Don't be shy about using actual parentheses and commas.
Line through (1,8) perpendicular to

The perpendicular family is gotten by swapping the coefficients on x and y, negating exactly one of them. The constant is given directly by the point we're through:

Let's clear the fractions by multiplying both sides by 20.

Might as well stop here.
Answer: 25 x + 16 y = 153
V= 735.62
volume formula for sphere is v= 4/3 π r3
the radius is half of the diameter so v= 4/3 π 5.6 3
i think?
Answer:

Step-by-step explanation:

Let's create a table of the values.
