Answer:
is this a triangle or quadrilateral?
ANSWER

EXPLANATION
Let the equation of the sine curve be of the form;

where a=5 is the amplitude and period,

This implies that


We substitute the values we got so far into our equation to obtain;

When we substitute (2,0) we obtain;

Solve for c.




Hence our equation becomes

The correct choice is D.
To find an equation to describe the relationship between t and c you:
1. Find what is the dependent variable and the independent variable
In this case the total cost of the tickets depend of the number of tickets. Then:
Dependent variable is C
Independent variable is T
-----------------------------------------------------------
You can see in the table that the difference between the cost of the tickects is 165 for every 3 tickets. you find this by substracting the data in every column, as follow:
Then, the equation will be a lineal equation with a slope of:

You use a point of the lineal relationship to find the equation:
(2,110) t1=2 c1= 110
You use the next formula:

You replace the coordinates of the point and find the value of b:


The equation is:
Answer:
C.
Step-by-step explanation:
Quadrant 1 is positive positive, Quadrant 2 is negative positive, and quadrant 3 is negative negative. Quadrant 4 is positive negative.
