Answer:

Equation of line in slope-intercept form that passes through (4, -8) and is perpendicular to the graph $y= \frac {2}{5} x - 3$ is below

$y = - \frac {5}{2} x + 2$

Step-by-step explanation:

Slope of the equation $y= \frac{2}{5} x -3$ is $m_1 = \frac{2}{5}$

Since slopes of perpendicular lines are negative reciprocal of each other, therefore slope of other line is given as

$m_2 = - \frac {1}{m_1} = - \frac {5}{2}$

Equation of line in point slope form is given as

$y-y_1=m_2(x-x_1)$

Here (x1, y1) = (4, -8)

$y+8 = - \frac{5}{2} (x-4)$

Simplifying it further

$y = - \frac {5}{2} x + \frac {5}{2} 4 - 8$

$y = - \frac {5}{2} x + 2$

Factor completely x2 + 20x + 99

Bad White [126]

$x^2 + 20x + 99=x^2+9x+11x+99=x(x+9)+11(x+9)=(x+11)(x+9)$

Which statement about the amount of paint found by

stepan [7]

Circumference=37.68cm
2πr=37.68
6.28r=37.68
r=6cm

So

TSA of one hemisphere

2πr²+πr²
6.28(6)²+3.14(6)²
36(6.28)+36(3.14)
36(6.28+3.14)
36(9.42)
339.12cm³

For 2 hemisphere

TSA=2(339.12)=678.24cm³

Step-by-step explanation:

There is really no way to show that of I know of without drawing it but here is this. I hope this helps and not really exact on position but that is very close.
