Answer:
(A)
Step-by-step explanation:
Given a set with "n" number of elements, the collection of all subsets of the set is referred to as the Power set of the given set.
To find the number of possible subsets of any set, we use the formula:
Take for example the set: A={2,3,4)
A has 3 elements, therefore n=3
The number of possible subsets of A is:
To graph the line we need two points; we already have one the point (4,2) now we need to find another one; to do this we get the equation of the line given by:
where m is the slope and (x1,y1) are a point throught the line. Plugging the values given we have:
Now we give a value to x and find the corresponding y. If x=0, then:
hence we have the point (0,-2).
Now that we have two points (0,-2) and (4,2) we graph them on the plane and join them with a straight line, hence the graph is:
Answer:
Equation to represent the situation =
Step-by-step explanation:
Given:
Initial investment = Y
Growth rate (r) = 5% = 5 / 100 = 0.05
Number of year (n) = X year
Amount after X year = $800
