Write the equation of the graph
olchik [2.2K]

Answer:

y = 2.cos(x) - 2

Step-by-step explanation:

1. Shifting cos(x) right or left, top or down, as the graph in the question has the same illustration of  cos(x). Consider

y = a.cos(x) + b

2. find a and b by using two sample points from the graph: (0, 0) and (\pi, -4)

0 = a.cos(0) + b  => a + b = 0\\ -4 = a.cos(\pi) + b => b-a=-4\\\left \{ {{2b=-4} \atop {2a=4}} \right.\\a = 2, b=-2\\

The container that holds the water for the football team is 1/6 full. After pouring in 14 gallons of water, it is 3/4 full. How
Galina-37 [17]

We solve the equation (1/6)x + 14 = (3/4)x, where x is the number of gallons;

We have 2x/12 + 168/12 = 9x/12;

2x + 168 = 9x;

168 = 7x;

x = 168 ÷ 7;

x = 24 gallons;
