Ok so to find the ratio just do 12/16 = 3/4. that's your common ratio.
The formula for sum of infinite :
a / (1 - r)
a is the first term and r is the ratio
which is
16 / (1 - (3/4))
which is
16 / (1/4)
16 * 4
which is 64
Answer:
1)5873 x 4=23492
2)5000 x 4=20000
3)800 x 4=3200
4)70 x 4=280
5)3 x 4=12
Step-by-step explanation:
Well idk what the numbers are, but the formula to find the are is 3.14(pi) x r^2
Answer: are we just simplifying?
Step-by-step explanation:
F(5) = -2 * 5 + 1 = -9
the pair is (5, -9)
