Answer:
1.Unless otherwise specified, a positive rotation is counterclockwise, and a negative rotation is clockwise.
2.The notation used for rotations on the coordinate plane is: Rnumber of degrees(x,y)→(x′,y′).
3.To rotate a shape, you should usually rotate each vertex of the image individually.
Step-by-step explanation:
According to the given sine function, it is found that the period of rotation is of 0.21 seconds.
<h3>What is the period of a sine function?</h3>
Suppose a sine function modeled by:
The period is given by:
.
In this problem, the function is:
h(t)=60+45 sin (30t).
The vertical shift and the amplitude do not interfer in the period, hence B = 30 and:
The period of rotation is of 0.21 seconds.

Justice has 2k cups of water and she gives away 10 to her best friend jaheem what eqaution will that make and how will i solve it an how much does justice have left
Answer:
2/5
Step-by-step explanation:
First, add them all together:
4+1+5 = 10
We know that there are four red balls, so 4 out of ten balls are red, or 4/10 of the total balls. We can simplify from here.
4/10 = 2/5.
Therefore, she has a 40% chance of choosing a red ball.
