Answer:
16c + 38d + 48f
Step-by-step explanation:
12c + 36d + 48f + 4c + 2d + 12f
= 16c + 38d + 60f
Answer:
similar....
Step-by-step explanation:
in the diagram it is clearly shown that corresponding angles are congruent and all the sides are in 1/2 ratio
C and D are correct. Look how the letters correspond to each other.
Answer:
the ratio is 3:1
Step-by-step explanation:
Answer:
3rd option
Step-by-step explanation:
The sum to infinity of a geometric sequence is
S = ![\frac{a}{1-r}](https://tex.z-dn.net/?f=%5Cfrac%7Ba%7D%7B1-r%7D)
where a is the first term and r the common ratio
The expression inside the summation is
6 ![(\frac{1}{3}) ^{n-1}](https://tex.z-dn.net/?f=%28%5Cfrac%7B1%7D%7B3%7D%29%20%5E%7Bn-1%7D)
which is in the form of the nth term of a geometric sequence
with a = 6 and r =
, then
S =
← expression required
= ![\frac{6}{\frac{2}{3} }](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B%5Cfrac%7B2%7D%7B3%7D%20%7D)
= 9
