For the following exercises, use this scenario: A biologist recorded a count of 360 bacteria present in a culture after 5 minutes and 1000 bacteria present after 20 minutes. Rounding to six significant digits, write an exponential equation representing this situation. To the nearest minute, how long did it take the population to double

Answers

Answer:

$P(t)=256*e^(0.068185t)$

10 minutes for the population to double.

Step-by-step explanation:

The general formula for the population equation, P(t), is:

$P(t)=A*e^(nt)$

We are given that for t =5 minutes and t = 2 minutes:

$P(5)=360=A*e^(5n)\nP(20)=1,000=A*e^(20n)\n\n$

Solving for A and n:

$ln(360)=ln(A)+5n\nln(1,000)=ln(A)+20n\nln(1,000)-4ln(360)=ln(A)-4ln(A)+20n-20n\nln(A)=5.5455536\nA=256\nn=(ln(360)-ln(256))/(5)\nn=0.068185$

The exponential equation that represents this situation is:

$P(t)=256*e^(0.068185t)$

The population will double when P(t) = 512 bacteria:

$512=256*e^(0.068185t)\nln(2)=0.068185t\nt=10.17\ minutes$

To the nearest minute, it takes roughly 10 minutes for the population to double.

Andy has two rectangular gardens. His smaller garden is 8 feet long and 4 feet wide. The larger garden is 12 feet long and six feet wide. Which statement correctly describes Andy gardens?a/The gardens are only congruent.
b. The gardens are similar and congruent.
c. The gardens are congruent, but not similar.
d. The gardens are similar, but not congruent.

Answers

The garden are similar, but not congruent option (D) is correct after applying the concept of similarity.

What is the congruent triangle?

Congruent triangles are those that are exactly the same size and shape. Congruent is represented by the symbol ≅ When the three sides and three angles of one triangle match the dimensions of the three sides and three angles of another triangle, they are said to be congruent.

It is given that:

Andy has two rectangular gardens. His smaller garden is 8 feet long and 4 feet wide.

The larger garden is 12 feet long and six feet wide.

As the corresponding dimensions are not same but have in equal ratio or proportions.

Thus, the garden are similar, but not congruent option (D) is correct after applying the concept of the similarity.
