Answer:
(- 4, - 2 )
Step-by-step explanation:
Under a rotation about the origin of 90°
a point (x, y ) → (- y, x ) , then
(- 2, 4 ) → (- 4, - 2 )
Answer:
52.9°
Step-by-step explanation:
step 1
we know that
The total number of successful United States space launches that happened in the years 1957-1995 is equal to
step 2
The numbers of successful United States space launches that happened in the years 1980-1989 is equal to
step 3
The percentage of successful United States space launches that happened in the years 1980-1989 is equal to
step 4
Find out the measure of the central angle you would draw in a circle graph to represent the number of successful United States space launches that happened in the years 1980-1989
we know that
In a circle, 360 degrees represent the 100%
so
using proportion
Find out the measure of the central angle by a percentage of 14.68%
Answer:
15
Step-by-step explanation:
-3x = -5-10
-x=-15
therefore, x=15
