Nathan opens a new savings account and makes an initial deposit of $400.

if the account earns 2% annual interest, how much interest will he earn in 9 months?

$6

Step-by-step explanation:

To find how much Nathan will get in 9 months, we use the formula:

Let's break down the variables that we have.

I = ?

P = 400

r = 2% or 0.02

t = 9/12 or 0.75

The time is 0.75, because the interest is applied annually.

Now let's plug in our values to the formula.

Nathan will earn $6 in interest in 9 months.

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

the population of other specie of birds will decline or other specie of birds will find some alternate source of food to survive.

explanation:

according to the competitive exclusion principle, which is also known as gause's law, two specie living in the same niche and feeding on the same resource cannot co-exist stably.

as we have well studied the theory of natural selection which states that only those organisms survive which have better tendency to compete for food and adapt to the environmental conditions.

coming towards the question, what wi ll happen when one species outcompetes the other for the small fish , the other specie will not get enough food and will start to die or decline in population. eventually either other specie needs to find another alternative food source for itself or migrate at some other location where there is less competition otherwise it will just not exist anymore at that niche.

hope it !
