y = -1/3 x + 5 this equation represents the given graph.

How do you plot points on graph ?

Proof :

(0, 5) and ( 15, 0) these are the points where the graph is plotted.

y = -1/3 x + 5

put x= 0 and find y

y = 0 + 5

y = 5

put y = 0 and find x

0 = -1/3 x + 5

-5 = -1/3 x

x = 15

So, now we get the same points i.e, (0, 5) and ( 15, 0) as plotted in the given graph.

Hence, we can say that  y = -1/3 x + 5 this equation represents the given graph.

The conversion of a unary one-to-one relationship, a unary one-to-many relationship, and a unary many-to-many relationship into relational tables have in common the creation of a separate table to represent the relationship.

This table will have a foreign key referencing the primary key of the entity involved in the relationship.

In each case, the entity is represented by a single table with one or more attributes, and the relationship between the entity and itself is represented by one or more columns in that table. The differences between these types of relationships lie in the cardinality of the relationship and how it is represented in the table structure.

For a unary one-to-one relationship, the entity table will have a foreign key column that references itself, which enforces the one-to-one relationship between two instances of the same entity.

For a unary one-to-many relationship, the entity table will have a foreign key column that references itself, but multiple instances of the same entity can reference a single instance of the same entity.

For a unary many-to-many relationship, the entity table will need to be split into two tables, with a third "junction" table linking them together. The junction table will have two foreign key columns, each referencing the primary key of one of the two entity tables, to represent the many-to-many relationship between instances of the same entity.

So, the commonality is that a single entity table is required to represent the entity in each case, with the differences in the relationship cardinality and structure determining how the entity table is designed and linked to itself.

The price of the single shirt is 7.5 dollars.

Megan and Kyler went to the store together to buy school clothes. Megan purchased 4 shirts and 3 pants for $150.00. Kyler purchased 5 shirts and 2 pants for $117.50.

Therefore,

let

x = cost of a shirt

y = cost of a pant

Hence, using equation,

4x + 3y = 150

5x + 2y = 117.50

multiply equation(ii) by 1.5

4x + 3y = 150

7.5x + 3y = 176.25

subtract equation(i) form equation(ii)

3.5x = 26.25

x = 26.25 / 3.5

x = 7.5

Hence,

4(7.5) + 3y = 150

3y = 150 - 30

3y = 120

y = 120 / 3

y = 40

Therefore, the price of the shirt is 7.5 dollars.

Work Shown:

A+B+C = 180 ..... three angles of any triangle add to 180

(2x+10)+(x)+(2x-30) = 180

5x-20 = 180

5x = 180+20 .... adding 20 to both sides

5x = 200

x = 200/5 ... dividing both sides by 5

x = 40

This is the measure of angle B

We can stop here.

If you need to know the values of the other angles, then,

Then note how A+B+C = 90+40+50 = 90+90 = 180 which helps confirm our answer.

Answer:

Approximately 16.67 liters concentration of the 6% solution and approximately 13.33 liters of the 15% solution are required to make 30 liters of a 10% solution.

Step-by-step explanation:

Let's denote the amount of the 6% solution as x liters and the amount of the 15% solution as y liters. We need to find the values of x and y that satisfy the conditions.

Since we want to make 30 liters of a 10% solution, we can set up the following equations:

Equation 1: x + y = 30 (total volume equation)

Equation 2: (0.06x + 0.15y) / 30 = 0.10 (concentration equation)

From Equation 1, we have x = 30 - y. Substituting this into Equation 2, we get:

(0.06(30 - y) + 0.15y) / 30 = 0.10

Simplifying the equation gives:

(1.8 - 0.06y + 0.15y) / 30 = 0.10

1.8 + 0.09y = 3

0.09y = 1.2

y ≈ 13.33

Substituting y back into Equation 1, we find:

x + 13.33 = 30

x ≈ 16.67

Therefore, approximately 16.67 liters of the 6% solution and approximately 13.33 liters of the 15% solution are required to make 30 liters of a 10% solution.

Step-by-step explanation:

In a parallelogram, opposite sides are equal and parallel. Therefore,

QT = PS = 3y ...(1)

PT + TR = PS

y + 2x + 1 = 3x + 9

2x - y = 4 .....(2)

PR = QT = 3y

PR = SQ = 3x + 9 ....(3)

From equations (1) and (3), we can see that:

3y = 3x + 9

y = x + 3

Substitute this value of y in equation (2):

2x - (x + 3) = 4

x = 7

To find the value of y, we can substitute x = 7 in equation (2):

2(7) - y = 4

y = 10

Therefore, x = 7 and y = 10.

The three approximations for \(\sqrt{1.1}\)using the given Taylor polynomials are: p0(x): 1, p1(x): 1.05, p2(x): 1.04875

A Taylor polynomial is a polynomial approximation of a function that is centred at a particular point in calculus. It is created by multiplying the value of a function's derivative calculated at the centre point by a power of the distance from the centre point for each term in the function expansion as a power series. As the degree of the polynomial rises, the Taylor polynomial provides a more precise approximation of the function. Calculus uses it extensively in areas like numerical analysis, optimisation, and approximation theory.

Recall that the Taylor polynomials are used as approximations for a function near a given point, in this case, centered at 0.

1. Using p0(x) = 1:
Since p0(x) = 1 is a constant, it does not depend on x, so the approximation for  \(\sqrt{1.1}\) is simply 1.

2. Using p1(x) = 1 + x/2:
Substitute x = 0.1 (since 1.1 = 1 + 0.1) into p1(x): p1(0.1) = 1 + (0.1)/2 = 1 + 0.05 = 1.05.

3. Using p2(x) = 1 + x/2 - \(x^2\)/8:
Substitute x = 0.1 into p2(x): p2(0.1) = 1 + (0.1)/2 - (0.1)^2/8 = 1 + 0.05 - 0.00125 = 1.04875.

So, the three approximations for  \(\sqrt{1.1}\)  using the given Taylor polynomials are:
1. p0(x): 1
2. p1(x): 1.05
3. p2(x): 1.04875

Step-by-step explanation:

In oblique cylinder the height (altitude) is measured from the opposite base to the base of the cylinder, but it lies outside. We can find the height using Pythagoras theorem.

       h + 7² = 13²

              h²= 169 - 49

              h² = 120

               h = √120

                h = 10.95 units

radius = r = 7 units

\(\boxed{\text{\bf Volume of oblique cylinder = $\bf\pi r^2h$} }\)

Step-by-step explanation:

The average score for the three classes combined is 75.

Given that :

A teacher gave the same test to three history classes: A, B, and C.

The average (arithmetic mean) scores for the three classes were 65, 80, and 77, respectively.

The arithmetic mean or average is the sum of the scores divided by the total number of students in the class.

Since the number of students ratio in each class is given,

Number of students in A = 4k

Number of students in B = 6k

Number of students in C = 5k

Average scores for the three classes combined is :

A = (65 × 4k) + (80 × 6k) + (77 × 5k)/ (4k+5k+6k)

   = (260k + 480k + 385k) / 15k

   = 75
