Carmen is planning rail lines for a new train station. Help her find m1. Explain how you found that solution.

The required equation is:

1. d = 81t

2. f(t) = 81t

Now, According to the question:

Given that a car moving at a constant speed passed a timing device at t=0.

In other words, at t = 0 second, d = 0 ft.

We know that

distance = rate × t

After 7 ​seconds, the car has traveled 567 ft.

In other words, at t = 7 seconds, d = 567 ft

Thus, there are two points

(0, 0)

(7, 567)

Finding the slope between (0, 0) and (7, 567)

Using the formula

Slope = Rate of change = [y₂-y₁] / [x₂-x₁]

                                       = [567 - 0] / [7-0]

                                       = 567 / 7

                                       = 81 ft./second

Given that the car is moving at constant speed. So, we don't have any other factor or term to consider

Thus, the required equation is:

distance = rate × t

d = 81 × t

d = 81t

or

f(t) = 81t

VERIFICATION

Given the equation

d = 81 × t

Put t = 0 to find the distance in 1 sec

d = 81 × (0) = 0 ft.

Put t = 7 to find the distance in 7 seconds

d = 81 × (7) = 567 ft.

The graph of the given function is attached below.

A relationship between a group of inputs and one output is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.

The graph of the function y = -2log2(x+3) + 2 is a downward-sloping curve that approaches the x-axis as x approaches infinity.

The curve is defined only for positive values of x, as the logarithm is undefined for negative values.

As x increases, the logarithm term inside the parentheses becomes larger in magnitude, causing the value of y to decrease rapidly.

The curve approaches the x-axis but never touches it, as the logarithm term will never reach zero.

Answer: x = 25

Step-by-step explanation:
2x-10 = x+15
x = 15+10

x=25

The required value of x in the given triangle is 25, evaluated by following the definition of angle bisectors.

Given that, MNO is a triangle, where OP is the angle bisector, in the given scenario we have to determine the value of the x.

Following the definition of an angle bisector, the angle bisector for any angle bisects the angle into two equal halves, So,
Angle PNO = Angle PMO
2x-10=x+15

Simplify the above expression to evaluate x.
2x-10=x+15
2x-x=15+10
x=25

Thus, the required value of x in the given triangle is 25, by following the definition of angle bisectors.

We can use trigonometry to solve this problem.

the sine of the angle is equal to the side opposite the angle divided by the hypotenuse

so we have [tex]sin(x)=\frac{19}{26}[/tex]

now, in order to get x by itself, we have to take the inverse sine of both sides.

[tex]x=sin^{-1} (\frac{19}{26} )[/tex]

now we can plug this into a calculator.

we get 46.95 degrees

a₃ - a₂ = 4/5 - 2 = -6/10 = -3/10

As the common difference is not same, it is not an AP.

Check for GP:

a₁  = 5

a₂ = a₁ q²⁻¹

a₂ = 5q = 2

a₃ = a₁q³⁻¹

    =  a₁q²

a₃ = 5q² = 4/5

As,

a₂/ a₁ = 2/5

a₃/a₂ = 2/5, it is an GP

We have to reflect over x- axis to transform parallelogram ABCD to create A'B'C'D'.

A point, line, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object. Pre-Image refers to the object's initial shape, and Image, after transformation, refers to the object's ultimate shape and location.

Given:

The Coordinates of ABCD are:

A( -4, 1), B(-3, 2), C(-1, 2) and D(-2, 1)

and,  Coordinates of A'B'C'D' are:

A'( 4, -1), B'(3, -2), C'(1, -2) and D'(2, -1)

Now, Reflection over the x-axis.

A"(-4, 1)- 2(0, 1) ---> A"( -4, -1)

B"(-3, 2) - 2(0, 2)----> B"(-3, -4)

C"(-1, 2)-2(0, 2)--->C"(-1, -2)

D"(-2, 1)- 2(0,1)--->D"(-2, -1)

To dilate a triangle with center points we multiply the coordinates of the points in the preimage by the scale factor to determine the points in the image.

What is a scale factor?

A scale factor is a numerical value that is used to represent an object's larger or shrunk shape. It is a number that can be used to alter the size of any geometric figure or shape in relation to its initial size. It aids in altering the figure's size but not its shape.

Here,

we have to determine how we dilate a triangle with center points.

We concluded that

The origin is often used as the center of dilation. If you are dilating a figure centered at the origin, you can multiply the coordinates of the points in the preimage by the scale factor to determine the points in the image.

If 4 cm and 7 cm are the lengths of two sides of a triangle then the length of the third side should be 6 cm.

In the given question we have to check 4 cm and 7 cm are the lengths of two sides of a triangle then the length of the third side may be.

Any two sides of a triangle can have a sum of lengths that is always greater than the length of the third side.

Any two triangle sides' length differences will never be greater than the triangle's third side's length.

The sum of 4cm and 7cm is 11cm, and their difference is 3cm.

The third side's possible length must be larger than 3 cm and less than 11 cm to ensure that the aforementioned rule is not broken.

6 cm is therefore larger than 3 cm and less than 11 cm from the possibilities presented.

From the provided value of the paid price of the car and sales tax percentages, The answer is $564.

Percentages are a way to express a number as a part of 100. The symbol for percentage is %. For example, 25% means 25 out of 100, or one quarter. To convert a percentage to a decimal, divide it by 100. For example, 25% = 25/100 = 0.25. To convert a decimal to a percentage, multiply it by 100. For example, 0.25 = 0.25 * 100 = 25%. You can also calculate percentage by multiplying the number with the percentage rate. For example, if you want to find out what 25% of 50 is, you can calculate it by multiplying 50 by 0.25 (since 25% is the same as 0.25 as a decimal).

Tax is a financial charge imposed by a government on individuals, businesses, and other entities. The revenue generated by taxes is used to fund government programs and services such as infrastructure, education, healthcare, and defense. There are many types of taxes, including income tax, sales tax, property tax, and capital gains tax. The specific tax that a person or entity is required to pay depends on the jurisdiction and the type of activity or transaction involved. Tax laws and rates can vary widely between countries and even within a country.

The least common denominator (LCD) of 3/4 and 5/6 is 12

To discover the least common denominator, list the multiples of both denominators until you find the smallest multiple that both denominators share. Because 20 is the first shared multiple of 4 and 5, it must be the fractions’ least common denominator.

The least common denominator (LCD) of a group of fractions is the least common multiple (LCM) of their denominators.

In this case, the denominators of the fractions are 4 and 6. The least common multiple (LCM) of 4 and 6 is 12. Therefore, the least common denominator of 3/4 and 5/6 is 12.

You can also find the LCM by finding the prime factorization of the numbers, and then take the highest power of each prime factor and then multiply those.

[tex]4 = 2^2\\6 = 2*3[/tex]

The highest power of 2 and 3 are [tex]2^2[/tex] and 3 respectively, so LCM(4,6) = [tex]2^2 * 3 = 12[/tex]

All values of z are negative numbers less than -5, which are -6, -7 and -8 so on.

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

Given that, the opposite of z is greater than 5.

So, we have the following absolute value inequality.

|z|>5

This can be written as z>5 or z<-5

5 is a positive number.

So, we make use of the inequality z<-5.

From the above inequality, the possible values of z are -6 and -7

Step-by-step explanation:

The angles are a pair of linear angles. They complement one another and are close by. They intersect at a right angle. x = 33,

When two straight lines or rays intersect at a single endpoint, an angle is created. The vertex of an angle is the location where two points come together. The Latin word "angulus," which means "corner," is where the term "angle" originates.

Additional angles add up to 180.

(x-17)+(5x-1) = 180

x-17+5x-1 = 180

(x+5x)+(-17-1) = 180

6x-18 = 180

6x = 180+18

6x = 198

x = 198/6

x = 33

Additional information

x = 33, therefore if

x-17 = 33-17 = 16
