Fill in the point values in the formula for the derivative.
____
<u>Example</u>
y = x^2 + 3x . . . . . we want y' at (x, y) = (1, 4)
y' = 2x +3 . . . . . . . take the derivative dy/dx of the function
Fill in the value x=1 ...
y' = 2·1 +3 = 5
The value of the derivative at (x, y) = (1, 4) is 5.
Use the information to form an equation
x = width
x + 6 = length
perimeter = length + length + width + width
x + x + x + 6 + x + 6 = 44
4x + 12 = 44
4x = 32
x = 32/4
x = 8
width = 8 meters
length = 8 + 6 = 14 meters
9000 is a 4 digit number that is divisible by 9 and 8. ( 9000/9 = 1000) and ( 9000/8 = 1125 )
You have to find the unit rate, which in this case means the amount of fish you need per serving of soup.
If 16 oz of fish makes 24 servings, then 16/24 oz = 2/3 oz makes 1 serving.
Now multiply both quantities by 10, so that 10 servings require 20/3 oz ≈ 6.67 oz of fish.
A more direct way to do this is to solve for <em>x</em> in the following equation:
(16 oz fish) / (24 servings) = (<em>x</em> oz fish) / (10 servings)
Then (omitting units)
<em>x</em> = 10 • 16 / 24 = 20/3
It doesn't say anything about him.
