GTA V Spankin' New Review!

[Manny Pacquiao N1 Fan]

Here is our review of Grand Theft Auto V. I hope you enjoy this.

 

y = -0.2x² + 12x + 11

y - 11 = -0.2(x² - 60x)

 

complete the square

y - 11 + (-0.2)(-60/2)² = -0.2(x² - 6x + (-60/2)²)

y - 11 - 180 = -0.2(x - 30)²

y - 191 = -0.2(x - 30)²

This is the form of a parabola with vertex (30,191).

 

The x term is squared so the parabola opens either up or down.

a. The -0.2 tells you that the parabola opens down.

=============

Found the problem--misplaced a decimal point.

 

b. -0.2x²+12x + 11 = 0

Use the quadratic formula to solve

ax²+bx+c=0

where

a=-0.2

b=12

c=11

 

x = [-b ± √(b²-4ac)] / (2a)

= [-(12) ± √((12)² - 4(-0.2)(11))] / 2(-0.2)

= [-12 ± √(152.8)] / -0.4

= 30 ± -30.903

 

x₊ = 30 + -30.903 ≅ -1 invalid

x₋ = 30 - -30.903 ≅ 61

 

Ticket sales increase until day 30, then decrease.

 

c. Tickets will stop selling during day 61, so ticket sales start on day 1, and stop 60 days later.

 

d. & e. y' = -0.4x + 12 = 0

-0.4x = -12

x = 30

Min/max occurs on day 30

 

y" = -0.4 < 0 so on day 30 ticket sales peak.

 

f. Ticket sales peak at 191 on day 30.

 

h. The solutions in this case are x=61 and x=-1. A quadratic equation always has two solutions (although the two may be identical).

 

i. x=-1 is an invalid solution because the day can't be negative The graph of a quadratic equation is a parabola, which goes both up and down. Since dTickets/dx=-.4x+12=0 at x=12/.4=30 and the coefficeint on x'2 is negative, the function goes up for x<30 and it goes down for x>30.

 

b. The answer to (a) is the answer here. That is, sales go up for 30 days and down thereafter.

 

c. The largest value of x that solves the quadratic equation

0=-.2x^2+12x+11 is the answer here. That value is

(-12+/-(12^2-4(-.2)(11))^.5)/2(-.2)

=(-12+/-square root(144+8.8)^.5)/-.4

= about 60.90307 days

WHAT THE f*ck IS UP WITH ALL THESE sh*tTY THREADS TODAY, I MEAN REALLY.

Dude, please chill out. You sound like you are on your period.

WHAT THE f*ck IS UP WITH ALL THESE sh*tTY THREADS TODAY, I MEAN REALLY.

Oh, sorry. Here, I have some GTA V Cheats if you want!

 

x^2-10x+y^2-20y=-125 what is x+y=?

 

(Solution)

First complete the square

This is done by taking the x and y term (numbers in front of x and y not x^2 y^2) dividing it by 2 and squaring it and adding it to the other side so you get

x^2-10x+25+y^2-20y+100=0

now break it up

x^2-10x+25=0 and y^2-20y+100=0

trinomial factor it (draw an x put the last number on the top and the middle number on the bottom from each equation) now you want two numbers to put in the side of the x they will be the same number and must multiply to equal the top number and add to be the bottom number so for the x one i used used -5 (-5^2=25 and -5+-5=-10) and for the y i used -10 (-10^2=100 and -10+-10=-20) so those work now to write it in factored from its simply (x-5)^2+(y-10)^2=0 so now just take the opposite of the number in the ( ) for the answers so x=5 and y=10 because (5-5)^2+(10-10)^2=0 and to check you can plug it into the original equation to find that when x=5 and y=10 it will equal -125 as the original equations says so now x+y=5+10 which equals 15 the number you wanted hope that's long enough and i explained my process well enough Start with x = 19 and build up an equation, like this:

 

x + 1 = 20

(x + 1)^2 = 400

(x + 1)^2 + 41 = 441

sqrt[(x + 1)^2 + 41] = 21

sqrt[(x + 1)^2 + 41]/7 = 3

sqrt[(x + 1)^2 + 41]/7 - 2 = 1

log{sqrt[(x + 1)^2 + 41]/7 - 2} = 0

cos((log{sqrt[(x + 1)^2 + 41]/7 - 2})) = 1

Thanks!

 

Here's the list of GTA V Vehicles.

 

Simplifying

4y2 + 8y + -21 = 0

 

Reorder the terms:

-21 + 8y + 4y2 = 0

 

Solving

-21 + 8y + 4y2 = 0

 

Solving for variable 'y'.

 

Begin completing the square. Divide all terms by

4 the coefficient of the squared term:

 

Divide each side by '4'.

-5.25 + 2y + y2 = 0

 

Move the constant term to the right:

 

Add '5.25' to each side of the equation.

-5.25 + 2y + 5.25 + y2 = 0 + 5.25

 

Reorder the terms:

-5.25 + 5.25 + 2y + y2 = 0 + 5.25

 

Combine like terms: -5.25 + 5.25 = 0.00

0.00 + 2y + y2 = 0 + 5.25

2y + y2 = 0 + 5.25

 

Combine like terms: 0 + 5.25 = 5.25

2y + y2 = 5.25

 

The y term is 2y. Take half its coefficient (1).

Square it (1) and add it to both sides.

 

Add '1' to each side of the equation.

2y + 1 + y2 = 5.25 + 1

 

Reorder the terms:

1 + 2y + y2 = 5.25 + 1

 

Combine like terms: 5.25 + 1 = 6.25

1 + 2y + y2 = 6.25

 

Factor a perfect square on the left side:

(y + 1)(y + 1) = 6.25

 

Calculate the square root of the right side: 2.5

 

Break this problem into two subproblems by setting

(y + 1) equal to 2.5 and -2.5.

 

Subproblem 1

y + 1 = 2.5

 

Simplifying

y + 1 = 2.5

 

Reorder the terms:

1 + y = 2.5

 

Solving

1 + y = 2.5

 

Solving for variable 'y'.

 

Move all terms containing y to the left, all other terms to the right.

 

Add '-1' to each side of the equation.

1 + -1 + y = 2.5 + -1

 

Combine like terms: 1 + -1 = 0

0 + y = 2.5 + -1

y = 2.5 + -1

 

Combine like terms: 2.5 + -1 = 1.5

y = 1.5

 

Simplifying

y = 1.5

 

Subproblem 2

y + 1 = -2.5

 

Simplifying

y + 1 = -2.5

 

Reorder the terms:

1 + y = -2.5

 

Solving

1 + y = -2.5

 

Solving for variable 'y'.

 

Move all terms containing y to the left, all other terms to the right.

 

Add '-1' to each side of the equation.

1 + -1 + y = -2.5 + -1

 

Combine like terms: 1 + -1 = 0

0 + y = -2.5 + -1

y = -2.5 + -1

 

Combine like terms: -2.5 + -1 = -3.5

y = -3.5

 

Simplifying

y = -3.5

 

Solution

The solution to the problem is based on the solutions

from the subproblems.

y = {1.5, -3.5}

I want this guy to be my Math teacher

[Kifflom112]

I want this guy to be my Math teacher

This type of math is easy anyways.

Exactly my point.

[_L1pE_]

Hahahahaha, what the hell, why do I find this so funny?

[The Odyssey]

i dont get it

[Kifflom112]

i dont get it

It's just simple algebra, lol. What a dumbass troll.

Yeah, I learned this type of math when I was in 6th grade lol.

[Ryder15]

That made my head hurt... f*ck maths!

[Ex Hellraiser]

 

WHAT THE FUCK IS UP WITH ALL THESE SHITTY THREADS TODAY, I MEAN REALLY.

Fixed that for you.

You shouldn't have dropped out then.

pointless ass math

 

if anyone can tell me a job where i will need this sh*t ill give you a cookie

[Manny Pacquiao N1 Fan]

Thanks everybody.

 

Here is the controls for GTA V:

x^2 + y^2 = z^2

 

xz = y^2

 

x + y + z = 10

Being a math teacher. Where's my goddamn cookie?
