The summation for n = 19 is usually 190

   this sequence is only 91

190x =91

x = 91/190    so the numbers in the sequence are reduced by this multiplier

\( \sum_{1}^{20} ( 91/190) n = 100.578947368\)           This would be   a₂₀

They won  4 out of (4+3=7)

4/7 * 154 = won games=............ games

     the rest they lost......

2 *  (7x+14)     =   257

x = 16.357

3453.74 = 1187 ( 1 + r/4)^12*4      solve for r

2.90964 = (1+r/4)⁴⁸

log (2.90964) = 48 log (1+r/4)

log (2.90964) / 48 =   log (1+r/4)     

1.0225 = 1 + r/4

r/4 = .0225      r = 9%  annual

7 ( x² - 9 )

7 (x-3)(x+3)

s in this case = 2x from 0 to 3

  should be      s in this case = 2 y from 0 to 3

a)    put '3' in for 't'  in the equation given and calculate the height at 3 sec

b.)   max height will occur at t = -b/2a    where b = 64   and a = -16

          this is the TIME when the apple is at max height

              to calculate THIS HEIGHT , put the t you just found into the equation and calculate max height

c) When the apple becomes applesauce, the height = 0

         so   solve   0 = -16t² + 64 t + 80         use Quadratic Formula or factoring       throw out any negative 't' value     

5 cube sides      5 *   7*7

4 triangles   area = 1/2 b h   =    4   *  1/2 7*8

Add the red equations to get total surface  area in cm²

speed= wavelength * freq

340  = wl * 540

340/540 = wavelength in meters                       (I think)

a₁ = -28       d = -13

a₇₃  =  -28  +  72 (-13) = ...........
