Find the value of y.​

Mathematics
1 answer:
Bess [88]3 years ago

Answer:

=6√3 the third option.

Step-by-step explanation:

We can use the Pythagoras theorem to find the value of y. We need two equations that include y.

a²+b²=c²

c=9+3=12

x²+y²=12²

x²=144 - y².........i (This is the first equation)

We can also express it in another way but let us find the perpendicular dropped to c.

perpendicular²= x²-3²=x²-9 according to the Pythagoras theorem.

y²=(x²-9)+9²

y²=x²+72

x²=y²-72....ii( this is the second equation

Let us equate the two.

y²-72=144-y²

2y²=144+72

2y²=216

y²=108

y=√108

In Surd form √108=√(36×3)=6√3

y=6√3

The weekly sales of Honolulu Red Oranges is given by
Volgvan

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
