1) A pizza, heated to a temperature 350 degree Fahrenheit is taken out of an oven and placed in a 75 degree Fahrenheit room at time t= 0 minutes. The temperature of the pizza is changing at a rate of -110e^-0.4t degrees Fahrenheit per minute. To the nearest degree, what is the temperature of the pizza at time t= 5 minutes?

(A) 112 degree Fahrenheit (B) 119 degree Fahrenheit (C) 147 degree Fahrenheit (D) 238 degree Fahrenheit (E) 335 degree Fahrenheit.

2) A particle moves along the x-axis so that any time t > 0, its acceleration is given by a(t) = ln(1+2^t). If the velocity of the particle is 2 at time t = 1 then the velocity of the particle at time t = 2 is

(A) 0.462 (B) 1.609 (C) 2.555 (D) 2.886 (E) 3.346

3) Insects destroyed a crop at the rate of 100e^-0.1t/ 2-e^-3t tons per day, where time t is measured in days. To the nearest ton, how many tons did the insects destroy during the time interval 7<_ t <_ 14?

(A) 125 (B) 100 (C) 88 (D) 50 (E) 12

4) A particle moves along the x-axis so that at any time t >_ 0, its velocity is given by v(t) = cos (2 - t^2). The position of the particle is 3 at time t=0. What is the position of the particle when its velocity is first equal to 0?

(A) 0.411 (B) 1.310 (C) 2.816 (D) 3.091 (E) 3.411.
