Answer:
D.12
Step-by-step explanation:
The first thing is to determine the two integer sets, which we will start with the number 1, therefore the first would be:
{1,2,3,4}
We know that it has a number in common, which in this case would have to be 4, therefore, the other set would be:
{4,5,6,7}
Therefore the sets are:
{1,2,3,4}; {4,5,6,7}
Now to calculate the difference between the sum of the integer between them it would be:
(5 - 3) + (6 - 2) + (7 - 1)
= 2 + 4 + 6
= 12
The answer then would be D.12
( - 5 x² + 8 x ) + ( 2 x² - 3 x + 7)
= - 5 x² + 8 x + 2 x² - 3 x + 7
= - 3 x² + 5 x + 7
7 - 2 = 5
5 / 5 = 1
The answer would be 1.
Answer:
11 years
Step-by-step explanation:
we know that
The formula to calculate the depreciated value is equal to
where
V is the depreciated value
P is the original value
r is the rate of depreciation in decimal
x is Number of Time Periods
in this problem we have
substitute in the formula
Apply log both sides
