If the recursive formula is a(n)=a(n-1)+3 and a1=2 then the explicit formula is:
a(n)=2+3(n-1) which simplifies to
a(n)=2+3n-3
a(n)=3n-1 so the first three terms are a(1), a(2), and a(3) which are:
2, 5, and 8
I think the answer is 7. Hope this helps!
Answer:
The measurement of the angle subtended by an arc with a length of 5/2 pi meters is 149.542°
Step-by-step explanation:
Here, the diameter of the circle = 6 m
Diameter = 2 x RADIUS
So, radius = D / 2 = 6 / 2 = 3 m
Also, the length of the arc = (
) meters
Putting π = 3.14, we get
The length S of the arc =
or, S = 7.85 m
Let us assume the arc subtends angle Ф at the center of the circle.
⇒ S = r Ф
or, Ф = 
⇒Ф = 2.61 radians
Now, 1 Radian = 57.2958 Degrees
⇒ 2. 62 Radian = 2.61 x ( 57.2958 Degrees) = 149.542 °
or, Ф = 149.542°
Hence, the measurement of the angle subtended by an arc with a length of 5/2 pi meters is 149.542°

Answer:
Step-by-step explanation:
Remark.
I take it we are only concerned with the deep lime face that we can see closest to us.
Construction
Draw one line that goes from the right of the left foot up to the 18 foot line
Draw another line that goes from the left of the right foot up to the 18 foot line.
label the width of the right foot as 18 - 6 - 6 = 6
Solution
Right foot
Area = L * w
L = 12 feet
w = 6 feet
Area = 12*6 = 72
Left foot (same area) 72
Area above the door.
Height = 12 - 6 = 6
width 6
Area = 6 * 6 = 36
Answer: Total Area = 72 + 72 + 36 = 180
