Answer:
4 hours
Step-by-step explanation:
Since we know he travels at a rate of 1:7.5 all we have to do is divide 7.5 by 30. Do you use proportions? You can set this up as a proportion and the find answer easily.
1
Now we cross product.
7.5 multipled by x =7.5x
1x30=30
so now we have
7.5x=30
Now we have to divide 7.5 on both sides which gives us
x=4
Answer:
The multiplicative rate of change is 0.5.
Step-by-step explanation:
The given function is
.... (1)
It is given that the curve is passing through (0,10), (1,5) and (2,2.5).
The exponential function is defined as
.... (2)
Where, a is initial value and b is growth factor of multiplicative rate of change.
On comparing (1) and (2), we get
Therefore the multiplicative rate of change is 0.5.
