A scientist is conducting an experiment on two types of bacteria to determine which type will grow faster in a pool. After colle

cting data for two weeks, she finds that she can model the growth rates as follows: Bacteria 1: y = 4x Bacteria 2: y = 4x2 In these models, y represents the number of bacteria colonies and x represents the number of hours. Based on these models, which type of bacteria is growing faster? bacteria 1

Answer: bacteria 2

Step-by-step explanation:

Since the growth rates are modeled as : Bacteria 1: y = 4x

And Bacteria 2: y = 4x2

Where y represents the number of bacteria colonies and x represents the number of hours.

Let's plug in for the two models

By assuming x = 2 and x = 3

If x = 2

Bacteria 1 will be y = 8 and bacteria 2 will be y = 16

Based on these models, bacteria 2 is growing faster than bacteria 1 because the growth is exponential

Find the points on the curve where the tangent line is horizontal . x=4(cosθ-cos^2θ) , y=4(sinθ-sinθcosθ)
taurus [48]
X = 4(cosθ - cos²θ) = 4cosθ - 4cos²<span>θ
</span>dx/dθ = -4sinθ + 8sinθcosθ = -4sinθ(1 - 2cos<span>θ)

dy/d</span>θ = 4(cosθ - cos²θ + sin²θ) = 4(cos<span>θ - 1)

</span>∴dy/dx = 4(cosθ - 1)/-4sinθ(1 - 2cosθ) = 1-cosθ/(sinθ - 2sinθcosθ<span>)
Now, we're finding a horizontal tangent, which is when dy/dx = 0 (horizontal tangent).
1-cos</span>θ/(sinθ - 2sinθcosθ) = 0
1-cosθ = 0
cosθ = 1

θ = 0, 360 in the interval [0, 360].
At θ = 0, x = 0, y = 0

Only points in the open interval [-2π, 2π] are at (0, 0), unless I made a mistake somewhere.

What is 30% of 75 in math?
nika2105 [10]
The answer is 22,5

To understand percents and how to calculate them it is most important that you remember that one whole is divided into one hundred little peaces. In this case, the whole is 75. So, the easiest way to find a certain percentage of a whole, is to divide it by one hundred and then multiply it with the percent that you want to find. So, to solve your question you have to divide 75 by 100, which gives you that one percent of 75 is 7.5, and then to find what 30 percent of 75 is, you multiply that one percent by 30, or 7.5 x 30, which gives you 22.5 - the wanted solution. 

There are other ways of calculating percentage, but this is by far the easiest one for beginners to understand. 

Hope it helps :)
