Mumz [18]

Answer:

Total = 625x^3 + 125x^2 + 125x

Step-by-step explanation:

Given

Flowers = 25x^2 + 5x + 5

Unit\ price = 5x

Required

The total price for 5 days

First, calculate the total for a day.

1\ day = Unit\ price * Flowers

1\ day = 5x * (25x^2 + 5x + 5)

Open bracket

1\ day = 125x^3 + 25x^2 + 25x

For 5 days, the total will be.

Total = days * sales of a day

So, we have:

Total = 5 * [ 125x^3 + 25x^2 + 25x]

Total = 625x^3 + 125x^2 + 125x

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.

Marizza181 [45]

Using proportions, it is found that the federal tax rate is of 10%.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

The tax rate is the <u>proportion that $17.50 is of $175</u>, hence:

r = 17.50/175 = 0.1 = 10%.

The federal tax rate is of 10%.
