Answer:
2048
Step-by-step explanation:
Time to use recursive formula :)
Since a of 1 = 4 and -the recursive formula is
-2(a of n-1) We know that the r = -2
Convert that to explicit is
f(n) = -2 * 4^n-1
Let's use that to get the value for a of 6.
f(6) = -2 * 4^6-1
= -2 * 4^5
= -2048
Answer:
Diego
Step-by-step explanation:
divide 132 minutes by 44 pages and you get 3 pages per minute, then divide 140 minutes by 35 pages and you will get 4 pages per minute. so Diego reads 1 more page a minute than lin. hope i helped you :)
This is the answer that i found (x4-81) hope it helps have a great day!
Given, the rate of growth of St. Augustine grass is cm per week.
We have to find the number of weeks that the grass grow to cm.
Let's take the number of weeks be x.
In 1 week the grass grow = cm
So in x weeks the grass grow = cm
So we can write,
To solve it for x, first we will move 7 to the right side by multiplying it to both sides. We will get,
Now to get we will move 4 to the right side by dividing it to both sides. We will get,
So we have got the required answer.
After 3 weeks the grass grow .
