A spherical balloon is inflated with gas at the rate of 800 cubic centimeters per minute. How fast is the radius of the balloon increasing at the instant the radius is 30 centimeters. *Completely reduce and do not change into decimal form. The # of cups will be the numerator.

Given:

Step 1: Differentiate with respect to r

Step 2: Solve for

Step 3: Plug in known variables

Solve:

r=30 cmr=30 cm

2 eggs

optimal Water

A farmer plans to fence a rectangular pasture adjacent to a river. The pasture must contain 245,000 square meters. What dimensions will require the least amount of fencing if no fence is needed along the river. *Divide the smaller number over the larger number to get the number of cups of water.

xy=245,000 S=length of fence needed=x+2yStep 1: Set-up

equation

Step 2 & 3: Differentiate, set equal to 0 & solve for x

x=700

Step 4: Plug in x-value to find y-value.

700y=245,000y=350

*Divide the smaller number over the larger number to get the number of cups of water.

350/700=1/2

½ cup of water

Don’t forget to check that the

second derivative will be

> 0

differential Milk

Find the particular solution of that satisfies (0,1/2).

Step 1: Separate the variables

Step 2: Integrate =

Step 3: Plug in variables to solve for C

¾ cups of milk

Flour

Locate the absolute the extrema of f(x)=2x-3 over the interval (0,2]. *The y-value will indicate the number of cups of flour.

Step 1: Differentiate

f(x)=2x-3f’(x)=2

Step 2: Plug in x to find y.

f(2)=2(2)-3f(2)=1

(2,1)

1 cup of flour

Finished!

2 large eggs 3/4 cup milk 1/2 cup water 1 cup flour Butter, for coating the pan

Directions In a blender, combine all of the ingredients and pulse for 10 seconds.

Place the crepe batter in the refrigerator for 1 hour. This allows the bubbles to subside so the crepes will be less likely to tear during cooking. The batter will keep for up to 48 hours.

Heat a small non-stick pan. Add butter to coat. Pour 1 ounce of batter into the center of the pan and swirl to spread evenly. Cook for 30 seconds and flip. Cook for another 10 seconds and remove to the cutting board. Lay them out flat so they can cool. Continue until all batter is gone. After they have cooled you can stack them and store in sealable plastic bags in the refrigerator for several days or in the freezer for up to two months. When using frozen crepes, thaw on a rack before gently peeling apart.

Great job! Our recipe is

completed and now it’s time to

enjoy some crepes!
