Answer:
72.3
Step-by-step explanation:
Given that:
The arithmetic sequence:
The first term of the sequence = 3 since k = 0
i.e (3 + 0.26(0)) = 3
The last term of the sequence = 6.64
i.e (3+ 0.26(14)
= (3 + 3.64)
= 6.64
Total no of terms = 15 i.e from 0 to 14
∴
The partial sum of the arithmetic sequence =
= 72.3
Answer:
80 square units
536.6
Step-by-step explanation:
First one.
2 Trapezoids
A = x h
A = x 2
A = 16
One rectangle
A = b x h
A = 6 x 8
A = 48
Total Area = 16 + 16 + 48 = 80
Second one:
Two triangles:
A =
A =
A =
A = 43.3
One large rectangle
A = b x h
A = 30 x 15
A = 450
Total Area = 450 + 43.3 + 43.3 = 536.6
