Answer:
first of all, the formula given is wrong
it is,
so,
let's say
you can choose arbitrarily, answer will be the same
The recursive rule is : a1=8; an=34an-1. The explicit rule for this sequence is 8(3/4)^n-1.
Your answer is: 8(3/4)^n-1

Hello,
f(x)=x-2
g(x)=x²-7x-9
f(g(x))=f(x²-7x-9)=x²-7x-9-2=x²-7x-11
f(g(-1))=(-1)²-7*(-1)-11=1+7-11=-3
Answer B
So the total cost (C) would be equal to the standard charge (S) plus the insurance charge (I). You would plug in the numbers for each into an equation C= S + I.
Unfortunately, I do not understand the numbers given in the equation. There should be a variable for m (the number of miles driven). Although there is an m in the question, the numbers in front of it for the standard charge or insurance do not make sense to me. =I+5.700.25M and
=S+18.950.40M.
Example:
If I was 5.7 + 25m and S was 18.95 + 40m, the equation would look like:
C= S + I
C= 18.95 + 40m + 5.7 + 25m
C= 65m + 24.95
Thanks for asking for my help! Sorry I could not be of more help for you!! :(
If we were to take a cross-section of our planet on the equator, we would get a circle. So, the circumference of this circle is the distance one would have to travel to go around the earth. The formula for the circumference of the circle is 2 x r x pi. The radius of the Earth is r, and pi is approximately 3.1415. So, the circumference is 2 x 6370 x 3.1415, which equals 40 029 km, or approximately 40 thousand kilometers.
