Answer:

The size of the sample after four hours is of 3158 bacteria.

Step-by-step explanation:

The population after t hours can be modeled by the continuous exponential growth model, which is:

P(t) = P(0)e^{rt}

In which P(0) is the initial population and r is the growth rate paremeter.

A growth rate parameter of 17% per hour.

This means that r = 0.17

Suppose also that a sample culture of 1600 is obtained from this population.

This means that P(0) = 1600

Find the size of the sample after four hours.

This is P(4).

P(t) = P(0)e^{rt}

P(t) = 1600e^{0.17t}

P(4) = 1600e^{0.17*4}

P(4) = 3158.2

Rounding to the nearest integer

The size of the sample after four hours is of 3158 bacteria.

Selena buys 4 peaches that weigh 1 pound in all. Each peach weigh the same amount. Peaches are on sale for $2.24 per pound. Writ
DENIUS [597]

Answer:

The required equation is

4p = 2.24

And p = 0.56  [ where p is in $]

Step-by-step explanation:

Given that Selena buys 4 peaches that weight 1 pound in all.

Peaches are on sale for $2.24 per pound.

Since the total weight of peaches is 1 pound.

So the price of 4 peaches is $2.24.

Let p be the price of 1 peaches.

Then the price of 4 peaches is $(4×p)

                                                  = $4p

According to the problem,

4p = 2.24

\Rightarrow p=\frac{2.24}{4}

⇒p=0.56      [ where p is in $]

The required equation is

4p = 2.24

And p = 0.56  [ where p is in $]
