PLEASE HELP!!! I JUST NEED A STEP-BY-STEP!!!!!!

Naya [18.7K]

Answer:

Step-by-step explanation:

$=5\displaystyle\int_{0}^{\pi/6}dx\displaystyle\int_{0}^{2}x\sec^2(xy)dy\\=5\displaystyle\int_{0}^{\pi/6}dx\displaystyle\int_{0}^{2}\sec^2(xy)d(xy)\\=5\displaystyle\int_{0}^{\pi/6}dx\tan(xy)|_{y=0}^{y=2}$

$=5\displaystyle\int_{0}^{\pi/6}\tan(2x)dx\\=-\frac{5}{2}\ln\cos(2x)|_{0}^{\pi/6}\\=-\frac{5}{2}[\ln\cos(\pi/3) - \ln\cos(0)]\\$

$=-\frac{5}{2}\ln{\frac{1}{2}$

What is the slope? What is the y-intercept? What is the equation of the line (slope intercept form?)

yawa3891 [41]

Answer:

The slope is: m = -²/₅

The y-intercept is: b = -2

The equation of the line: y = -²/₅x - 2

Step-by-step explanation:

The equation of a line in slope intercept form: y = mx + b

The slope: $m=\dfrac{y_2-y_1}{x_2-x_1}$

(-5, 0) ⇒ x₁ = -5, y₁ = 0

(0, -2) ⇒ x₂ = 0, y₂ = -2

So:

$m=\dfrac{-2-0}{0-(-5)}=-\dfrac25$
