Following the steps below, what is the next step in constructing a line perpendicular to a segment? Start with a line and point K on that line. Set the compass's width to a medium setting. The actual width does not matter. Without changing the compass's width, mark a short arc on the line at each side of the point K, forming the points P and Q. These two points are the same distance from K because you did not change the width of the compass. ? Using the straight edge, draw a line from K to where the arcs cross. Without changing the compass's width, repeat from the point Q so that the two arcs cross each other, creating the point R. From P, mark off a short arc above K. Increase the compass to almost double the width (the exact setting is not important).

Answer: The new value of the sum of N1,500 investment at a simple rate of 15% per annum for 2 years is N1950

Step-by-step explanation:

Simple interest is calculated by multiplying the principal amount, interest rate, and time.

The formula for simple interest is:

Simple Interest = (principal x rate x time) / 100

In this case, the principal amount is N1,500, the interest rate is 15% per annum and the time is 2 years.

So the simple interest earned on the investment is:

Simple Interest = (1500 x 15 x 2) / 100

Simple Interest = N450

To find the new value of the investment, we add the simple interest earned to the principal amount.

New value = Principal + Simple Interest

New Value = 1500 + 450

New Value = N1950

Explanation: Simple interest is calculated by multiplying the principal amount, interest rate, and time. By using this formula, the interest earned on the investment was N450. And by adding the interest to the principal amount, we can find the new value of the investment which is N1950.

Compound interest is when you earn interest on both the money you've saved and the interest you earn.

The amount earned or paid after compounded interest is given as A = P(1+r/100)^t

Where P is the principal saved

t is the time for saving

and r is the rate of interest

Here t = 28 years

P = 25,000

and r = 5.63% per annum

therefore A = P(1+r/100)^t

A = 25000(1+5.63/100)^28

A = 25000(1+0.0563)^28

A = 25000(1.0563)^28

A = 25000× 4.635

A= $115875.00

Answer: To find the values of k for which the line y = x + k is tangent to the circle x^2 + y^2 = 25, we need to substitute y = x + k into the equation of the circle and solve for x.

x^2 + (x + k)^2 = 25

Expanding the square, we get:

x^2 + x^2 + 2xk + k^2 = 25

2x^2 + 2xk + k^2 = 0

Now we can solve for x by using the quadratic formula:

x = (-b ± √(b^2 - 4ac)) / 2a

Where a = 2, b = 2k and c = k^2

x = (-2k ± √(4k^2 - 42k^2)) / 2*2

x = (-k ± √(-3k^2)) / 4

Since the square root of a negative number is not a real number, we can see that there is no real value of x that will make the equation true. Therefore, the line y = x + k is never tangent to the circle x^2 + y^2 = 25

Answer:

Step-by-step explanation:

To find the values of k that will make the line y = x + k tangent to the circle x^2 + y^2 = 25, we need to set the equation of the line equal to the equation of the circle and solve for k.

First, we'll substitute y = x + k into the equation of the circle:

x^2 + (x + k)^2 = 25

Next, we'll expand the square on x + k:

x^2 + x^2 + 2xk + k^2 = 25

Now we'll combine like terms:

2x^2 + 2xk + k^2 = 25

We'll rearrange the equation so that x^2 is on one side

2x^2 + 2xk + k^2 - 25 = 0

Now we'll divide by 2

x^2 + xk + k^2/2 - 25/2 = 0

Now we'll complete the square

x^2 + xk + (k^2/2 - 25/2) = 0

x^2 + xk + (k^2/2 - 25/2) + (25/2) = (25/2)

(x + k/2)^2 = 25/2

Now we'll take the square root of both sides

x + k/2 = +-sqrt(25/2)

Now we'll solve for x

x = sqrt(25/2) - k/2 or x = -sqrt(25/2) - k/2

Now we'll substitute these values of x into the equation y = x + k and find the value of k.

x = sqrt(25/2) - k/2

y = x + k

y = sqrt(25/2) - k/2 + k

y = sqrt(25/2)

x = -sqrt(25/2) - k/2

y = x + k

y = -sqrt(25/2) - k/2 + k

y = -sqrt(25/2)

So the line y = x + k is tangent to the circle x^2 + y^2 = 25 when k = sqrt(25/2) or k = -sqrt(25/2)

The required distinct roots of the following equation using the quadratic formula is x = -3±√5i.

Any quadratic problem can be solved using the quadratic formula.

The equation is first changed to have the form ax2+bx+c=0, where a, b, and c are coefficients.

After that, we enter these coefficients into the following formula: (-b(b2-4ac))/(2a).

So, the quadratic formula:

x = -b±√b²-4ac/2a

Now, insert values and calculate for roots as follows:

x = -b±√b²-4ac/2a

x = -b±√b²-4*4(1)*14/2(1)

x = -b±√36/56/2

x = -b±√-20/2

Discriminant: b² - 4ac < 0

Now,

x = -6± 2√5i/2

x = -6/2 ± 2√5i/2

x = -3±√5i

Therefore, the required distinct roots of the following equation using the quadratic formula is x = -3±√5i.

Todd's conclusion is therefore incorrect, not all linear relationships are proportional, they can be represented by a linear equation but they don't need to have a constant ratio between the two variables.

What is a linear relationship?

A linear relationship is a relationship between two variables in which the change in one variable is directly proportional to the change in the other variable. Linear relationships can be represented by a linear equation, which is an equation that can be written in the form of y = mx + b, where m and b are constants.

Proportional relationships also have a constant ratio between the two variables, but the relationship between the variables is not always linear. Proportionality can be represented by the equation y = kx, where k is a constant.

In general, it is not true that all linear relationships must be proportional. While it is true that a proportional relationship will always result in a linear graph, there are also many other types of linear relationships that do not fit this definition. For example, the equation y = 2x + 3 describes a linear relationship, but it is not proportional because the ratio between y and x is not constant.

Hence, Todd's conclusion is therefore incorrect, not all linear relationships are proportional, they can be represented by a linear equation but they don't need to have a constant ratio between the two variables.

equate each factor to zero and solve for x

obviously multiplying any value by - 2 will not give zero

Let x be the time (in hours) it takes Meredith to edit a textbook alone. We know that Phil takes 4x hours to edit a textbook alone, since he takes four times as long as Meredith.

We also know that it takes them 16 hours to edit a textbook together. We can use this information to set up the equation:

x + 4x = 16

5x = 16

x = 16/5

So it takes Meredith 16/5 hours to edit a textbook alone.

We know that Phil takes 4x to edit a textbook alone, so we can substitute in the value we found for x to find his time:

4x = 4(16/5) = 16/5 * 4 = 64/5

So it takes Phil 64/5 hours to edit a textbook alone.

Answer:

To calculate the number of yards of ribbon Christine bought, we need to determine how much money she spent on the ribbon. We know that the card had $20 on it initially and that $18.42 was left on the card after her purchase, so we can subtract the remaining balance from the original balance to find out how much she spent:

$20 - $18.42 = $1.58

We also know that the ribbon was 14 cents per yard, so we can divide the amount spent on the ribbon by the price per yard to find out how many yards Christine bought:

$1.58 / $0.14 = 11.285714285714286

So, Christine bought 11.285714285714286 yards of ribbon.

7/9

Step-by-step explanation:

Simplify the following:

(2/3)/(6/7)

Multiply the numerator by the reciprocal of the denominator, (2/3)/(6/7) = 2/3×7/6:

(2×7)/(3×6)

2/6 = 2/(2×3) = 1/3:

7/(3×3)

3×3 = 9:

Answer:7/9

To evaluate x/y for x = 2/3 and y = 6/7, you need to substitute these values into the expression x/y and simplify the result.

x/y = (2/3) / (6/7)

To simplify the fraction, you can cross multiply the numerator and denominator by 7, which is the denominator of the second fraction:

(2/3) / (6/7) = (2/3) * (7/6) = (27) / (36) = 14/18

The fraction can be simplified further by dividing both the numerator and denominator by their greatest common divisor (GCD) which is 2:

14/18 = (14/2) / (18/2) = 7/9

So x/y = 7/9 when x = 2/3 and y = 6/7

It's important to note that the result is a fraction, if you want to express it as decimal you can divide 7 by 9 or use a calculator to get 0.7777 repeating.

The triangle ABC seems to be an scalene triangle since all of the sides AB, BC and CA have different lengths, and also the triangle is not a right angled triangle.

A scalene triangle is a type of triangle in which all three sides have different lengths. In other words, none of its sides are of equal length. As a result, all three angles in a scalene triangle are also different. It is different from an Isosceles triangle, where at least two sides are of equal length and an equilateral triangle where all sides are of equal length.

A right triangle is a type of triangle in which one angle is a right angle (90 degrees). This makes it different from other types of triangles such as acute triangle and obtuse triangle. The side opposite to the right angle is called the hypotenuse, and the other two sides are called legs. The Pythagorean theorem states that in a right triangle, the sum of the squares of the lengths of the legs is equal to the square of the length of the hypotenuse. This theorem is used to determine if a triangle is a right triangle or not.

The triangle ABC is a scalene triangle, as its sides have different lengths.

To determine whether it is a right triangle, we can use the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the lengths of the two shorter sides (legs) is equal to the square of the length of the longest side (hypotenuse).

To find the side lengths, we can use the distance formula, which is

d = √((x2 - x1)² + (y2 - y1)²)

AB = √((9 - 6)² + (3 - 6)²) = √(3² + (-3)²) = √18 = 3√2

BC = √((9 - 2)² + (3 - 2)²) = √(7² + 1²) = √50 = 5√2

AC = √((2 - 6)² + (2 - 6)²) = √(4² + 4²) = √32 = 4√2

We know that in a right triangle, one of the side should be the hypotenuse and the other two should be the legs. We can check if any one of the side is satisfying that. But in this case, we can see that none of the sides are satisfying that condition, therefore the triangle ABC is not a right triangle.

This is the most widely used queuing system in analytics. M/M/1 is a good approximation for a large number of

mass service systems. The M/M/1 quening system assumes a Poisson arrival process. This assumption is a very good approximation for the process of arriving at real systems that satisfy the following rules,

We have, customer service is every 4 minutes. So, the Service rate μ = 1 customer/4 minutes = 0.25 customer/minute or 15 per hour.

Customers arrive individually at a rate of one customer every 5 minutes according to the distribution of poisons.

Number of customer service= 1

The arrival rate is 1/ (mean time between arrivals) . Here, the rate of arrival of customers/5 minutes is λ = 0.2 customers/min or 12 per hour. Therefore,

Utilization factor = (arival rate /service rate)100 = λ/μs

Utilization factor = (12/15) 100%

= (4/5)100 = 80%

Utilization factor = 80%

Average number in the system = λ/( μ - λ)
