Answer: 3,029.56

Explanation:

Hi, to answer this, first, we have to calculate the percent increase per day:

Since the value grows exponentially at a rate of 1.5% every 9 hours, if we divide the rate by 9, we obtain the percent increase per hour.

1.5 /9 = 1/6% per hour

Since a day has 24 hours, by multiplying the hour increase by 24 we obtain:

1/6 x 24 = 4% per day

4% = 4/100 = 0.04 decimal form

Now, we have to apply exponential growth formula:

y = a (1+r )^x

Where:

a= initial value

r = growth rate

x = time interval

Replacing with the values given:

3000 ( 1 + 0.04)^x

solving for x = 0.25

3000 ( 1 + 0.04)^0.25 =3,029.56

How are industrialization and unplanned urbanization responsible for environmental pollution?Describe. ​
denis-greek [22]

Answer:

Industrialisation usually requires the use of potentially polluting technologies which can generate waste products that can pollute the air, water and soil.

It is entirely up to both governments and the individuals undertaking the industrialisation to ensure that pollution is kept to an absolute minimum, preferably non-existent. However, this can sometimes add to the cost of the products produced so is often overlooked or ignored by both government, who want greater tax revenue, and the individuals, who want a higher profit, at the expense of the environment - often until it is too late to prevent severe damage.
