Answer:
4a (n-1) + 5
Step-by-step explanation:
1th=6
2nd=29
3rd=121
4th=489
.
.
nth
if n=2
a2 = 4a(2-1) + 5 = 4 a(1) + 5 = 4 (6) + 5= 29
a3 =4a(3-1) + 5 = 4 a(2) + 5 = 4 (29) + 5= 121
try finding a4, check wether the answer is 489
Answer:
4
Step-by-step explanation:
yeah yeah yeah yeah 2+2=4
Divide 15 minutes ÷ 2 1/4 = 6 2/3
divide 25 minutes ÷ 3 3/4 = 6 2/3
They both ran the same amount of time
Izzy ran 6.67 minutes per mile
Julia ran 6.67 minutes per mile
(6.67 is the same as 6 2/3 and i think its mile per minute unless the textbook said it)
Solution:
<u>We know that:</u>
- Diameter = 22 meters
- Radius = Diameter/2
- Area of circle = πr²
<u>Finding the radius:</u>
- Radius = Diameter/2
- => Radius = 22/2
- => Radius = 11 meters
<u>Finding the area of the circle:</u>
- Area of circle = πr²
- => Area of circle = (3.14)(11²)
- => Area of circle = 3.14 x 121
- => Area of circle = 379.94 m²
