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☺
The fundamental definition of a radian: take a piece of string as long as the radius of a circle, and bend it round the circumference, The angle it subtends at the centre is a radian.
<span>Because you need 2*pi radii to to go all round a circle, it follows that 2*pi radians = 360 degrees; 1 radian = 180/pi degrees. </span>
<span>An arc length L subtends an angle (L/r) radians where r is the radius of the circle.</span>
