Mr Adams worked 78 hours during his six-day work week if he worked the same number of hours every day, how many hours did he wor

Vedmedyk [2.9K]

Answer:

Mr Adams worked for 52 hours in four days.

Step-by-step explanation:

To get 52, you divide 78 and 6 and get 13. 13 is how many hours he worked a day. Since we need to find out how many hours he worked for 4 days, we add 13 4 times. If we add, the equation would look like this: 13+13+13+13=52. We can multiply also since it's easier. If we multiply our equation would be 13×4. Therefore, Mr Adams worked 52 hours in four days. Hope this helped

Answer:

(a)Yes, it is an exponential function.

(b) $P(t)=200\cdot 2^{t/20}$

Step-by-step explanation:

(a)A population grows exponentially if it increases by a common ratio(called the growth ratio). We can see from the given information that the population of E.coli doubles every 20 minutes, therefore it is an exponential growth with a growth ratio of 2.

(b)The population, P(t) at any time t of an initial population, $P_o$ with a growth ratio of r over a period k can be modeled using the function:
