Think: (4)^3 * (x^2)^3, or 64 * x^(2*3), or 64 x^5 (answer)
Tax = 6.25% of $550 = 0.0625 × $550 = $34.375, which rounds to $34.38
I disagree that tax is rounded to the nearest penny. Tax is always rounded up.
Suppose the speed that they paddled was x mi/h
speed of current was 3 mi/h
speed of moving upstream
(x-3) mi/h
speed of moving downstream
(x+3) mi/h
one way distance=24/2=12 miles
time taken to move up stream:
12/(x-3) hr
time taken to move downstream
12/(x+3) hr
total time they paddled:
(8:30 a.m -4:00 p.m)-(1:30)
=7.5-1.5
=7 hours
thus
12/(x-3)+12/(x+3)=7
solving for x we get:
=24x/(x-3)(x+3)
24x/(x^2-9)=7
thus
x=5.1695~5.2 hours
x=5.2 mi/hr
thus
time taken to paddle downstream:
12/(5.2-3)
=5 5/11 hours
=5 3/11 hours
=5 hours 27 minutes
~5 hours 25 minutes
To compute the slope of a segment, given its endpoints 
, you write
Given this formula, you have the four slopes:
Now, two segments are parallel if they have the same slope. So, AB and CD are parallel, because they both have slope 1, but BC and DA are not parallel.
This means that ABCD is not a parallelogram, because in parallelograms the opposite sides are parallel.
