Answer:

The population of bacteria can be expressed as a function of number of days.

Population = \[5*2^{n-1}\] where n is the number of days since the beginning.

Step-by-step explanation:

Number of bacteria on the first day=\[5 * 2^{0} = 5\]

Number of bacteria on the second day = \[5 * 2^{1} = 10\]

Number of bacteria on the third day = \[5*2^{2} = 20\]

Number of bacteria on the fourth day = \[5*2^{3} = 40\]

As we can see , the number of bacteria on any given day is a function of the number of days n.

This expression can be expressed generally as \[5*2^{n-1}\] where n is the number of days since the beginning.

The winner of a 200 mile race drove his car to victory at a rate of 140.2159 mph. What was his time​ (to the nearest thousandth
Keith_Richards [23]

Answer: 1.43 h

Step-by-step explanation:

Velocity is V is defined as the change in position (displacement) d of an object in a specific time t:

V=\frac{d}{t}

Where:

V=140.2159 mi/h is the car's velocity

d=200 mi is the distance the winner car traveled

t is the time

Isolating t:

t=\frac{d}{V}

Solving with the given information:

t=\frac{200 mi}{140.2159 mi/h}

t=1.426 h \approx 1.43 h This is the winner's time

6810 bottles produced last month (of all three kinds)
1/3 of the 6810 were orange = 2270 are the oranges so 6810-2270 = 4540 (both limes and apples)
apples = 3 * limes
apples count is N
limes count is n
N=3n
N+n=4540
3n+n=4540
4n=4540
n=1135 (limes)
N= 3n = 3405 (apples)
