Answer:
- b. y = 20.077 sin(0.500x - 1.959) + 67.577
Step-by-step explanation:
<u>The easiest way to solve</u>
- 1. Plot the points for one year
- 2. Add the functions to same graph and compare
This gave us the option B as the best fit line
<em>See the graph below</em>
percent discount = (discount)/ original * 100
= (20)/250 * 100
=.08*100
= 8 percent
He got an 8 percent discount
Answer:
It is the third option. (the one which has a black point at X=1, Y=1)
Step-by-step explanation:
For simplicity what you should do is, you should satisfy the second condition that is, y=0 if x=1.
Here only the third option is satisfying this condition.
Whenever there is is a white circle or a white point it means that the point does not satisfy the condition and the the function is not defined at that point. And the black point means that the circle is defined at that point and satisfies the condition.
Henceforth, the correct answer is the third option.
