X³ = 1/8
Take the cube root of both sides.
∛x³ = ∛(1/8)
Since x³ has 3 of such x multiplying each other so we bring out 1 of the x from the cube root sign as discussed.
x = ∛((1/2)*(1/2)*(1/2))
We bring out 1 of the (1/2) out of the cube root sign as well.
x = 1/2
So the answer is the first option. 1 over 2.
I hope this helps.

Answer:
316 lumens/m²
Step-by-step explanation:
We assume your intensity function is ...
f(x) = 50,000(0.975^x) . . . . x meters below the surface
__
Use 200 for x and do the arithmetic.
f(200) = 50,000(0.975^200) ≈ 316 . . . . lumens/m²
Answer:
$13.50 is the tip
OR
$81.01 is total bill
Step-by-step explanation:
total of bill multiplied by 20%
$67.51 x .20 = $13.50
For total bill amount:
$67.51 + $13.50 = $81.01
