Answer:
$17,280
Step-by-step explanation:
The model for profit (y), in thousands of dollars, as a function of time (x), in years after 1970 is:
The corresponding value of x in 1978 is:
Estimating the profit (in thousands of dollars) in 1978:
Converting it to dollars:
The estimated profit in 1978 is $17,280.
1) circumference of the first bead = 0.25 in
2) circumference of the second bead = (0.25 + 0.15) in
3) circumference of the third bead = 0.25 + 0.15*2 in
4) circumference of the nth bead = 0.25 + 0.15 * (n -1) in
5) circumference of the 24th bead = 0.25 + 0.15 * (24 - 1) = 3.7 in
6) circumference = 2π*radius => radius = circumference / (2π)
7) radius of the 24th bead = circumference of the 24th bead / (2π)
radius of the 24th bead = 3.7 inches / (2π) = 0.5889 in ≈ 0.59 in
Answer: 0.59 in

Is the correct answer
Direct variation means that x and y will always have the same ratio. The only function that does that is the first one y = 0.3x.
For example: (1, 0.3), (2, 0.6), (3, 0.9)
These are the first three points of the function. The ratios 1/0.3, 2/0.6, and 3/0.9 are all the same when you reduce them.
