Step-by-step explanation: First you figure out your expression: 7/8 - 1/2. Then you find a common denominator, which will be 8. To make one-half have a denominator of 8, multiply by 4/4. 1/2*4/4=4/8. To finish, subtract 7/8-4/8 and you get 3/8.
Today’s topic is drugs. marijuana, in fact study’s show that nearly 55 million adults use marijuana and that’s most likely not including all the young teens that do too.
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).
