After a special medicine is introduced into a petri dish full of bacteria, the number of bacteria remaining in the dish decrease

I am Lyosha [343]

Using the given exponential function, we have that:

Every minute, the number of bacteria decays by a factor of 0.98.

<h3>What is an exponential function?</h3>

A decaying exponential function is modeled by:

$A(t) = A(0)(1 - r)^t$

In which:

A(0) is the initial value.

r is the decay rate, as a decimal.

In this problem, the function is, for the amounts each second:

$Bs(t) = 6000\left(\frac{15}{16}\right)^{t}$

The initial amount is of 6000 bacteria. After 60 seconds = 1 minute, the amount will be of:

$Bs(60) = 6000\left(\frac{15}{16}\right)^{60} = 125$

The decay factor after 1 minute is:

(6000 - 125)/6000 = 98% = 0.98.

Svetradugi [14.3K]

16 regions do not have this type of website . And , $\frac{8}{25}$ fraction of regions do not have this type of website .

<u>Step-by-step explanation:</u>

Here we have , as internet usage grows in a particular country, more and more of its regional governments are placing services online. thirty four out of the fifty regions have web sites that allows residents to file their residents to file their regional income tax online. We need to find how many regions do not have this type of website. what fraction of regions do not have this type of website .Let's find out:

It's given that , thirty four out of the fifty regions have web sites , region which don't have :

⇒ $50-34$

⇒ $16$

So, 16 region don't have this type of website!

Fraction of region that don't have this type of website is :

⇒ $\frac{16}{50}$

⇒ $\frac{8(2)}{25(2)}$

⇒ $\frac{8}{25}$

Therefore , 16 regions do not have this type of website . And , $\frac{8}{25}$ fraction of regions do not have this type of website .

For a party, three solid cheese balls with diameters of 2 inches, 4 inches, and 6 inches, respectively, were combined to form a

schepotkina [342]

Answer:

The radius of the new cheese ball formed is approximately 6.603 inches.

Step-by-step explanation:

We are given the following in the question:

Radius of three cheese ball = 2 inches, 4 inches, and 6 inches

They were combined to form a new cheese ball.

Thus, we can write

Volume of three cheese balls = Volume of new cheese ball.

Let r be the radius of new cheese ball.

Volume of sphere =

$\displaystyle\frac{4}{3}\pi r^3$

Putting values, we get:

$\displaystyle\frac{4}{3}\pi r_1^3 + \displaystyle\frac{4}{3}\pi r_2^3 +\displaystyle\frac{4}{3}\pi r_3^3 =\displaystyle\frac{4}{3}\pi r^3\\\\\frac{4}{3}\pi(2^3 + 4^3 + 6^3) = \displaystyle\frac{4}{3}\pi r^3\\\\2^3 + 4^3 + 6^3 = r^3\\\Rightarrow 288 = r^3\\\Rightarrow r = (288)^{\frac{1}{3}}\\\Rightarrow r \approx 6.603$

Thus, the radius of the new cheese ball formed is approximately 6.603 inches.
