Answer:
a and b
Step-by-step explanation:
13
1
A = -10 b = 12 c = -9
x = [-12 +- sq root (144 - 4*-10*-9)] / -20
x = [-12 +- sq root (144 -360)] / -20
x1 = 3/5 + (14.7 i / -20)
x2 = 3/5 - (14.7 i / -20)
Answer:
50
Step-by-step explanation:
Answer: 1875
Step-by-step explanation:
The nth term of a geometric progression is given as:
= ar^n-1
Given a = 3 ; r = 5, the nth term will be:
= ar^n-1
= 3 × 5^n-1
The fifth term will be:
= 3 × 5^n-1
= 3 × 5^5-1
= 3 × 5⁴
= 3 × 625
= 1875
The fifth term is 1875
