A school of fish has the population of 200. The population is decreasing at a rate of 5% a year how can you write in exponential decay function to find the quarterly decay rate

Step-by-step explanation:

Initial population of fish = 200

Decay rate by which population is decreasing = 5% per year

Number of quarters in a year = 4

Rate of decay in a quarter = = 1.25%

Formula for the exponential decay in the population is,

Here, P = Final population

P₀ = Initial population

r = Rate of decay per quarter

n = Number of quarters for the total decay

By substituting these values in the formula,

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
