What is the derivative of pi?

vredina [299]

A "derivative" is a rate of change.

The derivative of a plain old number is zero, since numbers never change.

Pi is a number. Its value never changes. Its derivative is zero.

Find the area of this figure (50 points)

Softa [21]

Answer:

$A_{total} = 14\ in^2$

Step-by-step explanation:

Step 1: Determine the area of the left rectangle

We can tell that the total shape seems like two rectangles glued together. We can separate the left rectangle and determine the area of it and then determine the area of the right rectangle and combine them. Lets first solve the left rectangle.

$A = l * w$

$A_{left\ rectangle} = 2\ in * 4\ in$

$A_{left\ rectangle} = 8\ in^2$

Step 2: Determine the area of the right rectangle

$A = l * w$

$A_{right\ rectangle} = 3\ in * 2\ in$

$A_{right\ rectangle} = 6\ in^2$

Step 3: Determine the total area

$A_{total}=A_{left\ rectangle} + A_{right\ rectangle}$

$A_{total} = 8\ in^2 + 6\ in^2$

$A_{total} = 14\ in^2$

Answer: $A_{total} = 14\ in^2$

A cake recipe requires 3 1/4 cups of flour for 13 servings and 4 1/2 cups of flour for 18 servings.How much flour is required to

slamgirl [31]

To solve, set up a proportion

3.25 cups x cups
---------------- = ---------------
13 servings 28 servings

Now cross multiply

13x = 28 * 3.25

Simplify.

13x = 91

Divide both sides by 13

x = 7 cups

To check your answer, use proportions again, but change the left side to 4.5 cups over 18 servings, use the same steps, if the answer is the same as above, then the answer is correct
