Answer: Choice A
four and eighty three hundredths with the three repeating
In other words, 4.8333...
====================================================
Explanation:
Use long division to find that 5/6 = 0.8333... where the 3s go on forever. The steps for the long division are shown in the diagram below. You can use a calculator to confirm.
Therefore, 4 & 5/6 = 4 + 5/6 = 4 + 0.8333... = 4.8333...
Since the 3 repeats forever, we can use a horizontal bar to place over the 3 like this
Don't be shy about using actual parentheses and commas.
Line through (1,8) perpendicular to
The perpendicular family is gotten by swapping the coefficients on x and y, negating exactly one of them. The constant is given directly by the point we're through:
Let's clear the fractions by multiplying both sides by 20.
Might as well stop here.
Answer: 25 x + 16 y = 153
A function that depicts depreciation can be represented as equations, graphs and tables.
<h3>The yearly value of each car for the first five years</h3>The functions are given as:
Where:
C = 5895 --- the initial value of the car
r = 22% --- the rate of depreciation
For the first 5 years, the values of t = 1, 2, 3, 4 and 5
For the first function, we have:
For the second function, we have
So, the table of values is:
See attachment for the graphs of the two functions
<h3>Interpreting the graphs</h3>The graph of car 1 increases up to C(t) = 5895, and then remains constant as the value of t increases while the graph of car 2 follows an exponential pattern.
This means that, the graph 2 that follows an exponential pattern is more realistic
<h3>The worth of the cars after 5 years</h3>From the table, the worth of car 1 is $5892.0, while the worth of car 1 is $1702.0
