCF.

Let's begin by factoring each term:

1/4n^2m^3 = (1/4) * n^2 * m^3

5/20n^7m^8 = (1/4) * n^7 * m^8

3/12n^2m^8 = (1/4) * n^2 * m^8

Now, we can see that each term has a common factor of 1/4, so we can factor that out:

1/4 * (n^2 * m^3)

1/4 * (n^7 * m^8)

1/4 * (n^2 * m^8)

To find the highest power of each factor that is common to all three terms, we need to look at the exponents. The highest power of "n" that is common to all three terms is 2, and the highest power of "m" that is common to all three terms is 3. Therefore, the GCF is:

1/4 * n^2 * m^3

This simplifies to:

n^2m^3/4

So, the correct option is (c) n^2m^3/4.

The longest segment that can be drawn to connect two vertices is 10 cm

From the question, we have the following parameters that can be used in our computation:

Represent the smallest length with x

So, we have

SA = 2 * (x(x + 1) + x(x + 2) + (x + 1)(x + 2))

Substitute the known values in the above equation, so, we have the following representation

2 * (x(x + 1) + x(x + 2) + (x + 1)(x + 2)) = 484

So, we have

(x(x + 1) + x(x + 2) + (x + 1)(x + 2)) = 242

When solved using a graph, we have

x = 8

So, we have

Longest edge = 8 + 2

Longest edge = 10

Hence, the longest segment that can be drawn to connect two vertices is 10 cm

Answer:

[tex]x=\dfrac{\ln \left(\frac{21}{25}\right)}{\ln 6125}[/tex]

Step-by-step explanation:

Given equation:

[tex]2 \cdot 5^{3x+2} = 6 \cdot 7^{1-2x}[/tex]

Divide both sides of the equation by 2:

[tex]\implies 5^{3x+2} = 3 \cdot 7^{1-2x}[/tex]

Take natural logs of both sides:

[tex]\implies \ln \left(5^{3x+2}\right) = \ln \left(3 \cdot 7^{1-2x}\right)[/tex]

[tex]\textsf{Apply the product law:} \quad \ln xy=\ln x + \ln y[/tex]

[tex]\implies \ln 5^{3x+2} = \ln 3 + \ln 7^{1-2x}[/tex]

[tex]\textsf{Apply the power law:} \quad \ln x^n=n \ln x[/tex]

[tex]\implies (3x+2)\ln 5 = \ln 3 + (1-2x)\ln7[/tex]

Expand:

[tex]\implies 3x\ln 5+2\ln 5=\ln 3+\ln7-2x\ln7[/tex]

Collect the terms in x on the left side and the constants on the right side of the equation:

[tex]\implies 3x\ln 5+2x\ln7=\ln 3+\ln7-2\ln 5[/tex]

Factor out the common term x on the left side:

[tex]\implies x(3\ln 5+2\ln7)=\ln 3+\ln7-2\ln 5[/tex]

[tex]\textsf{Apply the power law:} \quad n \ln x=\ln x^n[/tex]

[tex]\implies x(\ln 5^3+\ln7^2)=\ln 3+\ln7-\ln 5^2[/tex]

Simplify:

[tex]\implies x(\ln 125+\ln 49)=\ln 3+\ln7-\ln 25[/tex]

[tex]\textsf{Apply the product law:} \quad \ln x + \ln y=\ln xy[/tex]

[tex]\implies x(\ln (125 \cdot 49))=\ln (3\cdot 7)-\ln 25[/tex]

[tex]\implies x(\ln 6125)=\ln 21-\ln 25[/tex]

[tex]\textsf{Apply the quotient law:} \quad \ln x - \ln y=\ln \left(\dfrac{x}{y}\right)[/tex]

[tex]\implies x(\ln 6125)=\ln \left(\dfrac{21}{25}\right)[/tex]

Divide both sides of the equation by ln 6125:

The company can expect to earn $5 per product sold if they offer a warranty, compared to an expected loss of $13 per product sold if they do not offer a warranty. It is a profitable decision for the company to offer the warranty.

In a binomial probability distribution, the number of "Successes" in a series of n experiments is represented as either success/yes/true/one (probability p) or failure/no/false/zero (probability q = 1 p), depending on the outcome's boolean value.

Assuming that the failure of the flagship product follows a binomial distribution with a probability of 1% of failure within 2 years of purchase, let's calculate the expected cost to the company without a warranty and with the warranty.

Without the warranty, the expected cost to the company is given by:

Expected cost without warranty = 0.01 x $1300 = $13

With the warranty, the expected cost to the company is given by:

The time taken by Amy to travel to the place was t = 4 hours.

A measure of average speed is the amount of distance travelled in a given amount of time. It is determined by dividing the overall mileage by the overall time required to cover that mileage.

In physics and other sciences, average speed is frequently employed to describe how objects move. For instance, it is possible to estimate how long it will take to go a certain distance or assess a car's fuel economy by looking at its average speed over a given distance. By dividing the whole distance travelled by the total time required, average speed may also be used to characterise the speed of an object that is moving at various speeds at different points along its path.

Let the time taken to get back = t + 1.

Now, it took one hour less time to get there thus time = t.

Now, average speed is given as:

average speed = total distance / total time

Substituting the values:

50 km/h = d / t

d = 50t  .........(1)

40 km/h = d / (t + 1)

d = 40(t + 1)......(2)

Setting the value of d as equal we have:

50t = 40(t + 1)

50t = 40t + 40

10t = 40

t = 4

Hence, the time taken by Amy to travel to the place was t = 4 hours.

The answer of the given question based on the plotting graph , the steps are given below .

An inequality is a statement that compares two values or expressions and indicates that one is greater than, less than, or equal to the other. Inequalities can be solved or simplified using various algebraic techniques, such as adding, subtracting, multiplying, or dividing both sides by the same quantity, or factoring and finding the roots of the expressions

To plot the inequality 4x - 5y ≤ -15, you can follow these steps:

4x - 5y ≤ -15

-5y ≤ -4x - 15

y ≥ (4/5)x + 3

Let's choose x = 0 and x = 5.

When x = 0: y = (4/5)(0) + 3 = 3, so one point is (0, 3).

When x = 5: y = (4/5)(5) + 3 = 7, so another point is (5, 7).

Plot these two points and draw  straight line through them.

4x - 5y ≤ -15

4(0) - 5(0) ≤ -15

0 ≤ -15

Since this is not true, the point (0,0) is not in the region that satisfies the inequality. Shade the region above the boundary line to show the region that satisfies the inequality.

An inequality is a comparison that shows that one value or expression is larger than, less than, or equal to another. Different algebraic methods, such as adding, subtracting, multiplying, or dividing both sides by the same amount, or factoring and determining the roots of the equations, can be used to resolve or simplify inequalities.

Plotting the inequality 4x - 5y ≤-15 can be done by doing the following:

To solve for y, rearrange the inequality first:

4x - 5y ≤ -15

-5y ≤ -4x - 15

y ≥ (4/5)x + 3

You are then provided with the boundary line's equation. Plot two points on a graph, then draw a straight line through them to represent this line. You can use the equation to determine the values of y that correspond to any two x values to plot the line.

Let's choose x = 0 and x = 5.

When x = 0: y = (4/5)(0) + 3 = 3, so one point is (0, 3).

When x = 5: y = (4/5)(5) + 3 = 7, so another point is (5, 7).

Plot these two spots and a line should be drawn directly between them.

Now select a point that is not on the border line to shade the area that satisfies the inequality. (0, 0) is the simplest position to select. In the inequality, replace the x and y values of this point.

4x - 5y ≤ -15

4(0) - 5(0) ≤ -15

well, the outermost point of the rectangle is 8 points away from the x-axis. when we rotate this rectangle, that attribute remains, of course. and every point on the side surface of the resulting cylinder has the same distance from the central x-axis : 8.

so, the radius is 8.

Answer:

Step-by-step explanation:

The Conjugate Roots Theorem states that imaginary roots come in pairs. If -8i is a root of the polynomial, then so is +8i.

If both -8i and +8i are factors, we rewrite them as (x + 8i) and (x - 8i) in factored form. Since imaginary terms aren't accepted, you can FOIL these to get a quadratic with no imaginary terms.

x2 - 8ix + 8ix - 64i2

Simplify. Replace i2 with -1 because √-1 = i

x2 - 64(-1)

x2 + 64

The quadratic x2 + 64 has roots -8i and 8i. You can use the quadratic formula to verify this.

Now, let's tackle the rest of the polynomial. If x2 + 64 is a factor of the polynomial

x4 + 10x3 + 85x2 + 640x + 1344, divide it out to see what is left. I will use long division of polynomials. Note, I am using the square root symbol as a division symbol.

x2 + 10x + 21

x2 + 64 √ (x4 + 10x3 + 85x2 + 640x + 1344)

x4 + 64x2

_____________

10x3 + 21x2

10x3 + 640x

__________

21x2 +1344

21x2 + 1344

___________

0

There is no remainder, meaning x2 + 64 went in evenly. The quotient left when we divide out x2 + 64 from

x4 + 10x3 + 85x2 + 640x + 1344 is x2 + 10x + 21. Factor the quotient to get (x + 7)(x + 3).

x4 + 10x3 + 85x2 + 640x + 1344 = (x2 + 64)(x + 7)(x + 3)

You can check this factored form by FOILing out, and you should get the original polynomial.

Answer:

Step-by-step explanation:

you have to match the numbers on the lines of the plane, they have to match up with each other it goes (x,y) the x line is the one going to the side, and the y is the one going up to down

The probability of selecting a car from the rental parking lot is 0.6 or 60%.

Probability of selection refers to the likelihood or chance of selecting a particular item or event from a group or population. It is a mathematical concept used in statistics, mathematics, and science to describe the likelihood of an event occurring, given the set of possible outcomes.

The probability of selecting a car from the rental parking lot can be found by dividing the number of cars by the total number of vehicles:

P(Car) = Number of Cars / Total Number of Vehicles

In this case, there are 5 trucks, 9 cars, and 1 van, so the total number of vehicles is:

Total Number of Vehicles = 5 + 9 + 1 = 15

Number of Cars = 9

Therefore, the probability of selecting a car from the rental parking lot is:

P(Car) = Number of Cars / Total Number of Vehicles

           = 9 / 15

           = 3 / 5

            = 0.6

So the probability of selecting a car from the rental parking lot is 0.6 or 60%.
