Ratio of  the radii = sqrt16 / sqrt81 = 4/9

so radius of circle Q  is  found by solving  4/9 = 8/x  where x = radius of Q

x = 2*9  = 18

radius of circle Q = 18.

The value of a boat, in dollars, x years after its purchase is represented by the function.
DIA [1.3K]
The average decrease in value can be solve by first solving the value at year 1 and year 2
and i think the equation is <span>f(x)=10,000(0.73)^x</span>

at x = 1

<span>f(x) = 10,000(0.73)^x
</span><span>f(1) = 10,000(0.73)^(1)
f(1) = 7300

at x = 2
</span><span>f(x) = 10,000(0.73)^x
</span><span>f(2) = 10,000(0.73)^(2)
f(2) = 5329

so the average decrease = ( 7300 - 5329) = $ 1971 per year</span><span>
