Answer:
Step-by-step explanation:
d=2q, q=d/2
10d+25q=630, using q=d/2
10d+25d/2=630
20d+25d=1260
45d=1260
d=28
So he has 28 dimes.
1) 4c*2
2)a*2
3)c
.........................*=square
Given:
The table of values of an exponential function.
To find:
The function for the given table of values.
Solution:
The general exponential function is:
...(i)
Where, a is the initial value and b is growth factor.
From the given table it is clear that the function passes through the points (1,9) and (2,36). It means the function must be true for these two points.
...(ii)
...(iii)
On dividing (iii) by (ii), we get
Putting
in (ii), we get


Putting
in (i), we get
