This sine function has the form y = f(x) = a sin (bx + c), where |a| is the amplitude, b is the frequency, and c determines the phase shift.
The period of this sine curve is 2 pi/b, or (in this problem) 2 pi/(1/2).
The phase shift of this curve is -c/b, or -(pi/4)/(1/2). Simplify this.
The amplitude is |-3|, or just 3.
Draw a set of coordinate axes. Draw light horizontal lines through y=3 and y=-3. These are the max and min. values of this sine function.
Plot the phase shift on your x-axis.
Your sine function will begin at (phase shift value, 0) and continue for one period. Add the period to the phase shift value. Draw a sine curve beginning and ending at these two x-values.
I encourage you to share your calculations and to sketch the graph described here. Then I could give you more specific feedback on your work. Good luck!
Answer:
3.75
Step-by-step explanation:
1.25x3=3.75 easy. you just need to times the height by length
4y - 5x = 9
x = 4y + 11
We can substitute this value of x in the first equation:
4y - 5(4y+11) = 9
4y - 20y - 55 = 9
16y = -64
y = -4
x = 4y + 11
x = -16 + 11
x = -5
