Let the function f(x) have the form f(x) = Acos(x - C). To produce a graph that matches the one shown below, what must the value of C be ?

point a is the center of this circle.

the ratio of the lengths of (ef/bc) and (ad/ih) is 2: 1.

step-by-step explanation:

the answer is simply just 6n add the two together as they have an n

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually
