A strand of bacteria has a doubling time of 15 minutes. If the population starts with 10 organisms, how long would it take for t

slamgirl [31]

In 90 minutes the population to grow to 700 organisms.

Given that,

A strand of bacteria has a doubling time of 15 minutes.

If the population starts with 10 organisms.

We have to determine,

How long would it take for the population to grow to 700 organisms?

According to the question,

A strand of bacteria has a doubling time of 15 minutes.

If the population starts with 10 organisms.

In 15 minutes strand of bacteria has a doubling time the population starts with 10 organisms.

$\rm = 10 \times 2 = 20 \ bacteria$

In 15 minutes 20 bacteria for the population to grow.

In 30 minutes strand of bacteria has a doubling time the population starts with 20 organisms.

$\rm = 20 \times 2 = 40 \ bacteria$

In 30 minutes 40 bacteria for the population to grow.

In 45 minutes strand of bacteria has a doubling time the population starts with 40 organisms.

$\rm = 40 \times 2 = 80 \ bacteria$

In 45 minutes 80 bacteria for the population to grow.

In 60 minutes strand of bacteria has a doubling time the population starts with 80 organisms.

$\rm = 80 \times 2 = 160 \ bacteria$

In 60 minutes 160 bacteria for the population to grow.

In 75 minutes strand of bacteria has a doubling time the population starts with 160 organisms.

$\rm = 160 \times 2 = 320 \ bacteria$

In 75 minutes 320 bacteria for the population to grow.

In 90 minutes strand of bacteria has a doubling time the population starts with 320 organisms.

$\rm = 320 \times 2 = 640 \ bacteria$

In 90 minutes 640 bacteria for the population to grow.

In 120 minutes strand of bacteria has a doubling time the population starts with 640 organisms.

$\rm = 640 \times 2 = 1280 \ bacteria$

In 120 minutes 1280 bacteria for the population to grow.

Hence, In 90 minutes the population to grow to 700 organisms.

8. The graph below shows a dashed line on a coordinate plane. A right triangle is drawn so

Evgesh-ka [11]

Answer:

Option 2

Step-by-step explanation:

First, find the slope of the line of the graph using the points given as (5, -3) and (13, -9):

$slope = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-9 -(-3)}{13 - 5} = \frac{-6}{8} = -\frac{3}{4}$

Any of the triangle in the options given, whose opp side has the same slope value of -¾, is the triangle we are looking for.

Option 1: slope between the points (0, 2) and (3, -2).

$slope = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-2 - 2}{3 - 0} = \frac{-4}{3}$

Option 2: slope between the point (-7, 6) and (-3, 3).

$slope = \frac{y_2 - y_1}{x_2 - x_1} = \frac{3 - 6}{-3 -(-7)} = \frac{-3}{4}$

Option 2 has the same slope as the one given in the graph. This is the answer.

Option 3: slope between the points (5, -1) and (2, -5).

$slope = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-5 -(-1)}{2 - 5} = \frac{-4}{-3} = \frac{4}{3}$

Option 4: slope between the points (2, -7) and (6, -4).

$slope = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-4 -(-7)}{6 - 2} = \frac{3}{4} = \frac{3}{4}$

The answer is Option 2
