Well if the room is square then you ned to find the square root of the area.
Find 
The tangent line to the curve has slope equal to
at the point (2, -1). We have, by implicit differentiation,


At the point (2, -1), the slope is then 2/9, so the tangent line has equation

Answer:
10
Step-by-step explanation:
Answer:
The answer to your question is below
Step-by-step explanation:
- The Standard form of the equation is
(x - h)² + (y - k)² = r²
4.
Center (8, -4) r =
-Substitution
(x - 8)² + (y + 4)² =
²
-Result
(x - 8)² + (y + 4)² = 118
5.
Center (-10, 9) r = 
-Substitution
(x + 10)² + (y - 9)² =
²
-Result
(x + 10)² + (y - 9)² = 37
6.-
Center (-8, 0) r = 6
-Substitution
(x + 8)² + (y - 0)² = (6)²
-Result
(x + 8)² + (y - 0)² = 36
Answer: 3 ft 8 in
<u>Step-by-step explanation:</u>
The sum of their wingspan is the circumference of the tree.
Use the formula: C = πd to find the diameter (d) of the tree.
5'6" + 6' = 11'6" = 11.5 ft
11.5 ft = πd → 11.5/π = d → 3.66 ft = d
Next, convert the decimal (feet) into inches

which means the decimal of .66 ft rounds to 8 in
⇒ d = 3 feet 8 inches (3' 8")
