Answer:

Th final equation is $Y = 2X^2 -3$

The graph is attached

Step-by-step explanation:

Given

$X = \sqrt{t} \\t = X^2$ --- Eq (1)

and $Y = 2t -3$ --- Eq (2)

Substituting the value of "t" from Eq (1) into Eq (2), we get -

$Y = 2X^2 -3$

The graph for the equation is attached here with

Answer:

x^2+x-2

this is the answer bc the 2nd parentheses is being multiplied by the negative sign meaning you need to subtract it from the 1st parentheses.

The amphitheater has two types of tickets available, reserved seats and lawn seats. The maximum capacity of the venue is 20,000

Tema [17]

Let the number of reserved tickets = x

Let the number of lawn seats = y

Constraint functions:

Maximum capacity means $x+y\leq 20000$

For concert to be held $x+y\geq 5000$

$lawn seats\leq reserved$ means $y\leq x$

Objective functions :

Maximum profit equation p = 65x +40y

Intersection points :

(10000,10000) (20000,0)(2500,2500)(5000,0)

p at (10000,10000) = 65(10000) + 40(10000) = $1050000

p at (20000,0) = 65(20000) + 40(0) = $1300000

p at (2500,2500) = 65(2500) + 40(2500) = $262500

p at (5000,0) = 65(5000) + 40(0) = $325000

Hence maximum profit occurs when all 20000 reserved seats are sold and the profit is $1300000

Please find attached the graph of it.

Which relation is a function?

IceJOKER [234]

Answer:

The bottom right option

Step-by-step explanation:

Functions need each input to map to exactly one output. Graphically speaking, this means that any two points on the function cannot have the same x-coordinate.

Given this, the bottom right option is the only one that fits these circumstances.
