Answer:

I hope this helps you

Step-by-step explanation:

y=x+9

x=y-9 f^-1 (x)= x-9

x=5 f^-1 (5)=5-9 = -4

f (f^-1))=f (-4)=?

x= -4

f (-4)=-4+9

Find the line integral with respect to arc length ∫C(8x+5y)ds, where C is the line segment in the xy-plane with endpoints P=(7,0

puteri [66]

a. Parameterize $C$ by

$\vec r(t)=(1-t)(7,0)+t(0,5)=(7-7t,5t)$

with $0\le t\le1$

b. The integral is to be computed over the range of the parameter $t$ .

c. The integral has a value of

$\displaystyle\int_C(8x+5y)\,\mathrm dS=\int_0^1(8x(t)+5y(t))\|\vec r(t)\|\,\mathrm dt$

$\displaystyle=\int_0^1(8(7-7t)+5(5t))\|(-7,5)\|\,\mathrm dt$

$\displaystyle=\sqrt{74}\int_0^1(56-31t)\,\mathrm dt=\boxed{81\sqrt{\dfrac{37}2}}$
