A football team plays in a large stadium. With a ticket price of $19, the average attendance at recent games has been 50 comma

tino4ka555 [31]

Answer:

Part 1: N(x) = 50,000 - 300(x-19)

Part 2: R(x) =-300x² + 55700x

Step-by-step explanation:

Given,

The original price of each ticket = $ 19,

The original attendance = 50,000

Part 1 :

∵ For the each $1 increase in the ticket price, attendance decreases by 300.

Let x represents the price of each ticket after increment,

Thus, if price increment = (x-19) dollars,

New attendance, N(x) = 50,000 - 300(x-19)

Part 2 :

Since, revenue = price of each ticket × attendance

Thus, the revenue from the football game,

R(x) = x(50,000 - 300(x-19))

R(x) = 50000x - 300x²+ 5700x

⇒ R(x) =-300x² + 55700x

If f(x) = 3x^2 - 4 and g(x) = x+2, find (f - g)(x).

galina1969 [7]

Answer:

3x^2-x-6

Step-by-step explanation:

f(x) = 3x^2 - 4

g(x) = x+2

(f - g)(x)= 3x^2 - 4-( x+2)

Distribute the minus sign

(f - g)(x)= 3x^2 - 4- x-2

Combine like terms

= 3x^2-x-6

Solve for t. t + 19 = 45) it will give u 29 points if u help me!

Oksi-84 [34.3K]

Hi there!

Answer:

t=26

*The answer must have a positive sign.*

Step-by-step explanation:

First, you subtract by 19 from both sides of an equation.

$t+19-19=45-19$

Then, you subtract by the numbers from left too right.

$45-19=26$

Final answer is t=26

I hope this helps you!

Have a nice day! :)

PLEASE HELP What is the equation in standard form of a parabola with a focus of (-3,2) and a directrix of y=4.

Angelina_Jolie [31]

Graphing y = 4 and the focus, we clearly see that the equation we need has the form (x - h)^2 = 4a(y - k).

We need to find a, h and k.

The focus is half way between the vertex and directrix.

You know that y = 4 is 2 units away from the focus and the focus is 2 units down from the focus. So, our vertex is (-3, 0).

From the vertex to the directrix, there are 4 units. Half that distance is the value of a. So, a = 2.

We have all that is needed to form our equation.

(x - (-3))^2 = 4(2)(y - 0)

(x + 3)^2 = 8y

Done.
