Answer:
F=3
Step-by-step explanation:
Due to the difficulty of visualizing the graph of the function in degrees (graph 1), we will graph it in radians (graph 2)
f(x)=−sin(3x)−1 ≡ y=−sin(3x)−1
To graph y=−sin(3x)−1
y=a.sin(bx+c)+d, where
a=-1, b=3, c=0, d=-1 and the period (T) of the function is:
On the graph 2 we place the original function y=sin(x) to compare
We watch that y=−sin(3x)−1 moves 1 down (-), but amplitud is the same (1)
Frequency is the number of repetitions (3x) of a function in a given interval, so
F=3
Divide 331 by 4.5
331/4.5= 73.555555555555 so you can round to 73.6 mph
Answer:
sure
Step-by-step explanation:
she multiplied it 3 times, so, i dont think 8 should be negative.
Answer:
The length of the other piece is 38 inch.
Step-by-step explanation:
Given:
A 190 inch pipe is cut into 2 pieces. One piece is 4 times the length of the other.
Now, to find the length of the other piece.
Let the length of the other piece be 
.
And the length of one piece be 
.
The total length of the pipe = 
According to question:
⇒
<em>Dividing both sides by 5 we get:</em>
⇒
Therefore, the length of the other piece is 38 inch.
