Answer: 77 CD’s

Step by step:
Since we are writing a proportion it will look like this .....
33/1.5 = x/3.5 ( 33 over 1.5 and x over 3.5)

Now that we have our proportion , you cross multiply.....
33 x 3.5 = 115.5
“X” x 1.5 = 1.5x
So now you will have an equation that looks like this....... 1.5x=115.5
Once you have that then you divide 1.5 from each side , then after that then you should have x=77
So it takes 77 CD’s to be in a 3.5 inch high stack .
Hoped this helped , if it didn’t I apologize
Good luck

For the function P(x) = x3 − 9x, at the point (2, −10), find the following. (a) the slope of the tangent to the curve (b) the in
Shalnov [3]

Answer:

3, in both a), b)

Step-by-step explanation:

a) The slope of the line tangent to the curve that passes through the point (2,-10) is equal to the derivative of p at x=2.

Using differentiation rules (power rule and sum rule), the derivative of p(x) for any x is p'(x)=3x^2-9. In particular, the value we are looking for is p'(2)=3(2^2)-9=12-9=3.

If you would like to compute the equation of the tangent line, we can use the point-slope equation to get y=3(x-2)-10=3x-16

b) The instantaneus rate of change is also equal to the derivative of P at the point x=2, that is, P'(2). This is equal to p'(2)=3.
