A = (pi) * r*2
(pi) = 3.14
r = d/2.....r = 17/2 or 8.5

A = 3.14 * 8.5^2
A = 3.14 * 72.25
A = 226.86 rounds to 226.9 m^2 <==

Meredith's recipe for 2 1/2 dozen cupcakes calls for 3 cups of flour. She only has 1 cup of flour and needs to feed 12 people. C

oee [108]

I am pretty sure the awnser is yes because 2.5 divided by 3 equals .83 repeating which mean for one dozen of cupcakes(12) it would take .84 cups of flour.

Answer:

The equation of demand function is

$y=-\frac{1}{2000}x+29$

Step-by-step explanation:

We have two point demand function

(38000,10) and (42000,8)

Here $x_1$ =38,000, $y_1$ =10, $x_2$ =42000, $y_2$ =8

The slope of the demand function line is

$=\frac{y_2-y_1}{x_2-x_1}$

$=\frac{8-10}{42000-38000}$

$=\frac{-2}{4000}$

$=-\frac{1}{2000}$

The equation of demand function is

$y-y_1=m(x-x_1)$

$\Rightarrow (y-10)=-\frac{1}{2000}(x-38000)$

$\Rightarrow y-10=-\frac{1}{2000}x+\frac{38000}{2000}$

$\Rightarrow y=-\frac{1}{2000}x+19+10$

$\Rightarrow y=-\frac{1}{2000}x+29$
