Im trying to do IXL and I dont understand the way my teacher teaches (ironic right?)

Hoochie [10]

Answer:

r = - 2

Step-by-step explanation:

Calculate the slope m using the slope formula and equate to $\frac{1}{7}$

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (- 9, - 3) and (x₂, y₂ ) = (- 2, r)

m = $\frac{r+3}{-2+9}$ , that is

$\frac{r+3}{7}$ = $\frac{1}{7}$ ( cross- multiply )

7(r + 3) = 7 ( divide both sides by 7 )

r + 3 = 1 ( subtract 3 from both sides )

r = - 2

Find the length of a curve. y=(4-x^2/3)^3/2 from x=1 to x=8

Aneli [31]

$y=\left(4-x^{2/3}\right)^{3/2}\implies y'=\dfrac32\left(4-x^{2/3}\right)^{1/2}\left(-\dfrac23x^{-1/3}\right)=-\dfrac{\left(4-x^{2/3}\right)^{1/2}}{x^{1/3}}$

The arc length is given by

$\displaystyle\int_1^8\sqrt{1+\left(-\dfrac{\left(4-x^{2/3}\right)^{1/2}}{x^{1/3}}\right)^2}\,\mathrm dx=\int_1^8\sqrt{\dfrac4{x^{2/3}}}\,\mathrm dx=\int_1^82x^{-1/3}\,\mathrm dx=9$
