The linear equation to represent the value of the car in terms of the year will be c = 64000 - 5000y

An equation simply has to do with the statement that illustrates the variables given. In this case, it is vital to note that two or more components are considered in order to be able to describe the scenario.

In this situation, the upfront cost of a Porsche is 64K and at the end of 12 Years, the car is worth only $4000.

The difference in amount will be:

= $64000 - $4000

= $60000

Number of years = 12

Amount in depreciation per year = $60000 / 12

= $5000 per year

The linear equation to represent the value of the car in terms of the year will be:

c = 64000 - 5000y

where c = value

y = number of years

Therefore , the solution of the given problem of triangle comes out to be √3 ,√4,√5  advance to acute triangle category as they have small angle less than 90 degree.

Given that it has three sides and three vertices, a triangle qualifies as a polygon. It is a fundamental geometric figure. Triangle ABC is the term used to refer to a triangle containing the vertices A, B, and C. When the three points are not collinear, a unique plane and triangle in Euclidean geometry are discovered. Triangles are polygons because they have three sides and three corners. The points where the three sides of the triangle converge are referred to as the triangle's corners. Three triangle angles are multiplied to yield 180 degrees.

Here:

Given :

=> 4 ,4√3,8

The possibility to draw a triangle from mentioned three sides can be checked through SSS or side-side-side rule of triangle. It states that sum of any two sides should be greater than third side of the triangle. Assuming 2.5 cm to be side a, 4.2 and 8 cm to be side b and c respectively.

Side a + side b > side c

2.5 + 4.2 > 8

Add the values

6.7 not greater than 8

Side b + side c > side a

4.2 + 8 > 2

Add the values

12.2 > 2.5

side c + side a > side b

8 + 2.5 > 4.2

Add the values

The average cost per passenger - mile of driving is $0.503 per mile.

Average cost is calculated by dividing the total cost by the total output quantity.

There are two options for Daniel and Elizabeth, either by driving car or by plane.

We have to calculate the average cost per passenger - mile of driving in car.

Cost of gas = $60

Food bill for a day for two of them = $25

Food bill for a day for one = 25 / 2 = $12.5

Food bill for one passenger for 4 days = $12.5 × 4 = $50

Cost of room for 1 night = $48

Cost of room for 4 nights = $192

Total cost for 1 passenger = $60 + $50 + $192 = $302

Average cost per passenger - mile of driving = 302 / 600 = $0.503 per mile.

Hence the average cost per mile per passenger is $0.503 per mile.

Applying the triangle sum theorem, the value of x in the triangle is: C. 36.

The Triangle Sum Theorem states that the sum of the measures of the interior angles of a triangle is 180 degrees. This theorem applies to all triangles, regardless of their shape or size.

The theorem can be proven using the fact that the sum of the measures of the interior angles of any polygon with n sides is (n-2)x180. Since a triangle has three sides, the sum of its interior angles is 180 degrees.

Therefore:

2x + 2x + x = 180

Combine like terms

5x = 180

Divide both sides by 5

5x/5 = 180/5

x = 36

Step-by-step explanation:

In the figure consider the parallelogram is a ABCD parallelogram

A parallelogram is a two-dimensional shape.

It has four sides, in which two pairs of sides are parallel.

Also, the parallel sides are equal in length.

If the length of the parallel sides is not equal in measurement, then the shape is not a parallelogram.

Similarly, the opposite interior angles of a parallelogram should always be equal. Otherwise, it is not a parallelogram.

AB = 3x+5

CD = 5x-9

where AB || CD and AD || BC

Also, AB = CD and AD = BC

then 3x+5 =  5x-9

when simplify the equation,

5x = 3x+5+9

5x = 3x+14

then

     5x-3x = 14

     2x = 14

     x  = 14÷2

     x = 7

then the value of x = 7

when substituting value of x in equations

AB = 3x+5 = 21+5 = 26

CD = 5x-9 = 35-9 = 26

AB = CD

Every coordinate point of the original triangle has its scale factor doubled by one-half if the scale factor is one. multiply by half after dilation with a scale factor of two.

We locate the dilation's center point and measure the distances between it and other points on the preimage and the image in order to get the scale factor for the dilation. As correctly stated by Math Bits Notebook, the scale factor is determined by the ratio of these distances.

Keep in mind that each coordinate must be multiplied by the scale factor in order to enlarge an object in the coordinate plane. The mapping will be (x, y) (1.5 x, 1.5 y) with this dilation.

Step-by-step explanation:

By evaluating the formula for the sequence, we will get the terms:

Here we want to find the second, fourth, and eleventh terms in the sequence:

A(n) = -9 + (n - 1)*3

n defines the "number" of the term in the sequence.

So to get the second term, we need to use n = 2, we will get.

A(2) = -9 + (2 - 1)*3

A(2) = -9 + 3 = -6

The fourth term is what we get if we evaluate in n = 4, then:

A(4) = -9 + (4 - 1)*3

A(4) = -9 + 9 = 0

And the eleventh term is what we get when we use n = 11, we will get:

A(11) = -9 + (11 - 1)*3

A(11) = -9 + 30 = 21

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between. The mathematical operators can be of addition, subtraction, multiplication, or division. For example, x + y is an expression, where x and y are terms having an addition operator in between. In math, there are two types of expressions, numerical expressions - that contain only numbers; and algebraic expressions- that contain both numbers and variables.

e.g. A number is 6 more than half the other number, and the other number is x. This statement is written as x/2 + 6 in a mathematical expression. Mathematical expressions are used to solve complicated puzzles.
