Amy can estimate with 10% instead, so she can just simply move the decimal point of $9.11 to the right, and so it will be estimated to more than 91 cents.
it's C, assuming x always has the same value
Answer:
9sqrt(2) ft or 12.73 ft
Step-by-step explanation:
A = L^2
sqrt(162) = 9sqrt(2)
The diagonal of a square is equal to the side length.
Answer:
Initial costs 750 and loses .28 of value each year, so still worth 1-.28=.72 of value at start of next year. 750*(.72)^n is the value after n years since for n=0, new, it is 750*.72^0=750*1=750, and after 1 year it is worth 750*.72^1=750*.72 means it lost 28% value after one year. If you with to express it as an exponential exp(..) you need to convert the .72^n into exp(log(.72)*n)=exp(-.3285*n) so you get
750*exp(-.3285*n) as the value after n years.
Step-by-step explanation:
the answer is (2x+5)(1x+6)
