Explanation Given: The number of people N (measured in thousands) who participate in boating can be described by the function: N ( x ) = 1.99 x 2 − 6.76 x + 1098.4 where x is the mean income (measured in thousands) and x ≥ 10 . Calculation: Consider the provided inequality, N ( x ) = 1.99 x 2 − 6.76 x + 1098.4 The values of N ( x ) at different x are: N ( 10 ) = 1229.8 N ( 30 ) = 2686.6 N ( 50 ) = 5735.4 And, N ( 70 ) = 10376.2 N ( 90 ) = 16609 So, the coordinates are ( 10 , 1229

Students have asked these similar questions

A researcher wants to determine if the exam scores of the students are dependent on the length of time spent in studying the subject. Ten students in a certain class were taken and the results are shown in the table below where X is the time spent in studying the subject in hours and Y is the examination scores. (Copy-paste the data and run the analysis using MS Excel). X (time) Y (score) 1.5 80 3.0 83 1.25 83 0.5 70 3.5 85 2.5 75 1.0 70 3.0 90 2.5 86 4.0 91 Predict the examination score (rounded to the nearest integer) of a student who spends 2 hours in studying the subject.

The table shows the times it takes a certain model of car to accelerate from 0 mph to speeds of 30 mph, 40 mph, etc., up to 90 mph, in increments of 10 mph. Time (sec) Speed (mph) Time (sec) Speed (mph) 1.7 30 7.9 70 2.8 40 10.3 80 4.1 50 13.0 90 5.7 60 (a) Represent the times by x and the speeds by y. Which function type would be a reasonable choice to model these data? (Multiple Choice) A. power functioncubic function B. linear function C. quadratic function D. Any of these functions would be a reasonable choice. (b) Find the power function model for the data. (Round your coefficients to three decimal places.) y = ? (c) Graph the points and the function to see how well the function fits the points. (d) What does the model indicate the speed (in mph) is 5 seconds after the car starts to move?
