The temperature, T, in °C, of a potato put into an oven is given as a function of time, t, in minutes, by T = a(1 − e−kt) + b. (a) Knowing that the temperature of the potato is initially 20°C tells us that T '(0) = 20 T '(20) = 0 T(20) = 0 T(0) = 20 Knowing that the temperature of the oven is a constant 300°C tells us that lim t→∞ T(t) = 20 lim t→∞ T(t) = 300 lim t→∞ T(t) = ∞ lim t→0 T(t) = 300 (b) Use the information in part (a) to find the exact values of a and b. a = b = 20 (c) Knowing that the temperature of the potato is initially increasing 4°C per minute tells us that

Show a B+ tree that result from inserting the following values 5, 20, 2, 8, 3, 7, 14. Initially the tree is empty and has P = 3. Please use left hand bias. You can draw this on paper and upload a screenshot here. As a reminder for left hand bias: If the node contains the values 4,10 and you insert 7. This results in the over flow 4,7,10 and a new node would be created with 4,7 in one and 10 in the other.

A centrifugal pump discharged 20 liters/sec against a head of 17 m when the speed is 1,500 rpm. The diameter of the impeller was 30 cm and the brake power was 6 hp. A geometrically similar pump with the same impeller diameter is to run at 1,750 rpm. Assuming equal efficiencies, what brake power is required?
