The sum of the exterior angles of the given polygon is 360°.

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 means sides. To create a closed figure, a minimum of three line segments must be connected end to end.

Given that,

There is a polygon that has 4 sides.

Since, a polygon having 4 sides is called a quadrilateral, and the sum of the interior angle of the quadrilateral is 360°.

The sales of Brawny will remain unchanged, as the amount of Brawny has not changed.

Price is one of the factors that influence the demand and sales of any product. Therefore, when the price of a product changes, the sales of that product may be impacted. However, when the price of one product changes, the sales of another product that has not changed in price may remain unaffected. In this case, since the price of Viva has increased from $2.50 to $2.60, while the amount of Brawny has remained unchanged, the sales of Brawny will likely remain unchanged.

At t = 0.6, the instantaneous velocity of the bug is equal to the average velocity of the bug on [0,6], so the bug is neither speeding up nor slowing down.

The instantaneous velocity of a bug at any particular moment in time is the rate at which the bug is changing its position. The average velocity of the bug over a particular interval (in this case, [0,6]) is the average rate at which the bug changes its position over the entire interval. To compare the instantaneous velocity to the average velocity, the two velocities need to be measured at the same time.

At t = 0.6, the instantaneous velocity of the bug is equal to the average velocity of the bug on [0,6]. That means that the bug is neither speeding up nor slowing down.

A variable in mathematics is a symbol that designates a mathematical object. A variable can represent any of the following: a number, a vector, a matrix, a function, its argument, a set, or an element of a set. An unknown numerical value in an equation or algebraic expression is represented by a symbol (often a letter) in algebra. A variable is, to put it simply, a quantity that may be altered and is not fixed. Because they make up a significant portion of mathematics, variables are crucial.

The distance from work station 1 to work station 3 is 13 feet.

The figure shows the distance between workstation. The figure represents a right angle triangle.

The distance from work station 1 to work station 3 can be calculated as follows:

using Pythagoras's theorem,

c² = a² + b²

where

Therefore, the distance from work station 1 to work station 3 is the hypotenuse side of the right triangle.

Hence,

5² + 12² = c²

25 + 144 = c²

c² = 169

c = √169

c = 13 ft

Let the base and height of triangle be b and h.

area of triangle= 1/2*base*height

Area of triangle= bh/2

Now Base is Doubled and Height increase by 30%

New base = 2b

New height = h×130/100 = 13h/10

New area = 1/2 × 2b × 13h/10

New area = 13bh/10

Area increased = New area - area

Area increased = 13bh/10 - bh/2

Area increased= 13bh-5bh/10

Area increased= 8bh/10

Area increased= 4bh/5

ratio increased in % = Area increased/ Old Area × 100

According to the information in the graph, the blend of foods that satisfies the requirements at the minimum cost is option A because it would be worth only 10.

To calculate the cheapest blend of food option, we must take into account the amounts of each element (carbohydrate, protein, fat) and identify how many units of each blend we need to cover the minimum quota.

Based on the above information, to identify the blend units we need to cover the minimum quota we must find it by multiplying each of the elements by the number of times we would need to meet the minimum requirement. Once we identify the quantities we need, we must multiply the price by the number of units we need.

Following the previous procedure, we can identify that the best option would be blend A because we must buy it 5 times to cover the minimum requirements. Additionally, its value would be 10, while the others would have a higher value.

The equation of the perpendicular line is (c) y = 2/9x - 1

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

y + 17 = -9/2(x - 3)

Also, from the question;

We have the following points

Point = (0, -1) i.e.  (x, y) = (0, -1)

The equation of a line can be represented as

y - y₁ = m(x - x₁)

Where

Slope = m

By comparing the equations, we have the following

m = -9/2

This means that the slope is -9/2

The slopes of perpendicular lines are opposite reciprocals

This means that the slope of the other line is 2/9

The equation of the line is then calculated as

y = m(x - x₁) +y₁

Where

m = 2/9

(x₁, y₁) = (0, -1)

So, we have

y + 1 = 2/9(x - 0)

Evaluate

y = 2/9x - 1

Hence, the line has an equation of y = 2/9x - 1

To find the simple interest rate that Savannah is being charged, we can use the formula for simple interest:

I = P * r * t

where I is the total interest paid, P is the principal (the amount borrowed), r is the interest rate, and t is the time period over which the interest is paid.

Since Savannah must pay back the $2,900.00 principal plus a $1,375.00 fee, the total interest paid is $1,375.00. The time period is 8 months, which is equal to 8/12 = 2/3 of a year. Substituting these values into the formula and solving for r, we get:

$1,375.00 = $2,900.00 * r * (2/3)

r = $1,375.00 / ($2,900.00 * (2/3)) = 0.1429

This is the interest rate that Savannah is being charged. To express this rate as a percentage, we can multiply it by 100% to get:

r = 0.1429 * 100% = 14.3%

Therefore, Savannah is being charged a simple interest rate of approximately 14.3%.

Since, U = FY(Y) is uniform distribution (i.e. U(0, 1)).

In the given question, suppose continuous random variable Y has cumulative distribution function FY (y), and density function fY (y) > 0.

Let random variable U = FY (Y ).

We have to find the density function of U, and identify its distribution (name and parameter(s)) if possible.

A random variable Y has cumulative distribution function FY (y).

A random variable Y has density function f(y).

Let U = FY(Y)

Now we have to find the density function of U using cumulative distribution function method

FU(u) = P(U≤u)

FU(u) = P(FY(Y) ≤ u)

FU(u) = P(Y ≤ F (u))

FU(u) = FY(F (u))

FU(u) = u

fU(u) = F'U(u).1

fU(u) = 1

fU(u) = 1,     0<u<1

Here U = FY(Y) is uniform distribution (i.e. U(0, 1)).

The rate at which the area of the forest is increasing, in square kilometers per decade, is 0.0041.

What does the rate of change mean?

How quickly one variable changes in relation to another is known as the rate of change. Speed is an example of a "rate of change." Speed is defined as the rate at which the distance to an object varies in relation to the time spent.

It is given that there are 640 acres in 1 square mile which can also be written as  640 acres= 1[tex]mi^2[/tex].

The area of forest is increasing at a rate of 1 acre/decade.

It is given that 1 km= 0.62mi

By squaring on both sides we will get 1 [tex]km^2[/tex] = 0.3844 [tex]mi^2[/tex].

The rate at which the area of forests is increasing in square kilometers per decade is

[tex]\frac{1acre}{decade} *\frac{1mi^2}{640acre} *\frac{1km^2}{0.3844mi^2} =0.00406478\frac{km^2}{decade}[/tex] .

A proportion is a gathering of consecutively requested numbers an and b communicated as a/b, where b is never equivalent to nothing. At the point when two items are equivalent, a proclamation is supposed to correspond.

The variable 'y' is directly proportional to the 'x'. Then the equation is given as,

y ∝ x
