The length of the shorter arc from vertex P to vertex N is 37.68 inches.

In a two-dimensional plane, a polygon is a closed object formed of line segments rather than curves. Polygon is a word that combines the words poly (which means numerous) and gon (which means sides).

To create a closed figure, at least three line segments must be connected end to end.

Given an equilateral polygon, PENTA is inscribed in a circle of radius 15 inches,

The central angle of the polygon leaning to the shortest chord is

α = 2π/5

α = 2*360/5 = 72°

The central angle of the polygon leaning to the shorter arc from vertex P to vertex N is

β = 2(2π/5)

β = 144°

The length of the corresponding arc is

= r*β

here r = 15 inches, and π = 3.14

length = r*2*2π/5

length = 15*2*2(3.14/5)

length = 37.68 inches.

Hence length is 37.68 inches.

The rate of change picking the apples is 8 bushels of apples per hour.

Rate of change is used to mathematically describe the percentage change in value over a defined period of time, the formula for rate of change is: R = (D2 - D1)/T. where: R = rate of change.

Given that, you and your best friend are picking apples at a local orchard. there were already 12 bushels of apples on the tractor when you began at 8:00 am and you picked apples until noon, we are asked to find, what was your rate of change if there were 44 bushels filling the tractor when you stopped,

So, the rate change = total apples picked in 8 am to noon / number of hours.

Therefore, the total apples picked in 8 am to noon =

Since, it was 44 bushels at the end and when they started there were already 12 bushels, so the number of bushels of apples filled between given hours = 44 - 12 = 32 bushels.

The number of hours in picking 32 bushels of apples = 12 noon - 8 am

= 4 hours

Therefore,

The rate of change = 32 / 4

= 8

Hence, the rate of change picking the apples is 8 bushels of apples per hour.

The coordinates of the orthocenter of the triangle are (-1. 1.2)

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

L(-4,3), M(2,3), and N(-1,-2).

Calculate the slopes of LM and LN.

So, we have

m₁ = (3 - 3)/(2 + 4) = 0

m₂ = (-2 - 3)/(-1 + 4) = -5/3

The slopes of the lines perpendicular to the above slopes is

m₁ = -1/0 = undefined

m₂ = -1/(-5/3) = 0.6

Next, calculate the equation of lines passing through M in which the height perpendicular to LN lay

(y - yM) = m₁(x - xM)

y - 3 = 0.6(x - 2)

Next, calculate the equation of lines passing through undefined slope

x = -1

Substitute x = -1 in y - 3 = 0.6(x - 2)

y - 3 = 0.6(-1 - 2)

Correct answer is H, On solving the provided question, we can say that inequality is graphed below is X less than/equal to x ≤ 15

A relationship between two expressions or values that is not equal in mathematics is referred to as an inequality. Thus, inequity results from imbalance. In mathematics, an inequality establishes the connection between two non-equal numbers.

Egality and inequality are not the same. Use the not equal symbol most frequently when two values are not equal ().

Values of any size can be contrasted using a variety of inequalities. By changing the two sides until only the variables are left, many straightforward inequalities can be solved.

However, a variety of factors support inequality: Both sides' negative values are split or added. Exchange the left and the right.

Answer: The expression (q + 1)^2 is equal to q^2 + 2q + 1.

The expression (q + 1)^2 can be expanded as follows: (q + 1)^2 = q^2 + 2q + 1. The "2" at the top of the parentheses is the exponent, meaning the expression inside the parentheses is being raised to the power of 2.

Step-by-step explanation:

Answer:

The variable "y" is a placeholder for a value in mathematics and can represent many different things depending on the context. To find the value of y, you need to know the equation or expression that relates y to other variables. For example, if y = 2x + 1, then y is equal to the sum of 2 times the value of x and 1. To find the value of y for a particular value of x, you would substitute the value of x into the equation and solve for y.

In general, the value of y can represent anything from a dependent variable in an equation to a coordinate on a graph. To determine what y represents in a specific context, you need to understand the context and the equation or expression that defines y.

Answer:

Step-by-step explanation:

The equation 12sec²x - 16 = 0 is not a quadratic equation, as it does not have a standard form of ax^2 + bx + c = 0.

To solve for x, we need to isolate sec²x by adding 16 to both sides and then dividing by 12:

12sec²x - 16 + 16 = 0 + 16

12sec²x = 16

sec²x = 16 / 12

sec²x = 4/3

Now that we have isolated sec²x, we can find x by finding the inverse secant of 4/3.

Note that the inverse secant is a multi-valued function, so there may be multiple solutions for x.

The feet the bicycle will it cover in 30 seconds is 306 feet

When we talk about speed, it is often expressed in miles per hour (mph). However, in this problem, we must determine the distance covered in feet per second. To convert mph to feet per second, we can use the following formula:

1 mph = 5280 feet/hour = 5280/3600 feet/second

Therefore, to convert 14 mph to feet per second, we multiply 14 by the conversion factor of 5280/3600:

14 mph * (5280/3600 feet/second/mph) = 14 * 5280/3600 feet/second = 10.2 feet/second

So, the bicycle is traveling at a speed of 10.2 feet per second. To find the distance covered in 30 seconds, we multiply the speed by the time:

10.2 feet/second * 30 seconds = 306 feet

Finally, rounding to the nearest tenth of a foot, we have:

306 feet ≈ 306.0 feet to the nearest tenth.

Answer: The area of the triangle is given by the formula:

Area = (base * height) / 2

We are told that the area is less than 18 square inches, so we can write the inequality:

(base * height) / 2 < 18

Multiplying both sides by 2, we get:

base * height < 36

To find the possible values of "a", we need to isolate "base" on one side of the inequality. Let's assume that the base is equal to "a". Then we have:

a * height < 36

Dividing both sides by height, we get:

a < 36 / height

Since the height is 6 inches, we can substitute it in the inequality:

a < 36 / 6 = 6

So the possible values of "a" are any value less than 6 inches. That is,

0 < a < 6.

Step-by-step explanation:

The  required solution to the system of equations using elimination, as follows:

18. The solution is (x, y) = (40/11, -17/11).

19. The solution is (x, y) = (6, 1).

The equation is defined as a mathematical statement that has a minimum of two terms containing variables or numbers that are equal.

To solve the system of equations using elimination, we can multiply one equation by a scalar so that one of the variables has the same coefficient in both equations.

18.

-6x + 4y = -28

6x + 7y = 11

Add the two equations to eliminate x:

11y = -28+11

11y = -17

y = -17/11

Now that y is known, we can substitute back into either equation to find x:

-6x + 4(-17/11) = -28

-6x - 68/11 = -28

x = 40/11

So the solution is (x, y) = (40/11, -17/11).

19.

2x + 3y = 15

x - 3y = 3

Add the two equations to eliminate y:

3x = 18

x = 18/3

x = 6

Now that x is known, we can substitute back into either equation to find x:

2(6) + 3y = 15

12 + 3y = 15

3y = 3

x = 1

So the solution is (x, y) = (6, 1).
