Step-by-step explanation:
Answer:
a)
A to B 5 routes and B to C 4 routes
<u>Total options:</u>
b)
A to C, 20 ways as above calculation.
C to A, 20 ways as well.
<u>Total options:</u>
c)
A to C, 20 ways
<u>Return to A with different ways:</u>
- (5 - 1)(4 - 1) = 4*3 = 12
<u>Total options:</u>
8×25=200
and
200×23=4600
so 8×25×23=4600
Answer:
if i knew i would have told ya
Step-by-step explanation:
Check the picture below.
now, let's take a peek at that above, DQ = UA and QU = AD, so opposite sides of the polygon are equal.
Now, let's check the slopes of DQ and QU
keeping in mind that perpendicular lines have negative reciprocal slopes, let's notice that the reciprocal of 1/1 is just 1/1 and the negative of that is just -1/1 or -1, so QU has a slope that is really just the negative reciprocal of DQ, those two lines are perpendicular, thus making a 90° angle, and their congruent opposite sides will also make a 90°, that makes QUAD hmmm yeap, you guessed it.
