Answer:
an = -3·2^(n-1)
Step-by-step explanation:
The first term is a1 = -3.
The common ratio is r = -6/-3 = 2.
The given formula tells you the formula for this sequence is ...
an = -3·2^(n-1)
Answer:
Distance traveled in 6 revolution = 56.52 ft
Step-by-step explanation:
Formula:
Circumference of circle = 2πr
r - Radius of circle
It is given that,
A hula hoop has a three foot diameter.
Diameter = 3 ft
Therefore the radius r = diameter/2 = 3/2 = 1.5 ft
<u>To find the circumference of loop</u>
r = 1.5 ft
Circumference = 2πr = 2 * 3.14 * 1.5 = 9.42 ft
<u>To find the distance traveled in 6 revolution</u>
Distance traveled in one revolution = 9.42 ft
Distance traveled in 6 revolution = 6 * 9.42 = 56.52 ft
Answer:
IS A FACTOR
Step-by-step explanation:
1X120=120
2X60=120
3X40=120
4X30=120
FACTORS 1,2,3,4 30,40,60,120
Answer:
80 or 40 linear feet
Step-by-step explanation:
So the total amount of units for sides is 6. (2 2 1 1)
240 ÷ 6 = 40
So if the river was on the long side it would be 80feet, if the river was on the short side it would be 40feet
