Suppose you save $10 one month and that each month thereafter you save 50 cents more than the preceding month. how much will you have saved by the end of 14 years

  $8694.00

Step-by-step explanation:

The series of savings amounts will have 12×14 = 168 terms. The last amount added to the savings account will be ...

  10 + 0.50(168 -1) = 93.50

So, the average amount added is the average of the first and last amounts:

  (10 + 93.50)/2 = 51.75

That multiplied by the number of terms in the series, 168, will give the total amount added to the savings account:

  168 × $51.75 = $8694.00

By the end of 14 years, you have saved $8694.00.

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
