- Repeat Example 5 when microphone A receives the sound 4 seconds before microphone B.arrow_forwardThe wind-chill index W is the perceived temperature when the actual temperature is T and the wind speed v,so we can write W=f(T,v). The following table of values is an excerpt from Table 1 in section 14.1.Use the table to find a linear approximation to the wind -chill index function when T is near -15°C and v is near 50km/h .Then estimate the wind -chill index when the temperature is -17°C and the wind speed is 55km/h.arrow_forwardLet F(3)=1, F′(3)=2, H(3)=4, H′(3)=1.arrow_forward
- Find the general solution of the ODE.arrow_forwardThe motion of an object traveling along a straight path is given by s(t) = at² + vot + so, where s(t) is the position relative to the origin at time t. For Exercise, three observed data points are given. Find the values of a, vO, and so. s(1) = -7, s(2) = 12, s(3) = 37arrow_forwardFind the average rate of change of the function over the given intervals. f(x) = 7x° + 7; a) [2,4], b) [-3,3] %3D a) The average rate of change of the function f(x) = 7x° +7 over the interval [2,4] is (Simplify your answer.) b) The average rate of change of the function f(x) = 7x +7 over the interval [-3,3] is. (Simplify your answer.)arrow_forward
- 6:39. Rajiv and Sumant are taking Stat. (Honours) course from different colleges. Rajiv's scoreun the first year is 76, whereas the class average is 68 with a SD of 5. Sumant scored 82 in the first year while class average score was 71 and SD 8. Compare the performances of the two students relative to their classes.arrow_forwardThe function, f(x), in the graph below has f(1) = 1 and f'(1) = = 2. Which of the following are the coordinates of points A and B? A f(x) 1 1.1 Select one: A(1,1) and B(1.1, 1.2) A(1,2) and B(1.1, 1.21) A(1.2,1) and B(1, 2) A(1,1) and B(1.1, 1.21) A(2,1) and B(1.2, 1.1)arrow_forwardA cell site is a site where electronic communications equipment is placed in a cellular network for the use of mobile phones. The numbers y of cell sites from 1985 through 2014 can be modeled by y = 320.110/1+377e-0.257t 320,110 1 + 377e−0.257t where t represents the year, with t = 5 corresponding to 1985. (a) Use the model to find the numbers of cell sites in the years 1998, 2003, and 2006. (Round your answers to the nearest whole number.) 1998 y = cell sites 2003 y = cell sites 2006 y = cell sites (b) Use a graphing utility to graph the function. (c) Use the graph to determine the year in which the number of cell sites reached 280,000. The number of cell sites reached 280,000 in . (d) Confirm your answer to part (c) algebraically. The number of cell sites reached 280,000 in .arrow_forward
