The area A = A(t) and radius r= r(t) are clearly functions of t (they change over time) and are related by the formula A = ar?. Area A = A(t) r = r(t) t, seconds (a) If r is measured in inches and t is measured in seconds, what are the units of ? What are the units dt of dr dA and explain the practical meaning of (b) Find dr dA dr r=2 dA (c) Find and explain the practical meaning of dt dA| dt \r=2arrow_forwardAt time t = 0, Car A passes through an intersection and goes east at a speed of 40 feet per second. Four seconds later, Car B passes through the same intersection and goes north at a speed of 60 feet per second. Find the rate at which the distance between A and B is changing when A is 320 feet from the intersection. Rate = feet per second (Enter an integer.)arrow_forward3. After long study, tree scientists (dendrologists) conclude that a eucalyptus tree will grow at a rate of 0.6 + 4 feet per year, where t is time in (1+1) years. a.

If a person P1 moves with velocity v with respect to an observer P, then a watch carried by P appears to be running more slowly to P2 than to P, by a (dilation) factor of 1 V1 – v²/c² Here c is the velocity of light, approximately 186,000 miles per second. a. If v = c/2, what is the dilation factor? b. If v = c/3600, which is 186,000 miles per hour, %3D estimate the dilation factor. (Hint: Consider the function f (x) = 1/V1 x near 0.)arrow_forward9. A car loses value each year. The value of the car t years from today can be modeled using the 1 function (t) = 15,000(0.85). If Elizabeth wants to sell her car in 2- years, what will the car's %3D 3 value be when she sells it?arrow_forwardNewton's Law of Cooling states that the temperature (7) of an object at any time (1), in minutes, can be described by the equation T= Ts + (To - Ts)e*, where Ts is the temperature of the surrounding environment, To is the initial temperature of the object, and k is the cooling rate. What is the cooling rate of an object if the initial temperature was 400° C, the surrounding environment temperature was 30° C, and it took 105 minutes to cool down to 125° C.

- + I/ MI * 00 Energy consumption in a particular country in quadrillion BTUS can be modeled by C(x) = - 0.014x + 1.295x+ 68,958, where x is the number of years after 1970. a. One solution to the equation 89.258 = - 0.014x+ 1.295x+68.958 is x = 20. What does this mean? b. Graphically verify that x 20 is a solution to 89.258 = - 0.014x+1.295x + 68.958. c. To find when after 2020 the energy consumption in that country will be 89.258 quadrillion BTUS according to the model, is there a need to find the second solution to this equation? Why or why not? a. Choose the correct answer below. O A. In 1990, consumption was 68.958 quadrillion BTUS. O B. In 2020, consumption was 68.958 quadrillion BTUS. O C. In 1990, consumption was 89.258 quadrillion BTUS. O D. In 2020, consumption was 89.258 quadrillion BTUS.
