Answer:
Part a) The approximate years were 1998 and 2008
Part b) The graph in the attached figure
Step-by-step explanation:
Part a) we have
For
Solve the quadratic equation
we know that
The formula to solve a quadratic equation of the form is equal to
in this problem we have
so
substitute in the formula
therefore
The approximate years are
1997+11=2008
1997+1=1998
Part b)
Using a graphing tool
we have
The solution of the system of equations is the intersection point both graphs
The intersection point are (0.99,80) and (11.23,80)
see the attached figure
therefore
The solution part a) is correct
Answer:
C
Step-by-step explanation:
The solution is the dot where the two equations meet, so that's why I compared them. You can also see it in the graph itself.
Answer:
Irrational, because it is non-terminating and non-repeating So Its Irrational.
Answer:
whole
Step-by-step explanation:
No question is posed.
If we assume we're interested in the number of cars sold on Monday, we have ...
part = percent × whole
14 = 56% × whole
It would seem that we're looking for the whole.
__
14/.56 = 25 cars were sold on Monday.
6th graders = 52%
7th graders = 0.57x100 = 57%
8th graders = 2/5 x 100 = 40% so least to greatest will be
8th, 6th then 7th
