I couldn't find a graph with the shape, so I had to use points, sorry.

To reflect a shape, reverse its direction up or down and put it on the same points, positive or negative, accordingly. Reflections usually represent a function.

The volume of cup A is 1570.8 cm³ while the volume of cup B is 6283 cm³

Volume is the amount of space occupied by a three dimensional object or figure.

The cup has the shape of a cylinder, the volume is:

Volume = π * radius² * height

For cup A:

Volume = π * (10/2)² * 20 = 1570.8 cm³

Let each punch be 1 cm³, the number of cups needed = 1570.8 cm³ / 1 cm³ = 1571

For cup B:

Volume = π * (20/2)² * 20 = 6283 cm³

Let each punch be 1 cm³, the number of cups needed = 6283 cm³ / 1 cm³ = 6283

The volume of cup A is 1570.8 cm³ while the volume of cup B is 6283 cm³

Step-by-step explanation:

Considering the given angle and the given formula, it is found that the percentage error for an angle of 0.02 radians is of 0.0067%.

For an angle [tex]\theta[/tex], it is given by the following formula:

[tex]P = 100\frac{|\sin{\theta} - \theta|}{\sin{\theta}}[/tex]

In this problem, the angle is of [tex]\theta = 0.02[/tex], hence:

[tex]P = 100\frac{|\sin{0.02} - 0.02|}{\sin{0.02}}[/tex]

[tex]P = 0.0067[/tex]

The percentage error for an angle of 0.02 radians is of 0.0067%.

Answer:

-21

Step-by-step explanation:

Each of those lines is -3
If you look at the -10, it goes down 2 lines and goes to -16 meaning that if it only went down one line it would only go to -13

Showing that each line is worth -3

It goes down 2 lines from -16 (-6)

so if you go down 6 from -16 that would get you to -21

The answer is: -18

That is because, on the number line, they already have 2 numbers. They are -10 to -16. To go from -10 to -16, you subtract 2. Since the mark is the same distance away as -10 to -16 on this number line, you would subtract  2 from -16, which would be -18.

Answer:

D. 6

Step-by-step explanation:

As the two base angles are equal, this implies that this is an isosceles triangle.  This means that the sides opposite the base angles are also equal.

Therefore, AB = BC

⇒ 3x = 4x - 2

⇒ x = 2

If x = 2, then AB = 3 · 2 = 6

The answer will be the blue line. The y intercept is 1. The slope is -2/3.

Finding the radius of the cylindrical water tank:

[tex]\rightarrow Diameter = 2(Radius)[/tex]

[tex]\rightarrow Radius = \frac{Diameter}{2} = \frac{12}{2} = 6 \ feet[/tex]

Now, let's find the volume of the cylinder by substituting the radius.

In the construction of the tangent to the triangle, the part that needs revision is D. Vance should have constructed all three altitudes instead of only constructing two altitudes.

It should be noted that a triangle simply means a polygon that's has three sides. Also, a triangle has there's edges as well as vertices.

In this case, in order to construct a circle tangent to all three sides of the acute, scalene triangle LMN, it should be noted that the three altitudes have to be taken into consideration.

This wasn't the case in the step given by Vance has only two altitudes were considered. Therefore, this should be the change that is required.

Answer:

x = 123.6°

Step-by-step explanation:

Subdivide the trapezium into a rectangle and triangle.

The triangle is a right triangle with hypotenuse CD and height 12.5cm.

The base of the triangle is 24.3 - 16 = 8.3 cm

To find angle D, use the tan trig ratio:

[tex]tan(\theta)=\dfrac{O}{A}[/tex]  where [tex]\theta[/tex] is the angle, O is the side opposite the angle A is the side adjacent the angle.

Therefore, for the right triangle:

[tex]\tan(\theta)=\dfrac{12.5}{8.3} \implies \theta=56.41583952... \textdegree[/tex]

In a quadrilateral, the sum of the angles between the parallel lines is 180°.  Therefore, m∠C + m∠D = 180°

⇒ x + 56.41573952... = 180

⇒ x = 180 - 56.41573952...

⇒ x = 123.6° (1 dp)

Alternatively, calculate angle C of the right triangle and add it to 90° to find x.

Answer:

Step-by-step explanation:

Use the formula for area of a circle

A = [tex]\pi r^{2}[/tex]

The diameter is 8ft, if there was only a line from the middle to the edge of the circle, then it would be radius

The radius is half the diameter so divide 8 by two and you get the radius

Plug in the radius into the formula

A = [tex](4ft)^{2} \pi[/tex]

the parenthesis indicate you aren't only squaring the ft, but also the 4

4ft * 4ft = 16[tex]ft^{2}[/tex]

(remember you are also multiplying the unit, in this case feet)

A = [tex]16ft^{2} \pi[/tex]

there aren't parenthesis here, meaning you aren't squaring the 16

A = 50.24[tex]ft^{2}[/tex]
