Answer:Step-by-step explanation:
The sine of 35 degrees = x / 15
x = sine (35) * 15
x = 0.57358 * 15
x = 8.6037
Answer:
.
Step-by-step explanation:
We are given the graph of a sinusoidal function.
From the graph we see that,
The given graph is represented by the function ![f(x)=\sin(3x)](https://tex.z-dn.net/?f=f%28x%29%3D%5Csin%283x%29)
<em>Now, 'If a function f(x) is of period P, then f(bx) has period
'.</em>
So, we get,
As,
have period
.
Then,
have period
i.e.
.
Since, 'Frequency is the reciprocal of the period',
We have,
Frequency of the given function is
.
Answer:60
Step-by-step explanation:20x6=120 120/2=60
Step-by-step explanation:
Graph the parabola using the direction, vertex, focus, and axis of symmetry.
Direction: Opens Up
Vertex: (0,−2)
Focus:
![(0 , - \frac{15}{8})](https://tex.z-dn.net/?f=%20%280%20%2C%20-%20%5Cfrac%7B15%7D%7B8%7D%29)
Axis of Symmetry:
x
=
0
Directrix: y =
![- \frac{17}{8}](https://tex.z-dn.net/?f=%20-%20%20%5Cfrac%7B17%7D%7B8%7D%20)
