The common ratio  ,  r =  9/5

   a1 * (9/5)⁷ = a8

   125/9 * (9/5)^7 = 850  191/625       

6 and -2     

First period interest (6 months ) = .04/2    periods = 1

second period (6 months )  = .06/2    periods = 1

10000 ( 1+.04/2)¹(1+.06/2)¹   = 10 506 .00  dollars

It's a HORIZONTAL line....    find the point 0, - 3   and   go left and right ....

Here is a Venn diagram

WHen you ask 'or'    for a two subject Venn , you include everyone   (sorry....I got the 'dog' and 'cat' labels backwards....result is the same )

so   13 + 3 + 6 = ____________

By doing the long division:

                    x^2    - 13x -5       R   77

(x-1) |  x^3 -14x^2  +18x +72

           x^3 -x^2

                 -13x^2  + 8x

                 -13x^2 +13x

                             -5x   + 72

                             -5x   +  5

                                        77

= sqrt (4*7   *    15    *  9*3   x³ )

= 6x sqrt  (7*15*3 x)

= 6x sqrt ( 315)    

= 6x sqrt(3² *5*7)

= 18x sqrt (35x )

If x = 2

1 + .5 + 0 + .5 + 1 = 3       

6000 +  6000 * .05 * 2  = ____________

value = 23150 * ( 1 - .013)ⁿ

15000 = 23150(.87)ⁿ

15000/23150   = .87ⁿ

log ( 15000/23150) = n log (.87)        I think you can take it from here, no ?
