The population of bacteria doubles every 6 hours. By how much will it grow in three days. Write the equation

ch4aika [34]

Answer:

Step-by-step explanation:

let x be the population

so we have ,

2x= 6h

?= 3 days or 3×24h

by cross multiplication we have

2x× 72h= 6h×?

?= 2x×72/6 = 24x

So, in three days the bacteria will b 24 times current population.

What is the slope of the line through (-9, 6) and (-3, 9)?<br> Choose 1 answer:

trasher [3.6K]

Given: Points (-9, 6) and (-3, 9)

Find: The slope of the line that goes through those two points

Solution: In order to find the slope of the line that goes through the points that were provided we have to use the slope formula. This formula subtracts the y-coordinates from each other and also the x-coordinates from each other to determine the rise/run which would give us the rate of change.

<u>Plug in the values</u>

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{9 - 6}{-3 - (-9)}$

<u>Simplify the expression</u>

$m = \frac{3}{-3 + 9}$

$m = \frac{3}{6}$

$m = \frac{1}{2}$

Therefore, looking at the given options we can see that the best fitting one would be option A, 1/2.

Veronika [31]

Answer:

The total amount of meters in one lap is 966

Step-by-step explanation:

we know that

The total amount of meters in one lap is the same that the perimeter of the rectangular playground

The perimeter of the rectangular playground is equal to

$P=2(L+W)$

we have

$L=320\ m\\W=163\ m$

substitute

$P=2(320+163)$

$P=966\ m$

<h3>How to find the free fall formula for a given scenario</h3>

An object experiments a free fall when it is solely accelerated by gravity on the assumption of an <em>uniform</em> acceleration. The formula is described below:

$h =h_{o} + v_{o}\cdot t + \frac{1}{2}\cdot g\cdot t^{2}$ (1)
