Volume:
Rectangular prism on top of the other rectangular prism:

Length • Height • Width

Substitute

2 • 1 • 6 = 12

Bottom rectangular prism:

Length • Width • Height

Substitute

8 • 4 • 6 = 192

Add

192 + 12 = 204 cm^3

Surface area:

Upside down T: 2((8 • 4)+(2•1)) = 68

Top down part 1: (2 • 6) = 12

Top down part 2: 2(3 • 6) = 36

Side part 1: 2(6 • 4) = 48

Side part 2: 2(6 • 1) = 12

Bottom: 8 • 6 = 48

Add: 68 + 12 + 36 + 48 + 12 + 48 = 224 cm^2

Volume: 204 cm^3

Surface area: 224 cm^2

Write the equation of a line perpendicular to 9xplus7yequals6 that passes through the point (9,negative 7).

andrew11 [14]

$k:\ y=m_1x+b_1\\\\l:\ y=m_2x+b_2\\\\k\ ||\ l\iff m_1=m_2\\\\k\ \perp\ l\iff m_1m_2=-1$

We have:

$k:\ 9x+7y=6\ \ \ |-9x\\\\7y=-9x+6\ \ \ \ |:7\\\\y=-\dfrac{9}{7}x+\dfrac{6}{9}\to m_1=-\dfrac{9}{7}\\\\l:\ y=m_2x+b\\\\l\ \perp\ k\iff-\dfrac{9}{7}m_2=-1\ \ \ \ |\cdot\left(-\dfrac{7}{9}\right)\\\\m_2=\dfrac{7}{9}\to\ l:\ y=\dfrac{7}{9}x+b$
