Answer:
The original price of the laptop is 840
Step-by-step explanation:
Here, we want to calculate the original price of a laptop, given the amount that was paid off and the discount percentage enjoyed.
Firstly, let’s add back the 50 taken off. That makes a total of 50 + 664 = 714
Now, we remember he was also given 15% off. Let the price paid be x;
The 15% of x is equal the difference between x and the 714
Thus;
15/100 * x = x - 714
15x/100 = (x-714)
15x = 100(x-714)
15x = 100x -71400
100x-15x = 71400
85x = 71400
x = 71400/85
x = 840
Answer:

Step-by-step explanation:
The trigonometric functions have some features like amplitude, period, phase shift, and vertical shift.
Retrieving the original cosecant graph and copying and attaching it below we have this function:

1) Period
Since the period of a basic secant and basic sine function 

2) Vertical Shift
This value affects the graph by displacing it from x-axis.
The Vertical Shift does not need calculation for it is given by the parameter "d"

Yeah i think that’s right im sorry if not
