A pet store owner has huge aquarium tanks of the same size, A and B. Tank A has 2 feet of water and is filled at a rate of 2.2 inches per minute.
Tank B has 8 feet of water and is filled at a rate of 5 inches per minute.

There is a line with slope 1/a going through the point (a, a²). find the equation of the line perpendicular to this line at this point. (don’t let this problem intimidate you! solve the problem as you would if i’d given you specific values. just use variables instead.)

The actual length of side y is 22 cm. use the scale drawing to find the actual length of side x. a) 15.2 cm b) 17.1 cm c) 18.0 cm d) 28.3 cm
