Using the unit circle, determine the value of sin(-240°).

Step-by-step explanation:

Use the slope-intercept form to find the slope and y-intercept.

Slope:

−

3

y-intercept:

(0 , 3)

Any line can be graphed using two points. Select two

x

values, and plug them into the equation to find the corresponding

y

values

Graph the line using the slope and the y-intercept, or the points.

Slope:

−

1

3

y-intercept:

(0 , 3)

Answer:

B.

Step-by-step explanation:

Vertex with (2,4) means that the equation will have:

y=a(x-2)^2 + 4

Open downwards means that the a will be negative:

so: y = -a (x-2)^2 + 4

Stretched by a factor of 3 means that the a=3

So if we combine all of these, we will get the equation:

y = -3 (x-2)^2 + 4

Both ran equal and both covered equal distance.

As cruz ran 1 lap out of 4 to cover one mile.

and erica ran 3 lap out of 12 to cover one mile:

3/12 = 1/4

So Cruz = Erica = 1/4.

Hence Both ran equal.

Step-by-step explanation:

because it doesn't have any value in its first equation

On the number line the position of point F is at point 4.

According to the statement

We have a given that the on a number line , point D is at -3, and point E is at 6. The point F lies on the ratio of to is 2 : 3.

and we have to find the F point on the number line.

Firstly,

Number line is a line on which numbers are marked at intervals, used to illustrate simple numerical operations.

So, According to given information,

Point D is at -3, and point E is at 6.

Ratio of point E to F = 6*2/3

Then

Ratio of point E to F = 6*2/3

After solving it

The point F = 2*2

The point F = 4.

So, On the number line the position of point F is at point 4.

The height of the cylinder is 4 x units.

The area of the cylinder’s base is One-fourthπx2 square units .

What is the volume of cylinder?

We know the volume of a cylinder is given by the formula  π r2 h, where r is the radius of the cylinder and h is the height.

Formula for volume of the cylinder

V = r² π h

Volume of the cylinder= πx³

Diameter=x

Radius (r)=diameter/2

       r  =  x/2

     V = r² π h

   πx³=(x/2)² πh

πx³= (x²/4)πh

Divide both sides by π

x³ =(x²/4)h

Make h the subject of the formula

  h = x³ ÷ x²/4

     =x³ ×4 / x²

     =4x³ / x²

     =4 * x * x * x / x * x

  h=4x

Area of the base:

B = r² π

r=x/2

B=(x/2)² * π

 =(x²/4)π

=πx²/4

=1/4(πx²)

Therefore, The area of the cylinder’s base is One-fourthπx2 square units.

The probability of rolling an even number with six sided equally weighted die is 0.5.

Given a six sided equally weighted die.

We are required to find the probability of rolling an even number.

Probability is the calculation of  likeliness of happening an event among all the events possible. It lies between 0 and 1. It can be calculated  through simple values and with the formula of combination also. The formula of calculating probability is as under:

Probability= number of items/ total number of items.

Total sides in die=6

Total numbers=1,2,3,4,5,6, therefore 6.

Even numbers=2,4,6. Therefore 3.

Probability = even numbers/total numbers.

=3/6

=1/2

=0.5

Hence the probabilty of receiving an even number from a six sided equally weighted die is 0.5.

(b) The city having the highest noon temperature is city B.

(c) The city having the noon temperatures with a higher interquartile range is city A.

(d) The city having more noon temperatures that 81°F is city B.

In the given question, the noon temperatures for two cities, A and B, recorded over a month are shown via the box-and-whisker plots.

We are asked to use it and answer the questions:

(a) The median of data is represented by the line in the box of the box-and-whisker plot. Thus,

The median noon temperature for city A is 73°F.

The median noon temperature for city B is 76°F.

Thus, the city with a larger median room temperature is city B.

(b) The highest temperature is seen as the end point of the whiskers. Thus,

The highest temperature for city A is 85°F.

The highest temperature for city B is 92°F.

Thus, the city having the highest noon temperature is city B.

(c) The interquartile range is the difference between the end line of the box and its start line. Thus,

The interquartile range for city A is (81 - 64)°F or 17°F.

The interquartile range for city B is (81 - 68)°F or 13°F.

Thus, the city having the noon temperatures with a higher interquartile range is city A.

The cross-section of a right rectangular pyramid will be shaped similar to the base, that is, a rectangle. Hence, 4th option is the right choice.

If the peak of the rectangular pyramid is directly above the center of the base, it creates a perpendicular to the base, indicating the height of the pyramid. This type of rectangular pyramid is known as the right rectangular pyramid.

A rectangle is a quadrilateral, that is a closed figure with 4 line segments, with all four interior angles at 90°.

When we slice a right rectangular pyramid vertically down at the red line by a plane, not passing through the vertex, of the pyramid will be a dilated image of its base.

A dilated image is an enlarged or diminished image of the preimage, similar with all angles.

Thus, the cross-section of a right rectangular pyramid will be shaped similar to the base, that is, a rectangle. Hence, 4th option is the right choice.
