Given that Jerry mows 3/20 yards of lawn in 1/6 hour.
Now we have to found how much Jerry can mow per hour.
We know that "work" and "time" are in direct proportion so we can setup the ratio of work and time to easily find the required work.
Hence final answer is yards.
Given:
Y-intercept of exponential function is 8.
It contains the point (3,64).
To find:
The exponential function that describes the graph.
Solution:
The general form of an exponential function is
...(i)
where, a is initial value or y-intercept and b is growth factor.
Since, y-intercept is 8, therefore, a=8.
Put a=8 in (i).
...(ii)
It contains the point (3,64). Put x=3 and y=64.
Divide both sides by 8.
On comparing both sides, we get
Put b=2 in (ii).
The functions form of this equation is
Therefore, the required function is .
