- The population P (in millions) of Texas from 2001 through 2014 can be approximated by the model P=20.913e0.0184t, where t represents the year, with t=1 corresponding to 2001. According to this model, when will the population reach 32 million?arrow_forwardThe number N of beavers in a given area after x years can be approximated by N=5.5100.23x,0x10. Use the model to approximate how many years it will take for the beaver population to reach 78.arrow_forwardChange the function y=3(0.5)x to one having e as the base.arrow_forward
- Repeat the previous exercise to find the formula forthe APY of an account that compounds daily. Usethe results from this and the previous exercise todevelop a function I(n)for the APY of any accountthat compounds n times per year.arrow_forwardPls help ASAParrow_forwardSuppose that 40 deer are introduced in a protected area. The population of the herd P can be modeled by P = 40 + 20x / 1 + .05x where x is the time in years since introducing the deer. Determine the time required for the deer population to reach 200.arrow_forward
- Find the interval where the function, 3 f(x) = - 4x – 2x² is increasing? 21 O a. (-2,-1) O b. (-∞, –1) O c.(-1, 0) O d. Nonearrow_forwardWrite each answer as an equality, and any decimals up to 7 decimal places. Clearly state the value of and δ (or M or N and δ) in each case. (a)How close to 0 do we need to take x so that (x^2 + 6x + 9) < 9.001 ? (b)How close to −7 do we need to take x so that 1/(x+7)^4 > 10000 ?arrow_forwardFind the interval where the function, f(x) = Vax - – 2V3x + 57 is increasing? O a. (5, 6) O b. (-∞0, 5) c. None d.
