The perpendicular line would have a slope of 1/3.
Perpendicular lines have opposite and reciprocal slopes.
To do the opposite, take the original slope (-3) and change the sign (3).
To do the reciprocal, take the slope we changed (3) and flip it as a fraction (1/3).
This gives us a new slope of 1/3.
First arrange the words in order:
AAABNN
so there are 3 A's, 1 B and 2 N's.
If there were no constraints,
Number of permutations = (3+1+2)!/(3!1!2!)=6!/(6*1*2)=720/(6*2)=60
Number of words that begin with B is to take out the B, that leaves us with
AAANN => 3 A's and 2 N's
=> 5!/(3!2!) = 120/(6*2)=10
Therefore the number of words that do NOT begin with B is
60-10 = 50 ways
The answer is : A (-a,0)
It can't be 'b' as it is on y-axis.
So we are left with A.
On the x-axis, y=0. And x is -a as 'a' is a x-coordinate.
Hope it helped!!
To go from exponential to logarithmic, you can use
(exponential) =>
(logarithmic). With your specific equation, this would make
=>
, with that being your logarithmic form.
