There are 3 nickels because if you use the ratio 6 to 1 you multiply 6 by 3 to get 18 pennies and you do the same with the one and that’s how I got 3 nickels.
The graph of g is one-fifth as steep as the graph of f.
The function g basically takes the inputs for f and multiplies them by one-fifth, which means the outputs are one-fifth times those of f. Multiplying by one-fifth makes something smaller (it's the same as dividing by five). It helps to visualize this relationship, so I've attache the graphs below.
Shaded area will be the part of the area of the circle which have a central angel = 243
Shaded area = (243/360) π r^2
= (243/360) * 3.14 * 12.5^2
= 331.2
yes because you do the opposite so it would not be a function
