Answer:
tn = 243·(1/3)^(n-1)
Step-by-step explanation:
The recursive formula tells you the first term (243) and the common ratio (1/3). You can put these numbers into the general formula for the n-th term of a geometric sequence:
an = a1·r^(n-1) . . . . . where a1 is the first term and r is the common ratio
You want the n-th term of your sequence to be called tn, so ...
tn = 243·(1/3)^(n-1)
Answer:
C) 50,653
Step-by-step explanation:
y = 1000(3.7)^x
After 3 hours x=3
y = 1000(3.7)^3
y = 1000(50.653)
y =50653
Answer:
Y=10x+25
Step-by-step explanation:
Hey so let’s take the number of hours we go boating as “x” and the TOTAL cost of this whole trip as “y”.
So obviously y would equal everything else so we can write
Y=
Next, it says we rent a canoe for $10 an hour. That means we would have to multiply 10 and x to find the cost of the rent.
So
Y=10x
Finally, it says we paid a registration fee of $25. This 25 is not affected by the number of hours or anything else. It is a fixed amount so we can represent it as
Y=10x+25
Hope this helps!
Answer: y = -10/7 + 8x/7 x = 5/4 + 7y/8
Step-by-step explanation: Move all terms that don't contain y to the right side and solve. Move all terms that don't contain x to the right side and solve.
