Answer:
3
Step-by-step explanation:
As we move from A(2, 1) to B(5, 1), x increases by 3 but y stays the same.
Thus, the distance from A to B is simply 3. This is the desired length.
<span>Let x = dollar increase in price
Let y = fewer number of pairs sold
Since 2 fewer shoes are sold for each 1 dollar (factor of 2)
y = 2x
Revenue = Number of shoes sold * Price charged per shoe
Number of shoes sold = 200 - y = 200 - 2x
Price charged per shoe = $60 + $x
Revenue = (200 - 2x)(60 + x) = -2x^2 + 200x - 120x + 12000
Revenue = -2x^2 + 80x + 12000
In a quadratic equation, Revenue is maximized when x = -b / 2a. In this case:
x - -80 / (2*-2) = $20
Price charged per show = $60 + $x = $60 + $20 = $80.
Maximum revenue = -2x^2 + 80x + 12000 (evaluated at x = $20)
Maximum revenue = -2(20^2) + 80*20 + 12000 = $12800</span>
Answer: The rate of change of momentum of a body over time is directly proportional to the force applied and occurs in the same direction as the applied force.
We can write the law as:
Where F is a force, and P is the momentum.
Remember that the momentum is defined as the quantity of motion, such that:
P = M*V
Where M is the mass of the moving object and V is the velocity of the moving object.
Or we can write the second law as:
F = M*a
M = mass
a = acceleration
