You can represent the measures of an angle and its complement as x° and (90 − x)°. similarly, you can represent the measures of an angle and its supplement as x° and (180 − x)°. use these expressions to find the measures of the angles described. the measure of an angle increased by 38° is equal to the measure of its complement.

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
