$\int\limits {\pi y^2} \, dy$

y = 2 + x^6

y - 2 = x^6

x = (y - 2)^1/6

$\pi \int\limits^3_2 {(y - 2)^{1/6}} \, dx$

Well, solving this integral

$\pi \int\limits^3_2 {(y - 2)^{1/6}} \, dx$ = 2,69279

The length of a rectangle is 4 more than twice the width. The perimeter is 74 feet. Find the length and width of the rectangle.

mafiozo [28]

(2*length)+(2*width)=perimeter
length=4+2w
(2(4+2w))+(2(w))=74
74=(8+4w)+(2w)
74=6w+8
66=6w
w=11
length=4+2(11)
l=4+22
l=26

Write in point-slope form an equation of the line that passes through the

QveST [7]

Answer:

$y+6 = - 5(x-4)$

Step-by-step explanation:

With the given information, use the point-slope formula $y-y_1 = m (x-x_1)$ to write the equation of the line. Substitute values for the $m$ , $x_1$ , and $y_1$ to find the answer.

$m$ represents the slope, so substitute -5 in its place. The $x_1$ and $y_1$ represent the x and y values of one point the line intersects, so substitute 4 for $x_1$ and -6 for $y_1$ . This gives the following equation:

$y+6 = - 5(x-4)$
