Abiologist wants to know the width w of a river in order to properly set instruments for studying the pollutants in the water. from point a, the biologist walks upstream 100 feet and sights to point c. from this sighting, it is determined that θ = 56° (see figure). how wide is the river? verify your result numerically. (round your answer to one decimal place.)

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
