Solve the equation = a/4+a/3=21
a=36
1. If
, then
. So
.
2. With
, we differentiate once with respect to
and get
![\dfrac{\mathrm d}{\mathrm dx}[x^2+y^2]=\dfrac{\mathrm d}{\mathrm dx}1](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Cmathrm%20d%7D%7B%5Cmathrm%20dx%7D%5Bx%5E2%2By%5E2%5D%3D%5Cdfrac%7B%5Cmathrm%20d%7D%7B%5Cmathrm%20dx%7D1)


Differentiate again with respect to
and we get


(where
).
3. Check the one-side limits where the pieces are split. For
to be continuous everywhere, we need


In the first case, we have


and
, so it's continuous here.
In the second case, we have


so
is discontinuous at
.
4. If
, then
.
5. If
, then
. So
.
6. The average velocity over [1, 2] is given by

7. If
, then
. So
.
8. If
, then

Differentiating, we get

So
.
9. If
, then
. So 
10. If
, then
. So
.

Answer:
54 miles
Step-by-step explanation:
lets work in steps here:
1 in (24 miles) + 1 in (24 miles) = 2 in OR 48 miles
PLUS
**0.25 in (6 miles)
= 48+6 miles = 54 miles
** you know that 0.25=6 miles because 24/6 is 4. 100/4 is 0.25. simple division.
