x^2 -2x + x -2
x^2 -x -2
I will assume the equation is v(t) = $ 25900 (.095)^t
The initial value of the car is at t= 0
25900 (.95)^0 = $25900
when t=13 yrs 25900 (.95)^13 = $ 13295.56~ $13296.
s= square side
then areas ratio becomes:
(s+.1s)(s-.1s) / (s * s) =
s^2 - .01s^2) / s^2
(1- .01)/1 = .99/1 = 99/100
'x' x 1/2 x 3/5 x 3/4 x 5/6 =15
45/240 x = 15
x = 15 * 240/240 =$80
5.75 is 5 and 75/100 5 75/100 = 5 3/4 or 23/4
The top number is the NUMERATOR
the bottom number is the DENOMINATOR
No problem.....multiple answers are always good to see other perspectives and ways to solve....and to keep us all honest!
It will be 8:15
1.75 % annual interest is .0175/12 = .001458333 % monthly (periodic) interest
20 years = 240 periods (months)
FV = 80 000 (future value)
PV = amount to deposit
FV = PV (1+i)^n n= periods (240)
80000 = PV (1.001458333)^240
PV = $ 56,389.42
If it is of the form f(x) = x k
then 18=2k and k= 9
conversely, it COULD be yk = x
then 18k = 2 k = 1/9 but convention would likely make it the FIRST answer k= 9
