ANSWER

Option B

and

Option D.

EXPLANATION

The graph of the function has an amplitude of 2 and a period of

\frac{2\pi}{3}

Choose all the equation that has an amplitude of 2 and a period of

\frac{2\pi}{3}

These are:

y = 2 \sin3(x -  \frac{2\pi}{3} )

and

y = 2 \sin(3x)

The second and the last options are correct.

erma4kov [3.2K]

The angle of rotation of triangle ABC to A'B'C is 105°

<h3>How to illustrate the information?</h3>

It should be noted that the rotation from ABC to A'B'C is in a clockwise direction.

Point B is also on the x axis and point B' is in the second quadrant.

In this case, the angle that depicts the second quadrant is 105°.

In conclusion, the correct option is D.

The complete question is:

Triangle A’ B’ C’ is the image of A B C under a rotation about the origin, (0,0)

Determine the angle of rotation

Use the box plot to answer the questions. What is the range of Charles’s scores? What is the median of Charles’s scores? What is
vekshin1

Box-plot describes 5 important data of the observations. We get following values for range, median and IQR as:

  • The range of Charles' scores is 20
  • The median of Charles' scores is 90
  • The IQR of Charles' scores is 8

<h3>How does a boxplot shows the  data points?</h3>

A box plot has 5 data description.

  • The leftmost whisker shows the minimum value in the data.
  • The rightmost whisker shows the maximum value in the data.
  • The leftmost line in the box shows the first quartile.
  • The middle line shows the median, also called second quartile.
  • The last line of the box shows the third quartile.

<h3>How to find the interquartile range?</h3>

IQR(inter quartile range)  is the dfference between third and first quartile. (Its the horizontal length of the box)

<h3>What is the range of a data set?</h3>

Range = Maximum value of the data set - Minimum value of the dataset

The missing box plot is attached below for the given problem.

From the given data, we see that, the left and right whiskers are on  80 and 100 respectively.

The left and right limit of the box are on 85 and 93 respectively.

The middle line lies on 90.

Thus, we get:

  • Minimum score = left whisker = 80
  • Maximum score = right whisker = 100
  • First quartile = left limit of box = 85
  • Third quartile = right limit of box = 93
  • Second quartile = median = middle line's position in the box = 90

Thus, we get:

  • Range of Charles' score = Max - min value = 100 = 80 = 20
  • Median of Charles' score =  90
  • IQR = third quartile - first quartile = 93 - 85 = 8

-34 + 52 + -18 (Intergers!!)
enyata [817]
We need to follow PEMDAS

We have to do the addition and subtraction from left to right.

Rearrange the terms

52 - 18 - 34

52 -1(18+34)

52 -1(52)

52 - 52

0



So, at the end, your final answer is 0.
