Answer:
a(n) = 3*3^(n-1).
Step-by-step explanation:
The first term of this sequence is 3. The next one is 3 times 3, or 9; the next is 3 times 9, or 27; and so on. So the common ratio is 3.
The formula for the nth term is thus a(n) = 3*3^(n-1).
Answer: 27.42 ft
Step-by-step explanation:
To find the perimeter first we must find the circumference of the circles.
You can easily find the diameter by subtracting and you get 6.
Using the circle circumference formula c=2piR you get 9.42.
9.42 is our circumference of one circle.
You don't need to divide this by 2 because you already have 2 halves of a circle.
Next add all the sides which is 18.
Add this to the circumference we calculated earlier which gives you 27.42 ft.
12 hours
to calculate time divide distance by average speed
time = = 12.5 = 12
To write this formula in simplest terms, you first need to distribute the negative sign in order to get 10y^8-4y^8-13. Then, since a few of the terms contain y^8, you can combine like terms in order to get 6y^8-13 which is the final answer.
I hope this helps.
Answer:
y=-1/4x-6
It crosses the y axis at -6 and has a slope of 1/4
