Write an equation for the perpendicular line in slope intercept form (-3,7); y=1/3x-3

y = -3x - 2

Step-by-step explanation:

y=The given line is y = (1/3)x-3.  The slope of a line perpendicular to this one is the negative reciprocal of (1/3), which is -3.

Use the point-slope form of the equation of a straight line, taking the given point (h,k) to be (-3,7):

y - k = m(x - h).  Fill in the given info:

y - 7 = -3(x + 3), or y = -3x - 9 + 7.

Simplifying, we get y = -3x - 2.

47.28 or 47.2857143

step-by-step explanation:

you just divide 331 by 7 and you get that answer. ( i think so tho)

for this case we have that by definition, the surface area of a cylinder is given by:

where:

r: it is the radius of the cylinder

h: it is the height of the cylinder

we can also rewrite it as:

where:

la: it's the lateral area

ba: area of the base
