Answer:

see attached

Step-by-step explanation:

The formula tells you the diameter is 2 times the radius. Pick some values for radius and multiply them by 2 to get the diameter. The graph will be a straight line through the origin with a slope of 2.

(Strictly speaking, the graph should not extend to negative values, as negative values for radius and diameter make no sense in the real world.)

We did not put unit labels (cm, feet, yards, km, light-years, etc.) on the graph axes. For a slope of 2, the graph needs the same units on both axes. They can be whatever units of distance you might choose.

A boat costs $12,250 & decreases in value by 11% per year how much will the boat be worth after 4 years

kirill115 [55]

So it decreases by 11% which means by the next year it's worth 89% of the original price, write 89% like a decimal. then put it to the power of 4 (4 years) and multiply by the original number
.89 ^ 4 * 12250 = 7685.92

Answer:

The choice D.

Step-by-step explanation:

$f(x) = {( \frac{1}{6} })^{x} \\ \\ f(3) = {( \frac{1}{6} })^{3} = \frac{ ({1})^{3} }{( {6})^{3} } = \frac{1}{216}$
