Average speed would be 7 over 20 why it is because I turned both of the fractions into decimals and then I got 1.75 over 0.5 u would divide and it would give you 3.5 then I turned it back to a fraction multiplying it by a 100 gives us 35 over 100 then you simplify it by dividing both denominator and numerator by 5 would give you 7 over 20
Answer:
9/20
multiplty the numerators
3 x 3 =9
--- --- ---
5 4 ?
multiply the denominators
3 x 3 = 9
--- --- ---
5 x 4 = 20
simplify if needed
9/20 is already in its simplest form
Umm... let's say we got 2 1/4... u would multiply the denominator (4) with the number outside (2) ...which gives you 8 and then add the numerator (1).. and then you get 9. And you don't change the denominator so i would get 9/4.
4 use a calculator 3/.75=4
is a polynomial and thus continuous everywhere and differentiable on any open interval. (second option)
The MVT then guarantees the existence of
such that
![f'(c)=\dfrac{f(2)-f(0)}{2-0}=\dfrac{5-1}2=2](https://tex.z-dn.net/?f=f%27%28c%29%3D%5Cdfrac%7Bf%282%29-f%280%29%7D%7B2-0%7D%3D%5Cdfrac%7B5-1%7D2%3D2)
We have
![f'(x)=6x-4](https://tex.z-dn.net/?f=f%27%28x%29%3D6x-4)
so
![6c-4=2\implies6c=6\implies c=1](https://tex.z-dn.net/?f=6c-4%3D2%5Cimplies6c%3D6%5Cimplies%20c%3D1)
