Solution:
Coordinates of point A = (2,6)
Coordinates of Point B = (18,12)
Let the point P(x,y) divides AB in the ratio of 2:3.
So, formula for internal division
x =
y =
x=
The coordinates of point which divides AB in the ratio of 2:3 is <u>.</u>
POH is the -log [ OH- ]. Using this equation, simply find the -log of the OH- concentration to find the pOH:
pOH = - log ( 0.000086 ) = 4.07
Answer:
15r²-14r-8
Step-by-step explanation:
Use FOIL for this:
(5r+2)(3r-4)
First: 5r × 3r = 15r²
Outer: 5r × (-4) = -20r
Inner: 2 × 3r = 6r
Last: 2 × (-4) = -8
15r²-20r+6r-8=
15r²-14r-8
Answer:
19
Step-by-step explanation:
9+1=10
9*1=9
10+9=19
Start by multiplying six by 3 and getting 18. thendivide 23.15 by 18 = 1.2861111
that's the answer.
