Use a calculator with a y x key or a ∧ key to solve Exercises 65-70. The 1986 explosion at the Chernobyl nuclear power plain in the former Soviet Union sent about 1000 kilograms of radioactive cesium-137 into the atmosphere. The function f ( x ) = 1000 ( 0 ⋅ 5 ) r 30 describes the amount, F ( x ), in kilograms, of cesium-137 remaining in Chernobyl x years after 1986. If even 100 kilograms of cesium-137 remain in Chernobyl’s atmosphere, the area is considered unsafe for human habitation. Find f (80) and determine if Chernobyl will be safe for human habitation by 2066.

Car A starts from rest at t = 0 and travels along a straight road with a constant acceleration of 6 ft/s^2 until it reaches a speed of 60ft/s. Afterwards it maintains the speed. Also, when t = 0, car B located 6000 ft down the road is traveling towards A at a constant speed of 80 ft/s. Determine the distance traveled by Car A when they pass each other.Write the solution using pen and draw the graph if needed.
The velocity of a particle moves along the x-axis and is given by the equation ds/dt = 40 - 3t^2 m/s. Calculate the acceleration at time t=2 s and t=4 s. Calculate also the total displacement at the given interval. Assume at t=0 s=5m.Write the solution using pen and draw the graph if needed.
