Answer:Tn=29-2n
Step-by-step explanation:
Firstly u determine the differences between the terms and see if it's common. These case the common difference is -2 which means these is a linear pattern.
Now Tn=a+(n-1)d
Tn=27+(n-1)(-2)
Tn=27-2n+2
Tn=29-2n
The perimeter of a circle is given by:
P = 2 * π * r where r is the raduis.
Therefore the length of a semicircle is π * r
The radius is therefore
r = 10.28mm / π = 3.272mm
Answer: The height of the pennant is 3 feet.
Step-by-step explanation:
We know that the area of a triangle is given by:-
Given , The base of the triangular pennant is 1.5 feet long.
Area of pennant = 2.25 square feet
Substitute these values in the formula we get,
Hence, the height of the pennant is 3 feet.
