4 dimes=4 *10=40 cents

2.25-0.40=1.85

185=5 times number of nickels
divide both sides by 5
37=number of nickles

Find the equation of the exponential function represented by the table below:
Allisa [31]

Answer:

  y = 0.1(4^x)

Step-by-step explanation:

An exponential function can be written as ...

  y = a(b^x)

where 'a' is the y-intercept, and 'b' is the ratio of terms with consecutive x-values.

The table tells us a=0.1, and b=0.4/0.1 = 4. The equation is ...

  y = 0.1(4^x)
