Answer:
<u>1 gallon / 600 sq ft</u>
Step-by-step explanation:
As we can see, we are given that 600 sq ft uses one gallon to cover, therefore one gallon covers 600 sq ft (just vice versa of what's given).
Answer:
Step-by-step explanation:
- Well I hate to break the news but 243 is not a perfect square. I'll work you through it, 243 is not a perfect square because it is not an even number. an even number must end in (0,2,4,6,8)
- Step one. Find the square root. the square root of 243 is <em>15.588. </em>
- Step two Is it a perfect square. No 243 just cant be a perfect square.
- Hope this helped :)
Answer:
y = - 8
Step-by-step explanation:
The given line passes through (-4, 4) and (4, -2)
The slope of this line will be given by: Change in y ÷ change in x
Slope = = =
The slope of the given line times the slope of the perpendicular line = -1
Let's say the slope of the perpendicular line is p
Then, × p = -1
p = -1 ÷ =
The perpendicular line passes through point (6, 0)
Taking another point (x, y) on the perpendicular line;
=
Cross multiplying this gives the equation of the perpendicular line to be:
y = - 8
By the fundamental theorem of calculus,
Now the arc length over an arbitrary interval
is
But before we compute the integral, first we need to make sure the integrand exists over it.
is undefined if
, so we assume
and for convenience that
. Then
