Remember, an=a1(r)^(n-1) where a1=first term or where n=1 and r=commmon ratio
<span>
</span>
a2/a1=r
<span>
</span>
so if you have the graph, find the y value coresponding to x=1 and that is a1
<span>
</span>
find the y value coresponding to x=2 and taht is a2, do a2/a1 to get r
so like I was saying
well, each term is 1/2 of the previous
20/40=1/2
so r=1/2
and a1=40
so
is da equation
Answer:
Step-by-step explanation:
Let's start with the equation of the volume of a cylinder:
Where:
- r is the radius of the cylinder (r=D/2=24/2=12 cm)
- h is the high of the cylinder (h = 60 cm)
We can us partial derivatives to find the differential of this volume. So we will have:
(1)
Now:
dr is a differential of the radius, so in our case it is 0.1 cm and dh, differential of the high, is 0.1*2 cm. We multiply by 2 because we need to consider the top and the bottom of the cylinder.
Now we just need to put all of this definitions in the equation (1).
I hope it helps you!
The answer would be 4. If you turn it to decimals, which would be 1.25 and 2.75, added together, it would be 4.
