The number of bacteria in a colony growing exponentially. At 4 pm yesterday the number of bacteria is 400.And at 6 pm yesterday

Doss [256]

Answer:

10800

Step-by-step explanation:

The number of bacteria in a colony growing exponentially. At 4 pm yesterday the number of bacteria is 400.And at 6 pm yesterday it was 3600. How many bacteria in the colony at 7 pm?

Step-by-step explanation:

B = B₀ Kⁿ

At 4 pm yesterday the number of bacteria is 400

B₀ = 400

n = number of hrs

at 6 pm yesterday it was 3600 => n = 6- 4 = 2 hrs

B₂ = 3600

=> 3600 = 400 * k²

=> k² = 9

=> k = 3

At 7 Pm Yesterday

n = 7-4 = 3

B₃ = 400 * 3³

=> B₃ = 27 * 400

=> B₃ = 10800

bacteria in the colony at 7 pm = 10800

or B₂ = 3600 & n = 7-6 = 1

Then B₃ = 3600 * 3¹ = 10800

And boom here

1. A grand tour of four cities begins at city A and makes successive stops at cities B, C,

vampirchik [111]

Using distance between two points, it is found that the total distance covered on the tour is of 3400 miles.

Given two points $(x_1,y_1)$ and $(x_2,y_2)$ , their distance is given by:

$D = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

In this problem, the formula is used to find the distance covered on each tour, hence:

$d_{AB} = \sqrt{(400 - 0)^2 + (300 - 0)^2} = 500$

$d_{BC} = \sqrt{(-800 - 400)^2 + (800 - 300)^2} = 1300$

$d_{CD} = \sqrt{(-800 - (-800))^2 + (0 - 800)^2} = 800$

$d_{DA} = \sqrt{(0 - (-800))^2 + (0 - 0)^2} = 800$

Then, the total distance is given by the sum of each separate distance, hence:

$d = d_{AB} + d_{BC} + d_{CD} + d_{DA} = 500 + 1300 + 800 + 800 = 3400$

The total distance covered on the tour is of 3400 miles.
