Step 2 To estimate the time for the population to reach 50,000, we graph y = 600(4t) and y = 50,000 and estimate the value of t at the intersection point. y 60 000 50 000 40 000 30 000 20 000 10000 t 2 3 4 We see that the two curves intersect at t= - (Round your answer to the nearest tenth.) Therefore, we conclude that the population reaches 50,000 in about hours. Submit Skip (you cannot come...
The temperature at a point (x, y) is T(x,y), measured in degrees Celsius. A bug crawls so that its position after t seconds is given by x = 4 + t, y = 8 where x and y are measured in centimeters. The temperature function satisfies Tx(5, 9) = 2 and Ty(5, 9) = 7. How fast is the temperature rising on the bug's path after 21 seconds? Step 1 We know that the rate of change of the temperature...
If sin x = and sin y = 13,0<x< 2,39 < y < 2., evaluate tan (x + y)
Evaluate the limit, using L'Hôpital's Rule if necessary. x3 lim X-00 9eX/5 Step 1 +3 The limit to be evaluated is lim ** 9ex/5 By direct substitution we have the following. *3 lim x 9ex/5 Thus, the direct substitution results in --Select-- form. Submit Skip (you cannot come back)
