Step-by-step explanation:

Step 1

recall the eqn of a line y = mx + c

where m is the slope

step 2

compare you eqn given with the eqn y = mx + c

y = mx + c

y = 1 x + 17

then m = 1 which is slope.

Let x be time, in semesters, remaining before Manuel graduates.  We find that Manuel's expenses are:

$1478/semester in tuition, and

$121/semester in fees

1.  x semesters remaining:  fees

  Remaining cost for fees, y, is the product of the fee times the number of semesters, x:

y =($121/semester)*x

y = ($121)*x

2.  x semesters remaining:  tuition

-1                   -2

0                   -0

1                    -2

2                   -8

Also, a graph of the solution of this quadratic equation is shown in the image attached below.

In Mathematics, the valid and true solutions to the given quadratic equation (y = -2x²) are referred to as ordered pairs and they can be determined by substituting the x-values contained in the table into the quadratic equation as follows;

When x = -2, the y-value for this quadratic equation is given by:

y = -2x²

y = -2(-2)²

y = -2 × 4

y = -8

When x = -1, the y-value for this quadratic equation is given by:

y = -2x²

y = -2(-1)²

y = -2 × 1

y = -2

When x = 0, the y-value for this quadratic equation is given by:

y = -2x²

y = -2(0)²

y = -2 × 0

y = 0

When x = 1, the y-value for this quadratic equation is given by:

y = -2x²

y = -2(1)²

y = -2 × 1

y = -2

When x = 2, the y-value for this quadratic equation is given by:

y = -2x²

Step-by-step explanation:

I took the test

The number of bicycles that must be manufactured to minimize the cost of 250 and the minimum cost is $11,500.

In the given question,

The cost C in dollars of manufacturing x bicyles at a production plant is given by the function shown below;

C(x) = 3x^2-1500x+199,000

(a) In the given question we have to find the number of bicyles that must be  manufactured to minimize the cost.

The given function is

C(x) = 3x^2-1500x+199,000

To find the maximum or minimum value we firstly find the value of f'(x).

C'(x) = 6x-1500

Now put f'(x)=0

6x-1500=0

Add 1500 on both side, we get

6x=1500

Divide by 6 on both side we get

x=250

Hence, the number of bicycles that must be manufactured to minimize the cost of 250.

(b) Now finding the value of function at x=250

C(250) = 3(250)^2-1500*250+199,000

C(250) = 3*62,500-375,000+199,000

C(250) = 187,500-375,000+199,000

C(250) = 11,500

The minimum cost is $11,500.

A graph can be defined as a visual representation or a diagram that represents data or values.

The function is given in the represented graph of g(x)

We have to determine the value of h(0) of the given function in the graph

According to the given graph, we can see that when the value of variable x is 0 and the value of variable y is 5, the domain of the provided function h(x) is 5. This implies that h(0) = 5.

The probability that the vertical faces have the same color painted is 0.6875

There are 6 faces on a cube.

Each face of the cube will either be red or blue.

The probability that one face will have red color = probability that the face will have blue color = 1/2

It is given that the cube is placed on a horizontal surface and the 4 vertical faces have the same color.

The painting of the faces of the cube clearly follows a binomial distribution.

Therefore the probability to color the faces of a cube

= P(4 faces are red, 2 faces blue) + P(4 faces are blue, 2 faces red) + P(5 faces blue) + P(5 faces red) + P(All faces blue) + P(all faces red)

For any binomial distribution

ⁿCₓ X pˣ (1 - p)ⁿ⁻ˣ

where

n = no. of sample

x = random variable

p = probability of success

Hence we get

⁶C₄ X 0.5⁴ 0.5²   + ⁶C₄ X 0.5⁴ 0.5²   +    ⁶C₅ X 0.5⁵ 0.5    +   ⁶C₅ X 0.5⁵ 0.5

⁶C₆ X 0.5⁶    +    ⁶C₆ X 0.5⁶

Using the concept of linear equation in one variable, it is concluded that the total number of students who will go on the trip are 40.

An equation that contains only one variable and has its degree one is called a linear equation in one variable. The general form of linear equation in one variable is ax + b = 0, where a and b are real numbers and a ≠ 0.

Given that food and lodging charge per student = $ 60

Charge per student for bus = $ 40

And the amount paid for the cleaning fee for the bus = $ 30

Let the total number of students who are going on the trip = x

Now, the Total charge for food and lodging = $60x

The total charge for bus fare = $ 40x

Given that total cost paid = $ 4030

Hence, $60x + $40x + $30 = $4030

$100X = $4030 - $30

$100X = $4000

x = 40

Hence, the total number of students who will go on a trip is 40.

From a set of whole numbers less than 25, the probability of getting a number either divisible by 5 or divisible by 3 is 11/25

The set of whole numbers = {0, 1,2,3,4,5.....}

The set of whole numbers less than 25 = {0,1,2,3,4,......,24}

The numbers divisible by 5 = {5, 10, 15, 20}

The numbers divisible by 3 = {3, 6, 9, 12, 15, 18, 21, 24}

The common term is 15

The probability = Number of favorable outcomes /  Total number of outcomes

The number of favorable outcome = 11

Total number of outcomes = 25

Substitute the values in the equation

The probability = 11/25

Hence, from a set of whole numbers less than 25, the probability of getting a number either divisible by 5 or divisible by 3 is 11/25

The motel revenue based on the number of rooms rented and group rental are as follows;

(a) The price for renting three rooms is $195

(b) The formula through which the unit rate of a room is found is aₙ = 71 - 3·(n -1)

(c) The function for the revenue, R(n) = 74·n - 3·n²

(d) The most amount that can be made is $456

The number of rooms that gives the most amount is 12 rooms

A revenue is the total amount received for the sale of goods and services

The number of rooms in the motel = 44

The price for renting one room = $71

The price for renting two rooms = $68

The per room group rate = $71 - $3 for each additional room
(a) The amount made if a family rents three rooms is given as follows;

The unit price for two rooms = $71 - $3 = $68

The unit price for three rooms = $68 - $3 = $65

The price for the three rooms is therefore;

$65 × 3 = $195

(b) The formula that gives the rate charged for each room to an organization is an arithmetic progression, which can be expressed as follows;

aₙ = a₁ + (n - 1)·d

Where;

n = The number of rooms the organization plans to rent

a₁ = The first term of the arithmetic progression = 71

d = The common difference = -3

Which gives;

aₙ = 71 - 3·(n - 1)

The price for each room when an organization rents n rooms is therefore;

aₙ = 71 - 3·(n - 1)

(c) The revenue for renting n room is given by the formula;

Revenue, R(n) = Unit rate × Number of rooms

∴ R(n) = (71 - 3·(n - 1)) × n = 74·n - 3·n²

(d) The -ve coefficient of n² in the formula with which the revenue can be found indicates that the function has a maximum value. The number of rooms that gives the most revenue is obtained at the from the derivative of the R(n) as follows;

R'(n) = 74 - 6·n = 0

n = 74/6 ≈ 12

Which gives;

[tex]R_{max}[/tex] = R(12) = 74 × 12 - 3 × 12² = 456

The maximum revenue from renting to a single group ≈ $456

The number of rooms to rent that gives the maximum revenue is n ≈ 12
