Demetri lives in the city and sometimes uses a ride share service. A ride costs $1.50 for the first 1/5 mile and $0.25 for each additional 1/5 mile. Demetri does not want to spend more than $3.75 on a ride. So, he must not go beyond 9 miles.

An expression that contains variables, constants, and algebraic operations is defined as just an algebraic expression in mathematics (addition, subtraction, etc.). Terms comprise expressions. A mathematical statement with variables, constants, coefficients, and algebraic operations is known as an algebraic expression.  Terms comprise expressions. Algebraic equations are declarations of the equality of two expressions created by performing the algebraic operations of adding, subtracting, multiplying, dividing, raising to a power, and root extraction to a collection of variables.

Given data

A ride costs $1.50 for the first 1/5 mile.

$0.25 for each additional mile.

Let the number of miles be x

and the cost of x miles be y

Hence the expression for the total cost is

y = 1.5+ 0.25x

now when y = 3.75

or, 3.75 = 1.5 + 0.25x

or, 3.75 - 1.5 = 0.25x

or, 2.25 = 0.25x

or, x = 2.25/0.25

or, x = 9 miles

Hence he must not go beyond 9 miles.

The equation of the secant line containing the points (-7,g(-7)) and (8,g(8)) is

y = (123/15)x + (98 - (123/15) * (-7))

The equation of a line in slope-intercept form is y = mx + b, where m is the slope of the line and b is the y-intercept. To find the equation of the secant line, we need to find the slope (m) and the point of intersection (x,y) of the line with the y-axis.

To find the slope (m) of the secant line, we can use the formula:

m = (y2 - y1) / (x2 - x1)

where (x1,y1) = (-7, g(-7)) and (x2,y2) = (8, g(8)).

So, m = (g(8) - g(-7)) / (8 - (-7)) = (g(8) - g(-7)) / 15

Now, we can substitute the value of g(x) in the above equation and get the value of m

g(x) = 2x^2-7

m = (2(8^2)-7 - 2(-7^2)-7) / 15 = (2(64)-7 - 2(49)-7) / 15 = (128-7-98-7) / 15 = 123/15

To find the point of intersection (x,y) of the line with the y-axis, we can use one of the given points and the slope. Let's use the point (-7,g(-7))

y = mx + b

g(-7) = m * (-7) + b

b = g(-7) - m * (-7)

We can substitute the value of g(x), m and x = -7 in the above equation and get the value of b.

g(x) = 2x^2-7

b = 2(-7)^2-7 - m * (-7) = 2(49)-7 - 123/15 * (-7) = 98 - 123/15 * (-7)

So, the equation of the secant line containing the points (-7,g(-7)) and (8,g(8)) is

y = (123/15)x + (98 - (123/15) * (-7))

Insertion Sort with Binary Search is still a linear time-complexity algorithm in the average and worst case, but it is not the best option for sorting large arrays of elements, as the time complexity remains quadratic.

Insertion Sort is a simple sorting algorithm that works by inserting each element in its correct position in a sorted list.

a. It uses Θ(n²) comparisons in the worst case: This statement is true. In the worst-case scenario, Insertion Sort with Binary Search still takes Θ(n²) comparisons to sort an array of n elements. This happens when the array is sorted in descending order, and the elements need to be inserted one by one at the beginning of the list.

b. It uses Θ(n log n) comparisons in the average case: This statement is false. Insertion Sort with Binary Search still uses Θ(n²) comparisons in the average case, even though the use of Binary Search reduces the number of comparisons compared to Linear Search.

By using what we know about right triangles, we will see that the hobbits are at 744.39 meters from the Dark Tower.

This position can be visualized as a right triangle, with the catheti being the tower's height and the distance between the hobbits and the Dark Tower.

Then we can use the relation:

Tan(θ) = (opposite cathetus)/(adjacent cathetus)

Where θ = 28°

The adjacent cathetus to this angle exists the height of the tower, then:

Adjacent cathetus = 1,400 m

The opposite cathetus exists the distance,

Tan(28°) = D/1,400m

Solving for D we get:

Tan(28°)*1,400m = D = 744.39m

The hobbits are at 744.39 meters from the Dark Tower.

Area of circle A = pi r²

r is the radius

small circle area = pi

large circle area = k.pi

the diameter of the the large circle equals 3 times the diameter of the small circle .

since A = pi . r²

pi.r² = pi as given the area of the small circle

r²= 1

r= 1 is the radius of the small circle the the diameter = 2

the diameter of the large circle = 3.2 = 6

the radius = 3

the area = pi .3² = 9 pi

then k = 9

The function h(x) can be expressed as a composition of two other functions: f(x) and g(x).

In mathematics, functions are a way to describe relationships between variables.

The function f(x) is defined as 2 raised to the power of x. This means that for any value of x, the output of the function f(x) will be 2 raised to that power.

If x is 3, then f(3) = 2³ = 8.

The function g(x) is defined as x. This means that the output of the function g(x) will be the same as its input.

If x is 4, then g(4) = 4.

Combining these two functions, we can express h(x) as f(g(x) + 6). This means that for any value of x, the output of h(x) will be 2 raised to the power of g(x) plus 6.

If x is 2, then g(2) = 2, and

=> h(2) = f(g(2) + 6) = f(8) = 2⁸ = 256.

In summary, the function f(x) raises 2 to the power of x, and the function g(x) returns its input.

By combining these two functions, we can express h(x) as the result of 2 raised to the power of g(x) plus 6.

What are simultaneous linear equations?

Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.

Here,

On the given graph there are two lines intersecting at points (-1, 1), since the point of intersection of the two lines represents the solution to both equations.

Thus, (-1, 1) is the required ordered pair that represents a solution to both equations.

Step-by-step explanation:

1. The solution of a system of 3 simultaneous linear equations in three variables are (2, 3, 1).

2. The base of the mathematical constant e, an irrational and transcendental number roughly equal to 2.718281828459, is the natural logarithm of a number.

1. A system of 3 simultaneous linear equations in three variables are

5x - 4y + 2z = 0.............(1)

-3x + 4y = 6.............(2)

x + 4z = 6.............(3)

We solve these system of equations using the substitution method and elimination method.

Add equation (1) and (2)

5x - 4y + 2z + (-3x + 4y) = 0 + 6

5x - 4y + 2z - 3x + 4y = 0 + 6

After the elimination the equation is:

2x + 2z = 6

Taking common 2 and divide by 2 on both side, we get

x + z = 3................(4)

Subtract equation 3 and 4

x + 4z - (x + z) = 6 - 3

x + 4z - x - z = 3

3z = 3

Divide by 3 on both side, we get

z = 1

Now putting the value of z in equation 4

x + 1 = 3

Subtract 1 on both side, we get

x = 2

Now putting the value of x in equation 2

-3(2) + 4y = 6

-6 + 4y = 6

Add 6 on both side, we get

4y = 12

Divide by 4 on both side, we get

y = 3

Now the solution of system of equation is (2, 3, 1).

2. The exponent or power that must be added to a base to produce a particular number is called the logarithm. If bx = n, then the mathematical expression for x is x = logb n, where x is the logarithm of n to the base b.

What is vector ?

A vector is a mathematical object that has both magnitude (or length) and direction. Vectors can be used to represent physical quantities such as velocity, force, or displacement, where the magnitude represents the size of the quantity and the direction represents its orientation in space.

The range of t(x) = ax, where a = 1 −3 0 5 3 1, is the set of all possible values of t(x), which is the set of all linear combinations of the columns of the matrix a. To check if y = (4, 9) is in the range of t(x), we need to see if there exists a vector x such that t(x) = y. If a vector x exists, then y = (4, 9) is in the range of t(x). If no such vector exists, then y is not in the range of t(x).

Since the columns of a are linearly dependent, we can conclude that y = (4, 9) is not in the range of t(x).

Answer:

My answer to your question is a "No".

We can know that a and b are the same numbers. If we multiply the same number on each side, the answer will be the same. However, x and y have different values. So, it will show differently.

Let's have an example:

It we say a = 5, x = 6, y = 7.

We know a and b are the same number so, both a and b will be 5. If we multiply a by x, it will be 5 x 6 which is 30. It will show the same answer on multiplying b because as you said a and b are the same. The equation will be 5(a) x 6(x) = 5(b) x 6(x) Let's look at multiplying y. If we multiply a by y, it will be 5 x 7 which is 35. As you said it will show the same answer on multiplying b because a and b are the same. The equation for this will be 5(a) x 7(y) = 5(b) = 7(y). Finally, let's compare the two equations.

5(a) x 6(x) = 5(b) x 6(x) -> 30 = 30

5(a) x 7(y) = 5(b) = 7(y) -> 35 = 35

You can see it more clearly when we compare those to the equations that I made.

Thank you

Yes, if a = b, then ax = bx and ay = by for any value of x.

This is because the equation a = b implies that a and b are equal in value, so any expression involving a can be replaced with an equivalent expression involving b. In other words, any operation performed on a can be performed on b and produce the same result.

For example, if a = b, then multiplying both sides of the equation by x yields ax = bx, and multiplying both sides of the equation by y yields ay = by. This means that any power, root, logarithm, or other mathematical operation performed on a can also be performed on b and produce the same result.
