Given:

The growth of a sample of bacteria can be modeled by the function

b(t)=100(1.06)^t

where, b is the number of bacteria and t is time in hours.

To find:

The number of total bacteria after 3 hours.

Solution:

We have,

b(t)=100(1.06)^t

Here, b(t) number of total bacteria after t hours.

Substitute t=3 in the given function, to find the number of total bacteria after 3 hours.

b(t)=100(1.06)^3

b(t)=100(1.191016)

b(t)=119.1016


Therefore, the number of total bacteria after 3 hours is 119.1016.

If 35.4067=3/p+5/q+4r+6/s+7t, then the value of 2p+4q+5r+7s+3t​
sweet [91]

Answer:

7004.7003

Step-by-step explanation:

We are given the following information in the question:

35.4067=\displaystyle\frac{3}{p}+\frac{5}{q}+4r+\frac{6}{s}+7t

We know that,

35.4067 = (3\times 10^1) + (5\times 10^0) + (4\times 10^{-1})+(0\times 10^{-2}) + (6\times 10^{-3}) + (7\times 10^{-4})

Comparing the two equations, we get:

\displaystyle\frac{1}{p} = 10^1\\\\p = 10^{-1}\\q = 10^0\\r = 10^{-1}\\s = 10^3\\t = 10^{-4}

We have to evaluate:

2p+4q+5r+7s+3t

Putting values, we get:

(2\times 10^{-1}) + (4\times 10^0) + (5\times 10^{-1}) + (7\times 10^3) + (3\times 10^{-4})\\=0.2 + 4 + 0.5 + 7000 + 0.0003\\=7004.7003
