What curve passes through the point (1 ,2) and has an arc length on the interval [2,6] given by Integral from 2 to 6 StartRo

Georgia [21]

Answer:

Step-by-step explanation:

Given

Length of curve

$L=\int_{2}^{6}\sqrt{1+64x^{-6}}dx$

Length of curve is given by

$L=\int_{a}^{b}\sqrt{1+\left ( \frac{\mathrm{d} y}{\mathrm{d} x}\right )^2}dx$ over interval a to b

comparing two we get

$\frac{\mathrm{d} y}{\mathrm{d} x}=8x^{-3}$

$dy=8x^{-3}dx$

integrating

$\int dy=\int 8x^{-3}dx$

$y=-4x^{-2}+C$

Curve Passes through (1,2)

$1=-4+C$

$C=5$

curve is

$y+\frac{4}{x^2}=5$

Help me please . I am stuck

Radda [10]

Answer: n⁴+10n²x+25x²

Step-by-step explanation:

I don;t know how I can use the binomial squares pattern on Brainly, but I can definitely guide you through the problem.

(n²+5x)² [rewrite this from the squared]

(n²+5x)(n²+5x) [use FOIL to expand]

n⁴+5n²x+5n²x+25x² [combine like terms]

n⁴+10n²x+25x²
