The nth term of the geometric sequence is:
an=ar^(n-1)
where
a=first term
r=common ratio
n=nth term
from the question:
120=ar(3-1)
120=ar^2
a=120/(r^2)....i
also:
76.8=ar^(5-1)
76.8=ar^4
a=76.8/r^4.....i
thus from i and ii
120/r^2=76.8/r^4
from above we can have:
120=76.8/r²
120r²=76.8
r²=76.8/120
r²=0.64
r=√0.64
r=0.8
hence:
a=120/(0.64)=187.5
therefore the formula for the series will be:
an=187.5r^0.8
C no solution because yeah
The variable of interest would be whether or not their eyes were affected.
Variables of interest are like independent variables, they are the variable that you are testing for change.
19/8 is the improper fraction of 2 3/8.
Answer:
The line passing through the given points is:
in its slope-intercept form
Step-by-step explanation:
Start by finding the slope of the segment that joins the two given points using the slope formula:
which for our case renders:
Now we can find the y-intercept by using any one of the given points in the general slope-intercept form of a line with this slope:
Therefore, the equation of the line becomes:
