Step-by-step explanation:
PART A: The area of a circle is radius squared times pi. To estimate the radius, you have to divide the area by pi (estimate 3.14) and then find the square root of the quotient
600/3.14=191.0828...
Square root/radius is about 13 sq feet
PART B:
Now use the pi button instead of 3.14 and do the same thing.
Square root/radius is about 16.9 feet
PART C: Since it's the radius squared and you are doubling it again, it would be radius squared times radius squared, or radius to the fourth power...meaning the area would quadruple.
Reasoning is valid. Area if radius was doubled would be about 3589 feet. ROund to 3600, which divided by 900 is 4

Step-by-step explanation:
Absolute Value Equation entered :
3|3x-9|=18
Step by step solution :
Step 1: Rearrange this Absolute Value Equation
Absolute value equalitiy entered
3|3x-9| = 18
Step 2: Clear the Absolute Value Bars
Clear the absolute-value bars by splitting the equation into its two cases, one for the Positive case and the other for the Negative case.
The Absolute Value term is 3|3x-9|
For the Negative case we'll use -3(3x-9)
For the Positive case we'll use 3(3x-9)
Step 3: Solve the Negative Case
-3(3x-9) = 18
Multiply
-9x+27 = 18
Rearrange and Add up
-9x = -9
Divide both sides by 9
-x = -1
Multiply both sides by (-1)
x = 1
Which is the solution for the Negative Case
Step 4: Solve the Positive Case
(3x-9) = 18
Multiply
9x-27 = 18
Rearrange and Add up
9x = 45
Divide both sides by 9
x = 5
Which is the solution for the Positive Case
Step 5: Wrap up the solution
x=1
x=5
Solutions on the Number Line
Two solutions were found :
x=5
x=1
Answer:
Step-by-step explanation:
make a good drawing and notice the right triangle with legs 20 mi and 14 mi
the distance from home to the warehouse is the hypotenuse c of the right triangle thus we will use the Pythagorean Theorem:
c^2 = 20^2 + 14^2
c^2 = 596
c = 24.41 mi approximately is the distance from home to a warehouse
since 24.41 < 25 you will incur a delivery charge.
