Answer:
0.264 mm
Step-by-step explanation:
Number of sheets = 1000
Thickness of entire sheet = 264 mm
The thickness of the sheet is :
Thickness of entire sheet / number of sheets
264 mm / 1000
= 0.264 mm
Answer:
an=1*2.5^(n-1)
=2.5^(n-1)
Step-by-step explanation:
Complete question below:
What value, written as a decimal, should Lena use as the common ratio? Lena is asked to write an explicit formula for the graphed geometric sequence. On a coordinate plane, 3 points are plotted. The points are (1, 1), (2, 2.5), (3, 6.25).
Solution
Point (1, 1), (2, 2.5), (3, 6.25).
a=1
ar=2.5
ar^2=6.25
From ar and ar^2
r=6.25/2.5
=2.5
r=2.5
an=ar^(n-1)
Therefore, the explicit formula is
an=1*2.5^(n-1)
=2.5^(n-1)
Answer:
0.1 is 0.1265525 rounded to the nearest tenth
Answer:
r= 9
Step-by-step explanation:
radius (r) = diameter (D)/2
= 18/2
= 9
answer: -5x+12=20
-12 -12
-5x/-5= 8/-5
x= -1.6
