The equation s = v30fd can be used to find a car's speed s in miles
per hour given the length d in feet of a skid mark and the friction
factor f of the road. police measured a skid mark of 90 feet on a dry
concrete road. if the speed limit is 35 mph, was the car speeding?
explain. table below
road | concrete | tar
wet. | 0.4. | 0.5|
dry. | 0.8. | 1.9. |

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
