The circumference of a circle with a radius of 18 feet is 113.04 ft.

The distance around the circle's edge is referred to as the circumference. It is a basic characteristic of a circle and is incorporated into a number of geometric and trigonometric calculations.

C = 2πr, where C is the circumference, is a mathematical constant, and r is the circle's radius, is the formula for calculating a circle's circumference. An irrational number is one that contains an endless number of decimal places and cannot be stated as a ratio of integers. However, the value of is roughly 3.14 for the majority of practical purposes.

The circle's radius in the provided situation is 18 feet. We can use pi = 3.14 to determine the closest approximation for the circumference of this circle.

C = 2πr = 23.1418 = 113.04 feet.

Answer:

To find the percent of change, we can use the following formula:

(New Value - Old Value) / Old Value x 100

In this case, the new value is $315,000 and the old value is $180,000.

So the percent of change is:

($315,000 - $180,000) / $180,000 * 100

This evaluates to:

$135,000 / $180,000 * 100 = 0.75 * 100 = 75%.

Therefore, the percent of change is 75%.

well, the change or difference was 315000 - 180000 = 135000.

if we take $180,000 (origin amount) to be the 100%, what's 135,000 off of it in percentage?

Answer:

4.2 units

Step-by-step explanation:

To find the length of the arc, we can use the relationship between the length of an arc, the radius of the circle and the measure of the angle in radians. This relationship is:

arc length = (angle in radians) * (radius)

In this case, the radius is 2 and the angle in radians is 2.1. So we can substitute these values into the equation:

arc length = (2.1) * (2)

arc length = 4.2

So the length of the arc is 4.2 units to the nearest 10th

The required average increase in the number of students enrolled per hour are 120 students.

A function of time is anything that can be described by a mathematical equation that varies reliably over time. Over time, a moving object's position changes. The location is said to be a function of time if it fluctuates in a way that can be mathematically predicted.

The function appears to be f(x) = 4. (x - 1).

You can find out how many pupils are registered at hours 2 and 4 using that function.

At hour two, there are f students enrolled (2),

f(2) = 4^ (2 - 1) = 4

At hour four, there are f students enrolled (4),

f(4) = 4^(4 - 1) = 4^3 = 64

The average growth is therefore [64 - 4] students / [4 - 2] hours = 60

students / 2 hours = 30 pupils every hour.

The numbers are as follows if the function is f(x) = 4(x - 1) rather than f(x) = 4x - 1.

f(2) = 4^2 - 1 = 16 - 1 = 15

f(4) = 4^4 - 1 = 256 - 1 = 255

The average growth rate is (255 - 15) / (4 - 2) = 240 / 2 = 120 pupils per hour.

The area of the minor sector is 33.33 cm^2 and the area of minor segment is 53.27 cm^2.

A chord of a circle is a straight line segment that connects any two points on the circumference of the circle.

The area of the major sector can be found by using the formula:

Area of major sector = (Angle of sector / 360) * π * r^2

Where the angle of sector is 120°, and the radius of the circle is 10cm.

So the area of the major sector = (120/360) * π * (10 cm)^2 = (1/3) * π * 100 cm^2 = 33.33 cm^2

To find the area of the minor segment, we need to find the area of the minor sector and then subtract it from the area of the triangle formed by the center of the circle, the midpoint of the chord, and the endpoint of the chord.

The area of the minor segment = area of the triangle - area of the minor sector

As the angle subtended by the chord is 120°, the minor sector will subtend an angle of (360-120) = 240°.

So the area of the minor sector = (120/360) * π * (10 cm)^2 = (2/3) * π * 100 cm^2 = 33.33 cm^2

The area of the triangle can be found by using the formula:

Area of the triangle = (1/2) * b * h

Where b is the distance between the center of the circle and the midpoint of the chord and h is the length of the altitude drawn from the center of the circle to the chord.

So the area of the minor segment = (1/2) * (10cm) * (10cm) * sin(120/2) -33.33 cm^2 = 50*sqrt(3) - 33.33 cm^2=53.27 cm^2

Therefore, the area of the minor sector is 33.33 cm^2 and the area of minor segment is 53.27 cm^2.

$32,250 must be paid back at the end of the 5-year period if the loan is paid in full.

Compounding is the method through which interest is added to both the principle balance already in place and the interest that has already been paid. Thus, compounding can be thought of as interest on interest, with the result that returns on interest are magnified over time, or the so-called "magic of compounding."

A = P * (1 + rt)

Where A is the amount to be paid back, P is the principal amount borrowed (28,000), r is the interest rate (3.25%), t is the number of years (5), and t is the time period in years.

So, plugging in the values, we have:

A = 28,000 * (1 + 0.0325 * 5) = 28,000 * (1 + 0.1625) = 28,000 * 1.1625 = 32,250

Parallel: y= -(7x/3)-20

Perpendicular: y= 3x/7 - 24/7

Step-by-step explanation:

Slope of parallel line: -7/3

So the equation is y=-7x/3+a

Solve for A:

−6=(−7/3)⋅(−6)+a

So A is -20 and the equation is y=-7x/3=20

Slope of perpendicular line: 7/3

So the equation is y=3x/7 + a

Solve for A:

-6=(3/7)*(-6)+a

Therefore, a= -24/7

So the equation is y= 3x/7 - 24/7

Answer:

Equation of the parallel line: [tex]y = -\frac{7}{3}x - 20[/tex]

Equation of the perpendicular line: [tex]y = \frac{3}{7}x - \frac{24}{7}[/tex]

Step-by-step explanation:

To find the equation of a parallel line, we already know that the slope is the same as the original line, so let's find the equation of our original line. We are given:

-7x - 3y = 5

So, we will add 7x to both sides to leave y on a side by itself:

-3y = 7x + 5 (This is the slope-intercept form which is what we will be using)

Then, divide by -3 to isolate y, giving us:

[tex]y= -\frac{7}{3} x - \frac{5}{3}[/tex]

Since it is a parallel line, our slope is the same, giving us:

[tex]y = -\frac{7}{3}x + b[/tex]

Now, the slope of a line is [tex]\frac{rise}{run}[/tex]. Rise is the gain in y, and run is the gain in x. So, since we want to find the y-intercept, we need x to be 0, so let's say for every 3 we gain on the x-axis, we lose 7 on the y-axis (because we need one of the two values to have a negative so that our overall fraction is negative). Now, since we have the point (-6, -6) We need to gain 6 on the x-axis. Meaning, we need to use our slope twice. This means that we will need to also multiply our -7 by 2. So we have:

(-6 + 6, -6 - 14)

Giving us:

(0, -20)

Which is our y-intercept. So our equation for the parallel line is:

[tex]y = -\frac{7}{3}x - 20[/tex]

Now, for the perpendicular line, we need to get the negative reciprocal of the slope of our original line. Our original line's slope was [tex]-\frac{7}{3}[/tex]. So, the negative reciprocal of that is [tex]\frac{3}{7}[/tex]. So, our equation is:

[tex]y = \frac{3}{7}x + b[/tex]

Now, we will find the y-intercept. Since we need to gain 6 on the x-axis, but we have a normal gain of 7, we will need to multiply both our run and rise (3 and 7 respectively) by [tex]\frac{6}{7}[/tex]. Giving us that our x coordinate is:

[tex](-6 + 7 * \frac{6}{7} , -6 + 3 * \frac{6}{7} )[/tex]

Simplifying gives us:

[tex](-6 + 6 , -6 + \frac{18}{7} )[/tex]

Adding the x coordinates gives us:

[tex](0, -6 + \frac{18}{7})[/tex]

Now, to make this simple, we will put -6 over 7. To achieve this, we will need to multiply -6 by 7, giving us -42. So, we have:

[tex](0, -\frac{42}{7} + \frac{18}{7})[/tex]

42 - 18 = 24. So, we get:

[tex](0, -\frac{24}{7})[/tex]

So, the slope of the perpendicular line is:

[tex]y = \frac{3}{7}x - \frac{24}{7}[/tex]

So, these are the two equations of the parallel and perpendicular lines respectively:

Parallel: [tex]y = -\frac{7}{3}x - 20[/tex]

Perpendicular: [tex]y = \frac{3}{7}x - \frac{24}{7}[/tex]

What is an equivalent ratios?

A ratio compares two quantities named as antecedent and consequent, by the means of division. For example, when we cook food, then each ingredient has to be added in a ratio. Thus, we can say, a ratio is used to express one quantity as a fraction of another quantity.

Two ratios are equivalent to each other if one of them can be expressed as the multiple of the other. Hence, to get the equivalent ratio of another ratio, we have to multiply the two quantities (antecedent and consequent) by the same number.

Given ratios are 2:1 and 3:1

we can write it as 2/1 and 3/1.

The lcm of 2 and 3 is 6.

Multiply denominator of both ratio with 6, we get

2/6 and 3/6 And we can see both the ratios are not equal.

Hence, there are not equivalent ratios.
