Three different hoses, each with its own pump, can be used to fill a swimming pool. if hose a is used by itself, the pool takes 6 h to fill. is hose b is used by itself, the pool takes 3 h to fill. if hose c is used by itself, the pool takes 2 h to fill. if all three hoses are used at the same time, how long does the pool take to fill?

The number of members f(x) in a local swimming club increased by 30% every year over a period of x years. the function below shows the relationship between f(x) and x: f(x) = 10(1.3)xwhich of the following graphs best represents the function? graph of f of x equals 1.3 multiplied by 10 to the power of x graph of exponential function going up from left to right in quadrant 1 through the point 0, 0 and continuing towards infinity graph of f of x equals 10 multiplied by 1.3 to the power of x graph of f of x equals 1.3 to the power of x
