Answer:
$11,714
Step-by-step explanation:
C(x) = 0.7x² - 462x + 87,944
this is a quadratic equation that opens up
the vertex will be the minimum
From the quadratic formula the x coordinate of the vertex is
x = -b/2a
x = 462/(2 * 0.7)
x = 330
Plug in
c(330) = 0.7(330²) - 462(330) + 87,944
c(330) = 11,714
$11,714
Set up the equation in long division form with x-5 outside of the box. Then you want to input the values as you go. Let me know if you want me to clarify my steps.

Step-by-step explanation:
The expression is transformed into its standard form:



The function does not represent a circle, as radius is a positive number.
Answer:
41.24cm²
Step-by-step explanation:
See attachment for the figure
First is to find area of rectangle
Given:
Length of rectangle 'l'= 3cm
breadth of rectangle 'b'= 3cm
Area of rectangle= l x b= 3 x 3=> 9cm²
Next is to find the area of the circle
Given:
radius 'r'= 4cm
Area of circle= πr² => π4² =>50.24cm²
Required:
area of the shaded region=?
area of the shaded region= area of the circle - area of the rectangle
area of the shaded region= 50.24 -9 =>41.24cm²
Therefore, area of the shaded region is 41.24cm²
