A biologist who has been studying herd movements in elephants just finished spending several hours with the herd. The elephants are now moving due east at 3 kilometers per hour. The biologist, meanwhile, is driving due west to base camp at a rate of at 49 kilometers per hour. In how long will the biologist be 3 kilometers from the herd?

And explain how you got it so i can understand future problems : 3

The frequency table shows the results of a survey comparing the number of beach towels sold for full price and at a discount during each of the three summer months. the store owner converts the frequency table to a conditional relative frequency table by row. which value should he use for x? round to the nearest hundredth. 0.89 0.90 0.92 0.96

The input to the function is x and the output is y. write the function such that x can be a vector (use element-by-element operations). a) use the function to calculate y(-1.5) and y(5). b) use the function to make a plot of the function y(x) for -2 ≤ x ≤ 6.
