Step-by-step explanation:
75/60=1.25
90/75=1.2
A given term in a PG =a₁rⁿ⁻¹
Let' calculate the 1st term a₁, knowing a term & the common factor/ratio
a₄ = 1/2 so 1/2 = a₁(1/2)³
1/2 = a₁/8 and a₁ = 4
Now calculate a₉ =a₁.r⁸
a₉ = 4.(1/2)⁸ and a₉ = 1/64
Answer:
Answer: a5 = 2500
Step-by-step explanation:
For a geometric sequence:
First term = a0
Second term = a1 = a0*r
Third term = a2 = a0*r^2
Fourth term = a3 = a0*r^3
....
nth term = a(n-1) = a0*r^(n-1)
Given: a1 = 4 = a0*r
Also: r = 5
So, a0*5 = 4 => a0 = (4/5)
a5 = a(6-1) = Sixth term = a0*r^5 = (4/5)*5^5 = 2500
Hope this helps
correct me if im wrong☺

Answer:
true
Step-by-step explanation:
square root functions are just half of a parabola rotated 90° so depending on which half of the parabola (top has minimum and bottom has maximum) it is, it will have one, but it cannot have both since it is a continuous function after the max or min
