The outside of the table represents the circumference and the formula for circumference is diameter times pi (simplified to 3.14). diameter is two times the radius so in this case we multiply 2 1/4 or 2.25 by two and we get 4 1/2 or 4.5. Now that we have the diameter, just multiply by 3.14 to get 14.13 feet for the circumference (:

Answer: See Explanation
Step-by-step explanation:
The price elasticity of demand will be calculated as:
q = 860 − 20p.
dq/do = -20
p = 38
Elasticity E(p) = (p/q) × dq/dp
= [38 /(860 - 20p)] × (20)
=38 × 20/(860 - 760)
= 7.6
Therefore, the price elasticity of demand when the price is $38 per orange is 7.6
Revenue = price × quantity
= p × q
= p × (860 − 20p)
= 860p - 20p²
Differentiating with respect to p
= 860 - 40p
40p = 860
p = 860/40
p = 21.50
Maximum Revenue = 860p - 20p²
= 860(21.50) - 20(21.50)²
= 18490 - 9245
= 9245
Answer:
(x-7)(x+7)
Step-by-step explanation:
x^2 -49
This is the difference of squares
x^2 -7^2
We know that a^2 -b^2 = (a-b)(a+b)
(x-7)(x+7)
