Figure ABCD is rotated clockwise about the origin through 90°. Identify the coordinates for the given figure after 90° rotation
nydimaria [60]

Answer:

D[3, 3], C[1, 4], B[0, 1], A[4, -1]

Step-by-step explanation:

Whenever you are doing a 90° clockwise rotation ABOUT THE ORIGIN, it is in the form of [<em>y</em><em>,</em><em> </em><em>-</em><em>x</em>], meaning you take the <em>y</em><em> </em>and make it your <em>x</em><em>,</em><em> </em>then take your original <em>x</em><em> </em>and put its OPPOSITE.

90° counterclockwise rotation → [<em>-y, x</em>]

90° clockwise rotation → [<em>y, -x</em>]

I hope this helps, and as always, I am joyous to assist anyone at any time.

The key values are called a five-number summary, which consists of the minimum, first quartile, the set is put into increasing order, divides the data into two equal parts. First, we put the values in the data set into increasing order: 3, 5, 7, 8, 12, 13, the middle score for a set of data that has been arranged in order from least to greatest. A box-and-whisker plot shows the distribution of a set of data along with... Quartiles are values that divide a set of data into four equal parts. The second Quartile ( designated Q2) also called the median or the 50th percentile (cuts data set in half ).

Complete this conversion. given: 10 mm = 1 cm given: 100 cm = 1 m find: 7.5 m = ___ mm
krek1111 [17]
We have that
10 mm is equal to -------> 1 cm----> multiply by 100
10*100 mm is equal to -------> 1*100 cm
1000 mm is equal to -------> 100 cm
and
we know that
100 cm is equal to-------> 1 m
therefore
1000 mm is equal to -------> 100 cm
100 cm is equal to-------> 1 m

1000 mm is equal to--------> 1 m
  X mm-----------------> 7.5 m
x-7.5*1000-----> x=7500 mm

the answer is
7500 mm
