The answer is C, 45 in^2. 6 times 9 is 54, and the unshaded area has an area of 3 times 3, so 9. Subtract the 9 from the 54 and you get 45.

Find the average rate of change of each function on the interval specified.

ExtremeBDS [4]

The average rate of change (AROC) of a function f(x) on an interval [a, b] is equal to the slope of the secant line to the graph of f(x) that passes through (a, f(a)) and (b, f(b)), a.k.a. the difference quotient given by

$f_{\mathrm{AROC}[a,b]} = \dfrac{f(b)-f(a)}{b-a}$

So for f(x) = x² on [1, 5], the AROC of f is

$f_{\mathrm{AROC}[1,5]} = \dfrac{5^2-1^2}{5-1} = \dfrac{24}4 = \boxed{6}$

Answer:

A. XY

Step-by-step explanation:

A chord has both ends on the circle. Point X is not on the circle so segment XY is not a chord.

Please answer question

sweet-ann [11.9K]

Given;

ABCDE is similar to VWXYZ

so, the corresponding segments are proportional

We need to find the length of XY

XY is corresponding to CD

CD = 1.2 cm

Finding another two corresponding sides

DE = 3.2 cm , YZ = 4 cm

so,

$\begin{gathered} \frac{XY}{CD}=\frac{YZ}{DE} \\ \\ \frac{XY}{1.2}=\frac{4}{3.2} \\ \\ XY=\frac{4}{3.2}\cdot1.2=1.5\operatorname{cm} \end{gathered}$

So, the length of XY = 1.5 cm
