Answer:

Yes you are correct

Step-by-step explanation:

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:

The angle between these radii must be 120º.

Step-by-step explanation:

According to Euclidean Geometry, two tangents to a circle are symmetrical to each other and the axis of symmetry passes through the center of the circle and, hence, each tangent is perpendicular to a respective radius. We represent the statement in the diagram included below.

Then, we calculate the angle of the radius with respect to the axis of symmetry by knowing the fact that sum of internal angles within triangle equals 180º. That is to say:

[tex]\theta = 180^{\circ}-90^{\circ}-30^{\circ}[/tex]

[tex]\theta = 60^{\circ}[/tex]

And the angle between these two radii is twice the result.

[tex]\theta' = 2\cdot \theta[/tex]

[tex]\theta' = 120^{\circ}[/tex]

The angle between these radii must be 120º.

Answer:

x = -149/20

General Formulas and Concepts:

Pre-Algebra

Step-by-step explanation:

Step 1: Define equation

2(x + 469/20) = 32

Step 2: Solve for x

Step 3: Check

Plug in x to verify it's a solution.

Here we see that 32 does indeed equal 32. ∴ x = -149/20 is a solution of the equation.

And we have our final answer!

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

In y = kx, k is the constant proportionality that is multiplying by x. In this equation 6 replaces k and is the constant proportionality.

Answer:

x=4.66

tan(25)=x/10

10tan(25)=x

4.66=x

Answer:

Y= x+2 " substituting value of y

Step-by-step explanation:

Y=5x-4y = 5x - 4

or, 5x - 4(x+2) = 5x - 4

or, 5x - 4x+ 8 = 5x-4

or, x +8 = 5x - 4

or, 0= 5x - x - 4-8

or, 0= 4x - 12

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).
