Answer:
30 hours
Step-by-step explanation:
We can use ratios to solve
5 hours x hours
-------------- = -------------
3 walls 18 walls
Using cross products
5*18 = 3x
Divide each side by 3
5*18/3 = 3x/3
30 =x
Answer:
M(t) = 741·(1/2)^(t/5730)
Step-by-step explanation:
One way to write an exponential function is this:
value at time t = (initial value) · (multiplier over period)^(t/period)
Here, the initial value is given as 741 grams, and the time period is 5730 years. The multiplier over that period is 1/2, since half of the quantity remains after that time. The problem statement tells us that "value at time t" is M(t), so we have ...
M(t) = 741·(1/2)^(t/5730) . . . . . t in years; M(t) in grams
Step-by-step explanation:
let f(x)=y
y=7x-13
y+13=7x
y+13/7=x
f-1(x)=x+13/7
