Answer:
Q = 3.2
Step-by-step explanation:
So basically you would first re-order the equation. 6.4 + Q = 9.6
Then after that you will move all the terms containing Q to the left and the rest of them on the right. After that you will -6.4 to both sides of the equation. Which will look like this.
6.4 + (-6.4) + Q = 9.6 + (-6.4)
Then you will combine the like terms.
6.4 + (-6.4) = 0.0
0.0 + Q = 9.6 + (-6.4)
<u>Q = 3.2</u>
We have been given graph of a sinusoidal function. We are asked to write function formula for our given graph.
We know that and . We can see that our given function is starting at origin, so our graph is sine function.
We know that general form of sine is , where,
A = Amplitude,
Period:
C = Horizontal shift,
D = Vertical shift.
We have been given that function has no horizontal shift, so the value of C is 0.
We can also see that midline of our function is x-axis, so there is no vertical shift as well that is .
We can see that function goes up to 1 from midline and goes down to from midline, so amplitude of function is 1 that is .
We can see that period of our given function is because it completes one cycle from to
We can see that our function is reflected about x-axis, so our function will be .
Therefore, our required function is .
Answers are y = 2 , y = 2.5
Total Units = 4+5+9 = 18
so, 1 unit value = 180/18 = 10
Degrees will be : 4(10), 5(10), 9(10) = 40, 50 , 90
