C  = 1263n^2   + 1301  

C  =  1263 ( 254)^2  + 1301  =   $ 81,485,009

The  nth term of the sequence  is given by :

(n) (n + 1) (n + 2)  / 2      

oh I get it

but that one woud obviously better said aloud

We need to find the length of one  leg , l,  of the right triangle

So we have

2l^2   =  32      divide by 2

l^2  =  16

l = 4

So.....the surface area of the right triangle  =  (1/2) l^2   =  (1/2)4^2  

And the total surface area  =

Surface area of top/bottom  +  surface area of the sides  =

2 [ (1/2)4^2 ]   +   6 [ 4 + 4 + √32  ]  ≈  97.9  cm^2

We need to solve this

1500 = -475t+2650   subtract 2650 from both sides

-1150  =  -475t        divide both sides by -475

t  ≈  2.42 hrs  =   2 hrs, 25 min

Distance  / Rate  = Time

7.2 / 2.88  =   2.5 hours

Hi. Whats is d equal to in 2.4=2(d)^-2

2.4 = 2/d^2 multiply both sides by 10

24 = 20/d^2

d^2 =20/24 =5/6  take the square root of both sides

d =+or- sqrt(5/6)

why was six afraid of seven, cause seven eight nine gotddem

V = pi·r²·h

                                                             1089pi  =  pi·r²·9

Divide both sides by pi:                        1089  =  r²·9

Divide both sides by 9:                           121  =  r²

Find the square root of both sides:          11  =  r

For  f(x)  =  -4x² - 3x + 2     a = -4     b = -3     c = 2

The quadratic formula is:  x  = [ -b +/- sqrt( b² - 4·a·c ) ] / [2·a]

Substituting:                       x  =  [ - -3 +/- sqrt( (-3)² - 4·(-4)·(2) ) ] / [2·(-4)]

                                            x  =  [ 3 +/- sqrt( 9 + 32 ) / ( -8 )

                                            x  =  [ 3 +/- sqrt( 41 ) ] / -8

                                            x  =  [ -3 +/- sqrt( 41 ) ] / 8

Two-thirds of the grade has been determined; it is 3.6.

If you get a 5 on the final one-third of the grade, you can calculate your final grade by:

     ( 2x3.6 + 5 ) / 3  =  ( 7.2 + 5 ) / 3  =  12.2 / 3  =  4.07

i have found the answer thank u

A parabola is the graph of a quadratic function.

idk its too hard for me :P
