A rectangular field is 3 yards longer than twice its width. If the perimeter is 156 yards. How wide is the field? 3*2=6 6*2=12 6*2*12=156 ??

Do we really need to know all of this for the lecture AND lab?? Are these going to be on the test?

the number of formula units is 4: there are 4 Sulfur atoms in the unit cell (8* 1/8 + 6* 1/2) and 8 Lithium atoms (all contained within the unit cell)

This problem can be solved by converting the distances into improper fractions. To turn mixed numbers into improper fractions, simply take the whole number and multiply it by the fraction's denominator and then add the numerator. You take this new number...

The limit is 0. You can see what a limit will approach by first plugging the number into the function. As x approaches 0, the function will be 0*e^(cos(1/0)). Since there is a 1/0 in the function, we know that the value of the function is undefined at x=0...

Each company is willing to pay $120,000 and there are 7 companies. Just multiply $120,000 seven times and you will get $840,000.

The equation of the tangent line can be represented by the point-slope format which is y-y0=m(x-x0). The point of interest is x=pi. Since there is no y0 coordinate provided, the tangent line equation will be in the form y=m(x-x0). To calculate the slope(m...

Thank you for setting up the equation, I'm happy I understood it. Although the final answer was off, it wasn't by much, you forgot to divide to get 200. Very grateful for the way you set it up though.

I do!
