An airline finds that if it prices a cross-country ticket at $300, it will sell 400 tickets per day. It estimates that each $10
lions [1.4K]

Answer:

price = $190

quantity =  950 tickets

Step-by-step explanation:

revenue = price * quantity

n = number of $10 price reductions

price = 300 - 10n

quantity =  400 + 50n

r = (300 - 10n)(400 + 50n)

recognize these as the factors of a quadratic that opens down

the vertex will therefor be the maximum revenue

the roots are:

300 - 10n = 0

300 = 10n

n = 30

400 + 50n = 0

50n = -400

n = -8

vertex is at mid point of the roots

n = (-8 + 30)/2

n = 11

price = 300 - 10n

price = 300 - 10(11)

price = 190

quantity =  400 + 50n

quantity =  400 + 50(11)

quantity =  950

If a force of 50 pounds is directed 30° from the horizontal, what vector represents this force?
Elan Coil [88]

Answer:

F_x=43.30\ N

Step-by-step explanation:

Given that,

Force, F = 50 pounds

It is directed at 30° from the horizontal.

The force will be given by :

F_x=F\cos\theta\\\\=50\times \cos(30)\\\\=43.30\ N

So, the required force is 43.30 N.
