Answer:
(C) 3 feet
Step-by-step explanation:
We have a function of f(x) here. When Sarina throws the ball, it has been 0 seconds since she threw it.
Since x represents the amount of seconds, we can find the height of the ball (f(x)) by substituting x in as 0.
0 squared is 0, 0 minus zero is 0, and 0+3 = 3, so
Meaning that when Sarina threw the ball, it's height was 3 feet.
Hope this helped!
Answer:
Amplitude, in physics, the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. It is equal to one-half the length of the vibration path.
Step-by-step explanation:
Answer:
Therefore,
Step-by-step explanation:
Unit Circle:
In mathematics, a unit circle is a circle with a unit radius. Frequently, especially in trigonometry, the unit circle is the circle of radius one centered at the origin (0, 0) in coordinate System.
So the coordinate of point P on the circle is given as,
Here,
Given:
P(-3,2)
So if Radius is one unit i.e r = 1 then on Comparing we get
∴
Therefore,
C-9<20
c=eleven or anything below
