Answer:
pOH = 9.4
Step-by-step explanation:
Mathematically;
pH + pOH = 14
pOH = 14 - pH
But pH = -log[H3O+]
From the question [H3O+] = 2.5 * 10^-5
Thus pH = -log (2.5 * 10^-5)
pH = 4.6
Thus;
pOH = 14-4.6
pOH = 9.4
Answer:
x = 24
y = 10
z = 17
Explanation:
It's long to explain, so heres a picture of how solved each. hope this helps!! :)
It took 22 $20 bills . $86 x5= $430
Then $430 divide by 20 = 21.5
So you can’t have half a bill do the answer has to be rounded up to 22 twenty dollar bills
Answer:
v=9i+3j
Step-by-step explanation:
The given vector, v has initial point at P1 = (−5, −2) and terminal point at P2 = (4, 1).
The vector v is found by subtraction the initial point from the terminal point.
v=<4,1>-<-5,-2>
v=<4--5,1--2>
v=<9,3>
We write v as multiples of the basis vectors to obtain:
v=9i+3j
