Answer:
aₙ = 1/2 x aₙ₋₁ n≥2
Step-by-step explanation:
aₙ = 1/2 x aₙ₋₁ n≥2
a₁ = 64
a₂ = 1/2 x 64 = 32
a₃ = 1/2 x 32 = 16
The equation: n - 4 = -15
Now let's solve our equation for n.
n - 4 = -15
Add 4 to both sides.
n = -11
Answer:
(x-5) (x+4)
Step-by-step explanation:
x^2-x-20
What two terms multiply to -20 and add to -1
-5*4 = -20
-5+4 = -1
(x-5) (x+4)
Answer:
0.6 (terminating), 0.5, 0.375
Step-by-step explanation:
I would assume you are wanting these in decimal form. In that case, you would have:
2/3 = 0.6 (terminating)
1/2 = 0.5
3/8 = 0.375
