Suppose that the number of bacteria in a certain population increases according to an exponential growth model, with a growth ra

podryga [215]

Answer: 5489

Step-by-step explanation:

Given the following :

Growth rate (r) = 19% per hour

Sample culture in population = 2300

Size of sample after 5 hours =?

Using the exponential relation:

P = Po * r^t

P = population after 5 hours

Po = Initial sample population

t = time

P = 2300 * (1 +19%)^t

P = 2300 ×(1 + 0.19) ^5

P = 2300 * 1.19^5

P = 2300 * 2.3863536599

P = 5488.61341777

P = 5489 (nearest integer)

Steps on how to Solve 7 - 2p > -5

ale4655 [162]

Hello!

Answer:

p<6

*The answer must have a positive sign and less than symbol sign.

Step-by-step explanation:

First, you subtract by 7 from both sides of an equation.

$7-2p-7>-5-7$

Then, simplify.

$-2p>-12$

Next, multiply by -1 from both sides of an equation.

$(-2p)(-1)$

Simplify.

$2p$

You can also divide by 2 from both sides of an equation.

$\frac{2p}{2}$

And finally, simplify and solve. You can also divide by the numbers.

$12/2=6$

Final answer: $p$

Hope this helps!

Thanks!
