Suppose there are initially 2,200 bacteria in a culture and the number of bacteria triple each hour, the number of bacteria after t hours can be found using the formula y = 2200(3)t. How long will it take the culture to grow to 180,000 bacteria?

simplify: 6x3 - 48x2 + x - 8

a submarine is moving inside the Atlantic ocean according to the formula y1=x2+2x-2. A school of fish is travelling inside the Atlantic ocean according to the formula of y2=- 0.5. scientists have approached you, in order to help them in the following:
1. On the same graph, draw the tracks of both the submarine and the school of fish.
2. Find the roots of the submarine track, by solving the y1 equation.
3. Identify the co-ordinates of intersection between the submarine and the school of fish.
