5 0
The radius of a circle is half of the diameter
10.) (6/5)= 1.2
1.2/2=.6
The radius of the circle in question 10 is .6 or 1/2 inch

11.) because x (diameter) is not defined in this problem. We can't solve directly for x, but we know the radius is half of the diameter
so we can say
r= 1/2x

Given f(x)=17-x^2, what is the average rate of change in f(x) over the interval [1, 5]?
Dmitry [639]
\bf slope = {{ m}}= \cfrac{rise}{run} \implies 
\cfrac{{{ f(x_2)}}-{{ f(x_1)}}}{{{ x_2}}-{{ x_1}}}\impliedby 
\begin{array}{llll}
average\ rate\\
of\ change
\end{array}\\\\
-----------------------------\\\\
f(x)=17-x^2\quad 
\begin{cases}
x_1=1\\
x_2=5
\end{cases}\implies \cfrac{f(5)-f(1)}{5-1}
\\\\\\
\cfrac{(17-5^2)-(17-1^2)}{5-1}\implies \cfrac{-8-16}{4}\implies \cfrac{-24}{4}\implies -6
