Step-by-step explanation:

Step-by-step explanation:

I assume this actually is

revenue : R(x) = 12x

cost : C(x) = 5x + 20

profit : P(x) = R(x) - C(x) = 12x - 5x - 20 = 7x - 20

We have the following:

We can calculate the angle by means of the trigonometric cosine ratios, as follows:

Therefore the angle formed is 57.6 degrees

In the quadratic equation f(x) = a(x - h)² + k , then the graph is given on the right

f(x) = [tex]-2 (x- 3)^{2} + 8[/tex]

According to the question, given that

the quadratic equation f(x) = a(x - h)² + k

Axis of symmetry : x = h = 3

The coordinates of the highest point is (3,8)  {it is the ordinate of the    highest point of the image}

so, k = 8

f(x) =  [tex]a (x- 3)^{2} + 8[/tex]

plug in (0,- 10)

       - 10 = 9a + 8

          a  = - 2

f(x) = [tex]-2 (x- 3)^{2} + 8[/tex]

Therefore, f(x) = a(x - h)² + k quadratic equation we get the value of f(x),

f(x) = [tex]-2 (x- 3)^{2} + 8[/tex]

A polynomial function with one or more variables, where the largest exponent of the variable is two, is referred to as a quadratic function. It is also known as the polynomial of degree 2 since the greatest degree term in a quadratic function is of second degree. A quadratic function must have at least one second-degree term. It performs algebraic operations.

The parent quadratic function connects the locations whose coordinates have the type f(x) = x2 and is of the kind (number, number2). This function, which normally has the form f(x) = a (x - h)2 + k, is capable of being transformed. It can also be changed to take the form f(x) = ax2 + bx + c.

Since Vito's bid is the highest, he gets the bus and has to compensate the others to make the division fair. The amount of money that Tim get from Vito is: $1,581.25.

Fair shares:

Rob: 3600 4 = 900

Sue: 5000 /4 = 1250

Tim: 4800 / 4 = 1200

Vito: 6500 / 5 = 1625

Since Vito gets the bus the amount he pay the group is:

Amount = 6500 - 1625

Amount = 4,875

Since everybody gets their fair share, the amount remaining is:

Amount left = 4,875 - 900 - 1250 - 1,200

Amount left = 1,525

Hence,

The amount Tim get is calculated as :

Amount = 1200 + (1525 /4)

Amount  = $1,581.25

Therefore Tim get $1,581.25.

Using the given linear functions, it is found that:

a) The test average for your math class after completing test 2 is of 76.6.

b) The test average for your science class after completing test 2 is of 84.

c) The science class had a higher average after completing test 4.

The grades change by a constant rate in each of the classes, science and math, hence the functions are called linear.

The average grade function, after x tests, for each class, is defined according to the following rule:

After the second test, the numeric values for items a and b are found replacing the lone instance of x in each equation by 2, hence the grades are as follows:

After the fourth test, the grades are given as follows:

80 > 77.2, hence the science class had a higher average.

The science class grade after test x is given by the following rule:

The best estimate of the cost of renting a car if you plan to drive 268 miles is 234.72 or round off to 235 dollars.

There must be an equal sign (=) in an equation. You can imagine an equation as having a left side and a right side since there will be a mathematical expression on either side of it. Unknowns are a necessary part of algebraic equations. A symbol, such as x, y, or z, is used to symbolize this.

According to the given values in the question,

y = 0.54x + 90

Where y represents the cost of renting the car and x represents the number of miles.

The plan is to drive 268 miles, so the cost according to that will be :

y = 0.54(268) + 90

y = 234.72 or,

y = 235.

Hence, the round-off cost will be 235 dollars.

The greatest common factor of 24,40 and 72 is 8, which is correctly found by Brenden.

Given the numbers for which the GCF is to be found are:

24,40 and 72.

first take out the least common factors of the numbers:

24 = 2×2×2×3

40 = 2×2×2×5

72 = 2×2×2×3×3

When two or more numbers are supplied, the GCF (Greatest Common Factor) is the sum of all the common factors, which is the largest number. The greatest integer that can divide both x and y evenly and leave no leftover is the GCF of two natural numbers, x and y. Division, multiplication, and prime factorization are the three common methods used to determine GCF.

so the GCF is 2×2×2 = 8

we should choose Brendon.

Hence the correct GCF is 8, computed by Brendan.

Answer:54.98783

Step-by-step explanation:

1 times a number is just the number itself.

So if you let x and y be the two numbers...

the sum of the two means you add them together... so you get:

x+y=56: the difference means you subtract them.. so

x-y = 16

now you have two equations and two unknowns... which you can solve with various methods... you can use elimination, substitution, or trial and error.

x+y=56

x-y = 16

I will use the elimination method: Because there is a plus y and a negative you cancel that out and add the 2x's. Therefore:

2x=72

x=36

Now, you can plug 36 into one of your original equations:

36+y=56

y=20

Those are your two numbers!

The rectangle's area varies by 4%.

What is the area?

The area of a rectangle in such a two-dimensional plane is the area that it occupies.

It has length and breadth.

A quadrilateral, a form of a two-dimensional object with four sides plus four vertices, is what a rectangle is. The rectangle's four angles are all right angles or exactly 90 degrees.

Length will be 20% longer with an increase, or 120%, or 1.2.

The breadth will indeed be 80% = 0.8 after being reduced by 20%.

Rectangle's area is equal to 1.2 x 0.8, or 0.96, or 96%.

The value of cos I as a fraction in simplest terms is 4/5.

This is a problem based on trigonometry. Trigonometry is a field of mathematics that explores the connections between triangle side lengths and angles. The length of the hypotenuse is 25. The length of the perpendicular is 15. The length of the base is unknown. We know that the angle ∠IJK = 90°.

We need to find the value of Cos(I). But we don't know the value of the length of the base of the triangle. So, we will first find Sin(I).

Sin(I) = 15/25

Sin(I) = 3/5

We know the trigonometric identity that Sin²θ + Cos²θ = 1.

Sin²I + Cos²I = 1

Cos²I = 1 - Sin²I

Cos²I = 1 - (3/5)²

Cos²I = 1 - (9/25)

Cos²I = (25 - 9)/25

Cos²I = 16/25

Cos(I) = √(16/25)

Cos(I) = 4/5

we know that

the coordinates of point B ( -5,0)

the translation has the following rule

(-5,0)-----> (-5+5,0-2)-----> (0,-2)

coordinates is defined as a pair of numbers that describes the exact location of a point on a rectangular plane using horizontal and vertical lines called coordinates. In general, (x, y) represents the x and y value of a point on a graph. Each point or ordered pair contains two coordinates.

the x-coordinate is called the abscissa and the y-coordinate is called the order. Both coordinates (x, y) represent a point on the plane.

Inequalities are connections between non-equal expressions. Inequalities utilize <, >, and. reads "7 is bigger than" (or "is less than 7," right to left).

If we define x as the number of miles she can bike, the minimum is 12 miles, hence x may be more than 12 miles.

12 mi ≤ x

Since her maximum ride is 15 miles, x might be less than or equal to 15 miles:

It is equivalent.

to make a perpendicular function from another we must take its slope and make two transformations

the slope of y=1/3x is 1/3

the transformations:

1.

reverse the number

2.

and change the sign

ok we have the slope now need the general equation of the line

where m is the slope , b a cut point and (x,y) a point

so, we have the slope=-3 , and the point (2,-3) we can replace to find b

now we can replace b and the slope to have the final equation

In order to find the quotient and remainder of the division, let's divide the polynomials doing the following steps:

x³ divided by x: x².

x² times (x + 2): x³ + 2x²

x³ + 6x² + 17x + 11 minus (x³ + 2x²): 4x² + 17x + 11

4x² divided by x: 4x

4x times (x + 2): 4x² + 8x

4x² + 17x + 11 minus (4x² + 8x): 9x + 11

9x divided by x: 9

9 times (x + 2): 9x + 18

9x + 11 minus (9x + 18): -7

Therefore the quotient is x² + 4x + 9 and the remainder is -7
