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:
(√2)x units
Step-by-step explanation:
x is one leg of another isosceles right triangle whose hypotenuse is the leg of interest. The hypotenuse of an isosceles right triangle is √2 times the leg length, so the leg of the large triangle is ...
(√2)x . . . . units
Answer:
5
Step-by-step explanation:
Put 3 where x is and do the arithmetic.
f(x) = 2x -1
