Answer:
Step-by-step explanation:
Let and :
<u>Determine slope</u>
<u>Use either coordinate point to find "b", the y-intercept</u>
<u>Final Equation</u>
The surface area of a sphere is A = 4 π R² .
Sadly, the question doesn't give you 'R', so you have to
back it out of the circumference.
Circumference = π (diameter)
Divide each side by π : Diameter = circumference / π
Radius = 1/2 diameter: Radius = circumference / (2 π)
Area = 4 π R² =
4 π (circumference/2π)² =
4 π (circumference)² / 4 π²
Divide top and bottom by 4π : Area = (Circumference)² / π
Circumference = 37.68 units
Area = (37.68)² square units /π =
<em>451.93 square units</em>
$120 because the fencing of the patio would use up eight squares and each square in the picture is 3 meters so we would need 24 meters of fencing to cover up the entire patio. Since it cost $5 for one meter, 5*24 is $120.
Answer:
I understand how to solve quadratice equations, but what do you do if it is equal to f(x). I am guessing that you set if equal to 0, but could anyone confirm?
f(x) = x^2 -6x +13. As an example. Have a great day
