First, we have to find the rate:
500/50
100/10
10/1
10 cents a pitch:
129 * 10 = 1290
It will cost $12.90
Answer:
The slope of the line would be -3/2.
Step-by-step explanation:
Let's get this equation into the proper slope form:
2x - 3y - 5 = 0
2x - 3y + 3y - 5 = 0 + 3y
2x - 5 = 3y
(1/3)(2x - 5) = 3y * 1/3
2/3x - 5/3 = y
Since the slope is 2/3, we need to find the negative reciprocal of that number, which is -3/2.
The mass of substance left after 7 days is 13.09 g
The mass of substance left, N is given by
N = N₀exp(-λt) where λ = decay constant and N₀ = initial mass of substance present = 24 g and t = time
Also, λ = 0.693/t' where t' = half-life of iodine = 8 days
So, λ = 0.693/t'
λ = 0.693/8
λ = 0.086625/day
Since the mass of substance left is N = N₀exp(-λt) and we require the mass of substance after t = 7 days,
N = N₀exp(-λt)
N = 24 gexp(-0.086625/day × 7 days)
N = 24 gexp(-0.606375)
N = 24 g × 0.5453
N = 13.09 g
So, the mass of substance left after 7 days is 13.09 g
