PLATO Answer: Geometric sequence with a common ratio of 1.5
Step-by-step explanation:
Answer:
Geometric sequence
Step-by-step explanation:
Since the accidents increase by 5% this represents that the number is increasing exponentially . So the sequence is geometric sequence. The geometric sequence can be represented by: a, ar, ar^2, ar^3...

Answer:
5th term
Step-by-step explanation:
x^2 +3 = 28
Subtract 3 from each side
x^2+3-3 =28-3
x^2 = 25
Take the square root of each side
sqrt(x^2) = sqrt(25)
x = 5
(x could be -5, but there are not usually negative terms in a sequence)
Answer:
The quotient ix 3x - 1.

Step-by-step explanation:
f(m/4)=8(m²/16)-4(m/4)
=m²/2-m
f(-4)=-3(-4)²+5(-4)
=-3(16)-20
=-48-20
=-68
