To calculate the percentage increase: First: work out the difference (increase) between the two numbers you are comparing. Then: divide the increase by the original number and multiply the answer by 100.

45-32 = 13 / 32 *100= 40.625 round to the nearest percent is 41%

A particular bacterium population is found to double the in 20 minutes. If a laboratory culture
insens350 [35]

The bacteria present at t=37 minutes is found to be 8.40, with no change in growth rate.

<h3>What does population growth exponentially mean?</h3>

When a population's per capita growth rate remains constant, regardless of population size, exponential growth occurs, causing the population to grow exponentially as the population increases.

Given:

P = 340

It has been discovered that a specific bacterial population doubles in 20 minutes.

k = 2/20 = 0.1

t = 37 minutes

We know that,

P = P₀e^{kt}

340   = P₀(e^{0.1*37})

340 =P₀(40.44)

P₀ = 8.40

As a result, the bacteria that will be present in t=37 minutes is found to be 8.40 with no change in growth rate.

Can i please get help with this Question?
sashaice [31]

So firstly, I'm going to be converting the mixed number into an improper fraction. To do this, multiply the whole number by the denominator and then add that product with the numerator and that will be your new numerator. In this case:

3 × 8 = 24, 24 + 3 = 27. \frac{-27}{8}

Now since they have the same denominator, you can subtract the numerators.

\frac{-27}{8}-\frac{7}{8}=\frac{-34}{8}

Now simplify the number as such:

\frac{-34}{8}\div\frac{2}{2}=\frac{-17}{4}

<u>In short, your answer is -17/4, or -4 1/4.</u>

What are the solutions (coordinate points) to the system of equations?
Viefleur [7K]

Answer:

x=0,-2

Step-by-step explanation:

Solve the solution by equaling them to each other and solve for x.

x^2+5x+6=3x+6

x^2+5x-3x+6-6=0

x^2+2x=0 (factor out one x)

x(x+2)=0

x has two solutions since there are two options of solving.

1. x=0/(x+2)

  x=0

2. x+2=0/x

   x+2=0

   x=-2
