Answer:
n = -18/7
Step-by-step explanation:
Represent the number with n.
Then:
n - 6 = -6(n + 4)
Performing the indicated multiplication, we get:
n - 6 = -6n - 24
Combining like terms results in 7n = -18, so n = -18/7
You didn’t show the graph so i can’t tell what the numbers are so i can’t figure out the slope or y-intercept
Answer:
Initial amount is 523 grams
Amount after 100 years is 52 grams
Step-by-step explanation:
General exponential function for radioactive substances is given by
A(t) = Ao(1/2)^t/t1/2
Where,
A(t) is the amount remaining after t years
Ao is the initial amount of the radioactive substance
t is the number of years required for the radioactive substance to decay to A
t1/2 is the half-life of the radioactive substance
Comparing A(t) = 523(1/2)^t/30 with the general exponential function
Initial amount (Ao) = 523 grams
A(t) = 523(1/2)^t/30
t = 100
A(100) = 523(1/2)^100/30 = 523×0.5^3.333 = 523×0.0992 = 51.8816 = 52 grams (to the nearest gram)
