(1, 3), (2, 5), (3, 7) (4, 9) and (1, 3), (2, 3), (3, 3) (4, 3) are the relations that represent a function.  

A relation is a function if it has only One y-value for each x-value.

The given Relation is (1, 3), (2, 5), (2, 7) (4, 9)

The relation is not a function as 2 is repeated.

The given Relation is (1, 3), (2, 5), (3, 7) (4, 9)

The relation is a function as no number is repeated.

The given Relation is (1, 3), (1, 5), (1, 7) (4, 9)

The relation is not a function as 1 repeated.

The given Relation is (1, 3), (2, 3), (3, 3) (4, 3)

The relation is a function as no number is repeated.

The given Relation is (1, 2), (2, 5), (2, 1) (4, 5)

The relation is not a function as 2 repeated

Hence, (1, 3), (2, 5), (3, 7) (4, 9) and (1, 3), (2, 3), (3, 3) (4, 3) are the relations that represent a function.

Answer:

A). Options (C) and (E)

B). 4.8 times

Step-by-step explanation:

Part A

Volume of cylinder (1) = πr²h

                                    = π(6)²(5)

                                    = 565.5 cubic inches

Volume of cone (1) = [tex]\frac{1}{3}\pi (r)^2h[/tex]

                               = [tex]\frac{1}{3}(\pi )(6)^2(5)[/tex]

                               = 188.5 cubic inches

Volume of cylinder (2) = πr²h

                                     = π(6)²(15)

                                     = 1696.5 cubic inches

Volume of cone (2) = [tex]\frac{1}{3}\pi (r)^2h[/tex]

                                = [tex]\frac{1}{3}\pi (6)^2(15)[/tex]

                                = 565.5 cubic inches

Volume of sphere = [tex]\frac{4}{3}\pi r^{3}[/tex]

                              = [tex]\frac{4}{3}\pi (6)^{3}[/tex]

                              = 904.8 cubic inches

Figure having volume greater than 600 cubic inches are cylinder (2) and sphere.

Options (C) and (E) are the correct options.

Part (B)

[tex]\frac{\text{Volume of sphere}}{\text{Volume of cone (1)}}[/tex] = [tex]\frac{904.8}{188.5}=4.8[/tex]

Therefore, volume of sphere is 4.8 times the volume of cone (1).

Answer:

Step-by-step explanation:

Given parameters:

Time of going out = 12:15pm

Amount spend on two books  = $42.20

Amount spend toys = $5.67

Time of arrival  = 1:00pm

The amount Sarah spent on each of the two books;

      = [tex]\frac{total amount spent on the books }{number of books}[/tex]

Amount spent on each books  = [tex]\frac{42.20}{2}[/tex]   = $21.1 per book

The relevant information to solve this problem are the number of books and the cost of the book.

Answer:

2(y-7) = 3

Step-by-step explanation:

The tables should be filled in the following order:

3d³   11d²   -4d

-18d²   -99d   36

Polynomial, a mathematical expression made comprised of numbers and variables arranged in specific patterns.

As per the given data:

We are given a table where in each row and each column an expression is written, we have to fill the table correspondingly after finding out the product of each row head and column head

For row with d and column with 2d²:

= d × 2d² = 3d³

For row with d and column with 11d:

= d × 11d = 11d²

For row with d and column with -4:

= d × -4 = -4d

For row with -9 and column with 2d²:

= -9 × 2d² = -18d²

For row with -9 and column with 11d:

= -9 × 11d = -99d

For row with -9 and column with -4:

= -9 × -4 = 36

The tables should be filled in the following order:

3d³   11d²   -4d

-18d²   -99d   36

Hence, The table should be filled in the following order:

3d³   11d²   -4d

-18d²   -99d   36

Answer:

After correcting error of Mia and solving the expression[tex]0.38 \times 3 \div(-1/20)\times5\div(-8)[/tex] we get 14.25

Step-by-step explanation:

The given expression is:[tex]0.38 \times 3 \div(-1/20)\times5\div(-8)[/tex]

First I solve the expression, and then will point the error

[tex]0.38 \times 3 \div(-1/20)\times5\div(-8)\\Converting \ \div \ sign \ into \ \times the \ term \ is \ inverted\\=0.38 \times 3 \times(-20)\times5\times(-1/8)\\=0.38\times 3 \times-20\times5\times-1/8\\=1.14 \times-20\times5\times-1/8\\=-22.8\times5\times-1/8\\=-114\times-1/8\\=\frac{-114}{-8}\\=14.25[/tex]

So, the mistake Mia did was when she inverted division sign into multiplication, she didn't invert the term next to division sign.

The step she did was: [tex]0.38 \times 5 \times(1/20)\times3\times(-8)[/tex]

While the correct step was: [tex]0.38 \times 3 \times(-20)\times5\times(-1/8)[/tex]

After correcting error of Mia and solving the expression[tex]0.38 \times 3 \div(-1/20)\times5\div(-8)[/tex] we get 14.25

Answer:

3 (second option)

Step-by-step explanation:

g(x) is a piecewise function. To find g(3), you have to see which condition the number 3 satisfies.

Out of the options provided, the only condition 3 satisfies is x≥3.

The equation provided for x being greater than or equal to 3 is 6 - x.

Now we can plug in our x value of 3 and solve.

g(3)= 6 - 3

g(3)= 3

Answer:

John makes a total of $1,300.

Step-by-step explanation:

We know that before his bonus, John already has $500. Then, he gets $200 every day for 4 days.

200 x 4 = $800

So, over the course of those 4 days, Johnny makes $800. Now, let's add this to the rest of his money.

800 + 500 = $1,300

Therefore, John makes a total of $1,300.

Use the translation formula to determine the new points.

A' → [tex](5 + 4, -8 + 2) = (9, -6)[/tex]

B' → [tex](1 + 4, -1 + 2) = (5, 1)[/tex]

C' → [tex](-7 + 4, -3 + 2) = (-3, -1)[/tex]

A' = (9, -6)

B' = (5, 1)

C' = (-3, -1)

The new coordinates are obtained as  A'(-4, 7), B'(3, 1) and C'(-3, -1) respectively.

The graph of a function can be transformed by either shifting it in the right, left, up or down.

When the transformation is rightwards, the function becomes as f(x - a).

For left shifting it is f(x + a).

And, for up and down shift it is a + f(x) and a - f(x) respectively.

The new coordinates after the transformation is given as follows,

Apply the given transformation (x,y) → (x + 4,y + 2) as below,

The coordinates of A' are (-8 + 4, 5 + 2)  = (-4, 7).

The coordinates of B' are (-1 + 4, -1 + 2)  = (3, 1).

The coordinates of C' are (-7 + 4, -3 + 2)  = (-3, -1).

Hence, the coordinates after the transformation become as A'(-4, 7), B'(3, 1) and C'(-3, -1).
