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 <==
First you need to convert them to the same unit. 1 cm is 10 mm, so the scale is 5:10. 5*2 is 10, so the scale factor is 2.
Answer:
m=-1
Step-by-step explanation:
2.3-5m=9.8+2.5m
+5m=9.8+5m
2.3=9.8+7.5m
-9.8 -9.8
-7.5=7.5m
/7.5 /7.5
-1=m
