Answer:

Step-by-step explanation:

Arrange the numbers in order from least to greatest;

18, 18, 18, 20, 21, 22, 23, 23, 24, 24

Find the Median = (21+22)/2= 21.5

Find the median (Q1) between 21.5 and 18 = 18

Find the median (Q2) between 21.5 and 24 = 23

How many nanoseconds are in a year?

Answers


       (1 year) x (86,400 sec/day) x (365-1/4 day/yr) x (10⁹ nanos./sec)

  =  (1 x 86,400 x 365-1/4 x 10⁹) nanosec

  =    31,557,600 x 10⁹ nanosec

  =      3.15576 x 10¹⁶ nanosec

(This is a rough answer, because the 'year'
is not exactly  365-1/4 days.)

1 year = 3.1556926 × 10^16 nanoseconds

A triangle with coordinates (6,4), (2, -1), and (-3,5) is translated 4 units left androtated 180° about the origin. What are the coordinates of its image?
A. (2,4),(-2,-1), (-7,5)
B. (4,6),(-1,2), (5, -3)
C. (4,-2),(-1,2), (5,7)
D. (4,2), (-1,-2), (5, -7)

The book has these as the optional answers but I keep getting (-2,-4), (2,1), (7, -5)
Can someone help me??

Answers

Answer: (-2,-4), (2,1) and (7,-5)

Step-by-step explanation:

When rotating a point 180 degrees about the origin a point A(x,y) becomes A'(-x,-y).

When translating a point B(x,y) by 'h' units left, then the new point will become B'(x-h,y).

Given: A triangle with coordinates (6,4), (2, -1), and (-3,5) is translated 4 units left and rotated 180° about the origin.

Translation rule for 4 units left : (x,y) → (x-h,y)

The new coordinates will be (6-4,4) , (2-4,-1) and (-3-4, 5)

i.e. (2,4), (-2,-1) and (-7,5) .

Now, applying the rotation rule of 180 degrees we get the points of the final image as

(-2,-4), (2,1) and (7,-5) .

Hence, the coordinates of its image is (-2,-4), (2,1) and (7,-5) .
