zimovet [89]

Answer:

Without price increase, Cost/night = $119

Average occupancy = 372 The revenue will be 119*372 = $44,268

For every $15 price increase, the occupancy decreases by 25. Therefore with x price increases, The revenue will be $(119 + 15x)*(372 25x)

Cost/night = $119 + 15x Occupancy = 372 - 25x

Answer:

The nightly cost with x $15 price increases is $119 + 15x.

Please help it is 10th grade Equations of lines and circles 7. Michael is hanging out in the park and needs to keep his so
frosja888 [35]

Step-by-step explanation:

1) the required equation in common form is:

(x-x₀)²+(y-y₀)²=r², where (x₀;y₀) - coordinates, where Michael is standing; r - the social distance;

According to the common form and given coordinates (x₀=-5; y₀=2; r=6) it is possible to make up the required equation:

<u>(x+5)²+(y-2)²=6².</u>

2) if the distance between two friends is:

d=\sqrt{(-5-1)^2+(2-1)^2}=\sqrt{37}, \ then

this distance is longer than social (6 ft). For more info see the attachment.

discriminant: tells you about the roots of a quadratic

general form: y = a(x - h)^2 + kstandard form: ax^2 + bx + c = 0root: a solution of an equation

zero: a value that gives you 0 for a function

x-intercept: where the graph crosses the x-axis

y-intercept: where the graph crosses the y-axis

extraneous: a solution that does not work

parabola: the graph of a quadratic

vertex: the turning point of the parabola

axis: line of reflection

translation: movement up/down and left/right of any parabola from standard position (f(x) = x2)

The basics of what you should know
