What differentiable functions have an arc length on the interval [a, b] given by the following integrals? Note that the answers

Dafna1 [17]

Answer:

a) $\pm 8\frac{x^{5}}{5}+C$

b) $\pm 4 sin(2x) + C$

Step-by-step explanation:

Given integrals are:

$a) \int\limits^a_b {\sqrt{{1+64x^{8}} } \, dx$ ---(1)

$b) \int\limits^a_b {\sqrt{1+64cos^{2}(2x)} } \, dx$ ---- (2)

Standard form

$L= \int\limits^a_b {\sqrt{1+(f'(x))^{2}} } \, dx$

<h3>Part A</h3>

compare (1) with standard form

$[f'(x)]^{2} = 64x^{8}\\f'(x)=\pm 8x^{4}\\f(x)= \pm8\frac{x^{5}}{5}+C$

<h3>Part B</h3>

Compare (2) with standard form

$[f'(x)]^{2}=64cos^{2}(2x)\\f'(x)= \pm 8cos(2x)\\f(x)=\pm 8\frac{sin(2x)}{2}+C\\f(x)= \pm 4sin(2x)+C$

We are working on equations with variables on both sides..

andriy [413]

Step-by-step explanation:

the equation will be

-4(7+n)=3n

let's solve the equation

-28-4n=3n

add 4n to the both sides

the equation becomes

-28-4n+4n=3n+4n

-28=7n

divide both sides by 7

-4=n

or

n=-4
