Since a(n)=-3(a(n-1)) the common ratio is -3, and a(1)=-3 so
a(n)=-3(-3^(n-1)) so the first four terms are:
-3, 9, -27, 81
Answer:
B, C
Step-by-step explanation:
Both these intervals are where the graph is increasing.
x=83°
Step-by-step explanation:
In the given figure,
Sum of all angles of triangle = 180°
So, 44° + 53° + x = 180°
97° + x = 180°
x = 180 - 97
x = 83°
Hope helps :D
Answer:
Choice C
Step-by-step explanation:
