Common ratio can be found by dividing the 2nd term by the first
r = 48/6
r = 8
an = a1 * r^(n-1)
n = term to find = 8
a1 = first number = 6
r = common ratio = 8
now we sub
a(8) = 6 * 8^(8-1)
a(8) = 6 * 8^7
a(8) = 6 * 2097152
a(8) = 12582912 <==
Answer:
![\frac{10}{11}](https://tex.z-dn.net/?f=%5Cfrac%7B10%7D%7B11%7D)
Step-by-step explanation:
<u><em>The picture of the question in the attached figure</em></u>
we know that
In the right triangle ABC
----> by SOH (opposite side divided by the hypotenuse)
substitute the given values
![sin(g^o)=\frac{x}{z}](https://tex.z-dn.net/?f=sin%28g%5Eo%29%3D%5Cfrac%7Bx%7D%7Bz%7D)
![sin(g^o)=\frac{10}{11}](https://tex.z-dn.net/?f=sin%28g%5Eo%29%3D%5Cfrac%7B10%7D%7B11%7D)
5 goes with total numbers in the ride
k goes with number of kilometers he has already biked
5-k goes with numbers of kilometers left
and then proces of elimination leaves you with 4 and the last one
