Answer:

70.52 degrees

Step-by-step explanation:

To find the angles, we must first find the lengths of each side of the triangle. Adding up the respective radii, we can see that

XY = 5+4 = 9 CM

XZ = 6+5 = 11 CM

ZY = 4+6 = 10 CM

Now we can apply the cosine rule

C\:=\:\sqrt{A^2+B^2-2ABcosx}

We need to rearrange the rule to solve for x, our missing angle

x\:=\:cos^{-1}\left(\frac{a^2+b^2-c^2}{2ab}\right)

solving for our unknown angle:

x\:=\:cos^{-1}\left(\frac{9^2+10^2-11^2}{2\cdot 9\cdot 10}\right)

x\:=\:70.52^{\circ }

Therefore angle YXZ is 70.52 degrees

How to find the average rate of change of a function
ollegr [7]

ANSWER

Average Rate of Change

=  \frac{f(b) - f(a)}{b - a}

EXPLANATION

To find the average rate of change of y=f(x) from x=a to x=b means finding the slope of the secant line joining the points

(a,f(a)) and (b,f(b))

The slope of the secant line joining these points is

=  \frac{f(b) - f(a)}{b - a}

This gives the average rate of change of the function.
