<h2>FIND THE VOLUME </h2>

<h3>GIVEN </h3>
  • 10yd
  • 5yd
  • 6yd

<h3>FORMULA</h3>

V =  \frac{1}{3}  (\frac{1}{2}\times base \: area) \:  \times height

<h3>SOLUTION</h3>

V =  \frac{1}{3}  ( \frac{1}{2}\times base \: area) \:  \times height \\ V =  \frac{1}{3} (\frac{1}{2} (6)(5))(10) \\ V =  \frac{1}{3} (150) \\ V = 50 {yd}^{3}

<h2>FINAL ANSWER</h2>

D. \:  \: V = 50 \:  {yd}^{3}

If 3,000 bacteria, with a growth constant (k) of 2.8 per hour, are present at the beginning of an experiment, in how many hours
Ivenika [448]

Given:

Initial number of bacteria = 3000

With a growth constant (k) of 2.8 per hour.

To find:

The number of hours it will take to be 15,000 bacteria.

Solution:

Let P(t) be the number of bacteria after t number of hours.

The exponential growth model (continuously) is:

P(t)=P_0e^{kt}

Where, P_0 is the initial value, k is the growth constant and t is the number of years.

Putting P(t)=15000,P_0=3000, k=2.8 in the above formula, we get

15000=3000e^{2.8t}

\dfrac{15000}{3000}=e^{2.8t}

5=e^{2.8t}

Taking ln on both sides, we get

\ln 5=\ln e^{2.8t}

1.609438=2.8t                  [\because \ln e^x=x]

\dfrac{1.609438}{2.8}=t

0.574799=t

t\approx 0.575

Therefore, the number of bacteria will be 15,000 after 0.575 hours.
