Answer:Roots: 3;2;-1
Step-by-step explanation: i use horner's scheme for approximating the roots of polynomials
Area of a circle=πr²
area of this cirlce=π*(12 ft)²=144π ft²≈452.39 ft².
answer 1= the area of this circle is 452.39 ft².
Perimeter of a circle=2πr.
Perimeter of this cirlce=2π(12 ft)=24π ft≈75.4 ft
<span>answer 2= the perimeter of this cirlce is 75.4 ft.</span>
Answer:
Part a) Exactly values
The width of the rectangle is 
The length of the rectangle is 
Part b) Approximately values
The width of the rectangle is 
The length of the rectangle is 
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
The area of rectangle is equal to

we have

substitute the values in the formula



so

Solve for x
Divide by 4 both sides

square root both sides

The solution is the positive value

therefore
<em>Exactly values</em>

<em>Approximately values</em>

Answer:
C
Step-by-step explanation:
Convert 8 1/2 to 17/2 and this multiplied by 3 is 51/2. Convert it back to mixed fraction to get 25 1/2.
