Answer:
The tip was 30% percent
Step-by-step explanation:
All you have to do is the following, total price difference/ original price. 4.20/14 is 0.3, so 30 percent.
5. The number of visitors increase in April, spike in August and then decrease in September.
6. December is in winter, therefore many people do not travel during December.
7. There are not a lot of holidays in February and March, so people are either working or going to school instead of visiting.
I hope this helped!
The slope is 5/7
4-(-1)=5 which is the Y value
5-(-2)=7 which is the X value
Slope =Y/X
The sum if the geometric sequence given by:
an=-2(3)^(n-1)
will be:
when:
n=1
an=-2
when n=2
a2=-6
when n=3
a3=-18
when n=4
a4=-54
when n=5
a5=-162
when n=6
a6=-486
when n=7
a7=-1458
when n=8
a8=-4374
thus the summation of the term will be:
Sn=(-4374+-1458+-486+-162+-54+-18+-6+-2)
Sn=-6560
the answer is -6560
