Step-by-step explanation:
Greetings !
simplify for variable y first
apply exponent rule

Add/subtract the numbers -8+3=5

Apply exponent rule

Thus,

secondly, simplify for the variable x
Apply exponent rule as we made on y


multiply bot the values we get
Hope it helps!
So firstly, we have to find f(x) when x = 8 and x = 0. Plug the two numbers into the x variable of the function to solve for their f(x):

Now that we have their y's, we can use the slope, aka average rate of change, formula, which is
. Using what we have, we can solve it as such:

In short, the average rate of change from x = 0 to x = 8 is 5/21.

Answer: 80°
Step-by-step explanation:
Since, If two secants intersect outside the circle, then the measure of the angle formed is one half of the difference of the measures of the intercepted arcs.
In the given diagram,
Chord VS and chord UT are intersecting externally,
Also, ∠SPT is the angle formed by the intersection of these chords.
Thus, by the above property,
![\frac{1}{2}[m(\widehat{VU})-m(\widehat{ST})]=m\angle SPT](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%5Bm%28%5Cwidehat%7BVU%7D%29-m%28%5Cwidehat%7BST%7D%29%5D%3Dm%5Cangle%20SPT)
![\implies \frac{1}{2}[m(\widehat{VU}) - 20^{\circ}]= 30^{\circ}](https://tex.z-dn.net/?f=%5Cimplies%20%5Cfrac%7B1%7D%7B2%7D%5Bm%28%5Cwidehat%7BVU%7D%29%20-%2020%5E%7B%5Ccirc%7D%5D%3D%2030%5E%7B%5Ccirc%7D)


⇒ Measurement of the arc VU= 80°.
