Answer:

N = 90N_{0} + C

Explanation:

Thinking process:

Let the number of yeast species be N

the rate of doubling be given by the expression: \frac{dN}{dt}

The doubling time = 90 mins

Thus, the rate equation will be: \frac{dN}{dt} = KN

Rearranging gives:

dN = KNdt

Integrating the two sides gives:

\int\limits^a_b {dN} \, = \int\limits^a_b {KN} \, dt

N = KNt + C

or

N= N_{0} t + C

this is the number of yeast at the time t

at t = 0, there are 1.5, and N = C

after t = 90 mins, the number of teaspoons will be:

N = 90N_{0} + C

umka21 [38]

Answer:

$12,650,000.

Explanation:

Reserves is the total amount of a bank's deposit that is not given out as loans

Reserves = Deposits - outstanding loans

Required reserves is the percentage of deposits required of banks to keep as reserves by the central bank

Required reserves = reserve requirement x deposits

0.09 x 415 million = 37.35 million

Excess reserves is the difference between reserves and required reserves

50 million - 37.35 million = 12.65 million
