Answer:
Please check attachments
Step-by-step explanation:
Here, we went to sketch points
We can have them through the array, please check
For the 180 degrees counterclockwise rotation, we have that
(x,y) will become (-x,-y)
So E’ is (4,-5)
Kindly note that the first attachment is E while the second is E’
Answer:
8 units
Step-by-step explanation:
Note that 120 degrees represents 1/3 of 360 degrees. The arc described here is thus 1/3 of the circumference of this circle.
Find this circumference and then multiply that result by 1/3:
The formula for the circumference of a circle with radius r is C = 2πr. Here,
(1/3)*(2)(π)(4 units) = 8.38 units, or (to the nearest integer) approx. 8 units.
Hi there!
An easy strategy to compare fractions is to get a common denominator in both. In this case we could come up with the common denominator of 24 by multiplying 2/6 * 4 and 5/8 * 3.
2/6 * 4 and 5/8 * 3 <--- Equation.
8/24 and 15/24 <--- Simplified from step 1.
And now it's easy to compare!
