Answer:
A an = -3 * (1/8) ^ (n-1)
Step-by-step explanation:
We know the first term a1 = -3
And the common ratio r = 1/8 from the an = an-1 * 1/8
The explicit formula is
an = a1 r^ (n-1)
an = -3 * (1/8) ^ (n-1)
Answer:
7.99 m
Step-by-step explanation:
The formula for the circumference (C) of a circle in terms of its radius (r) is ...
C = 2πr
Putting in the given values, we can find r.
50.2 = 2·3.14·r
50.2/6.28 = r ≈ 7.99 . . . . . divide by the coefficient of r; round to 3 significant figures.
To 3 significant figures, the radius is 7.99 meters.
___
Rounded to the nearest tenth meter, it is 8.0 m.
The answer is x=7 is the answer
5%
because 30/100 - 25/100 = 5/100
