The growth of bacteria is modeled as P = P0ert. In a sample culture, the bacteria grows at a rate of 6 percent per minute. If th

e initial count in the sample is 1,000, how many bacteria will there be after five minutes? (Consider e = 2.718.)
A) 1,005
B) 1,030
C) 1,350
D) 2,350
E) 20,079

Initial number of Bacteria = Po = 1000
Growth rate = r = 6% = 0.06
We want to find the number of Bacteria after 5 minutes.

Using the given equation, we can write:

P= P_{o}e^{rt} \\  \\ 
P=1000(2.718)^{0.06*5}  \\  \\ 
P=1000(2.718)^{0.3} \\  \\ 
P=1350

Rounding of to nearest integer, the number of Bacteria after 5 minutes will be 1350. So option C gives the correct answer

We might choose to write a recursive formula rather than an explicit formula to define a sequence because (D) the sequence is strictly geometric.

<h3>What is a sequence?</h3>
  • A sequence in mathematics is an enumerated collection of items in which repetitions are permitted and order is important. It, like a set, has members (also called elements, or terms).
  • The length of the series is defined as the number of items (which could be infinite).
  • Unlike a set, the same components can appear numerous times in a sequence at different points, and the order does important.
  • Formally, a sequence can be defined as a function from natural numbers (the sequence's places) to the elements at each point.
  • The concept of a sequence can be expanded to include an indexed family, which is defined as a function from an index set that may or may not contain integers to another set of elements.

Recursive formulas are commonly used to compute the nth term of a sequence, where a(n) is the sum of all the preceding values.

Using its position, explicit formulas can compute a(n).

Therefore, we might choose to write a recursive formula rather than an explicit formula to define a sequence because (D) the sequence is strictly geometric.

d) 8/21

Step-by-step explanation:

total number of coins: 21

a) number if dollars: 5

therefore fraction is 5/21

b) number of quarters: 4

therefore fraction is 4/21

c) number of dimes: 4

therefore fraction is 4/21

d) number of nickels: 8

therefore fraction is 8/21

Please help<br><br>answer choices are:<br><br>A. 46°<br><br>B. 67°<br><br>C. 115°<br><br>D. 134°​
bekas [8.4K]

Answer:

134°

Step-by-step explanation:

∠BAC = ∠BCA because it is an isosceles triangle

∠XCA = ∠XAC .  Congruent angles

∠XAC = 1/2(46) = 23° .  because CE bisects ∠ C

∠XCA = 23°

180° - 23° - 23° = 134° .  Sum of all angles in a triangle is 180°

If my answer is incorrect, pls correct me!

If you like my answer and explanation, mark me as brainliest!
