Each year the boat is worth 100-12 = 88% ( or 0.88) of the year before
after 12 years the boat is worth 12050 * 0.88^9 = $3813.56
Answer:
C
Step-by-step explanation:
I used a fancy calculator and that's what is gave me I use it on math tests and pass
A logarithm is defined as a power to which a number must be raused to in order to get another number. For example,
This is because
So if we have
We have to determine what number must 10 be raised to in order to give 13 so we have
The first thing you should do for this case is to use the following table to perform the equation of a line:
y x
41,431 1995
48,729 2005
We have then that the line that best fits this data is
y = 729.8x - 1E + 06
Then, to know in what year the number of shopping centers reaches 80,000 we must replace this number in the equation of the line and clear x:
80000 = 729.8x - 1E + 06
Clearing x
x = (80000 + 1E + 06) / (729.8) = 1479.857495
nearest whole number
1480
This means that after 1480 years, 80000 shopping centers are reached.
Equivalently, this amount is reached in the year:
1480 + 1995 = 3475
In the year 3475
answer
(a) y = 729.8x - 1E + 06
(b) In the year 3475
Answer:
y=-11
Step-by-step explanation:
A line can be represented by a linear equation of
where m is the slope and y is the y intercept.
The slope is 0 so this function will be
Which is also called a constant function. The y intercept is -11. So the answer is
