To determine the thickness of the film, we assume the shape of the film is in a form of cylinder where the thickness is equal to the height. The volume of a cylinder is expressed as:

V = pi (r^2) h

We calculate as follows:

0.23 = pi (10^2) (h)
h = 0.0007 cm

Step-by-step explanation:

length is 24 inches after the increase and width is 33 inches (i did length as up and down and width as side to side, that's how I always do it but I might be wrong let me know and I can fix it)

viva [34]

Answer:

slope = \frac{1}{2}

Step-by-step explanation:

Calculate the slope m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (- 8, 0) and (x₂, y₂ ) = (4, 6) ← 2 points on the line

m = \frac{6-0}{4+8} = \frac{6}{12} = \frac{1}{2}

raketka [301]
I will assume it is 2.5% interest rate over 2 years and not per year. If this isn’t the case then let me know.

Well $1250 divided by 100 = $12.50
This is 1%-

To make 2.5% we do-> $12.50 x 2.5= $31.25
This makes our interest rate $31.25

To get our total amount.....
$1250 + $31.25 = $1281.25
