Answer:
E
Step-by-step explanation:
The general term matches the form ...
an = a1 +d(n -1)
for a1 = 7 and d = 3.
This is the form for the general term of an arithmetic sequence with first term 7 and each successive term 3 more than the previous one.
That description matches the recursive formula ...
a(1) = 7; a(n) = a(n-1) +3 . . . . . choice E
-37/6
b = 3/4
The area of a triangle is given by
A = 1/2 bh
3/ 40 = 1/2 b ( 1/5)
Multiply
3/40 = 1/10 b
Multiply each side by 10
10 *3/40 = 10* 1/10 b
3/4 = b
