Answer:
The standard form as 
Step-by-step explanation:
Given: A function which is written in vertex form or intercept form.
We have to re-write it in standard form that in terms of
Given 
Squaring using 
, we get,
Multiply 5 inside , we get,
Solving further , we get,
Thus , we have obtained the standard form as
I think the answer is ;B.316 and 38
Answer:
35% of 80 is 28.
Step-by-step explanation:
The pH value of a solution is a logarithmic function of the hydronium ion concentration in the solution. Since we are given the pH foe both we can easily calculate the H+ ion concentration as follows:
Aeen
3.3 = -log (H+)
H+ = 0.04 M
Marien
2.7 = - log (H+)
(H+) = 0.07 M
Therefore, Aeen's drink is 0.07/0.04 or 2 times more hydrogen ion concentration than Marien's drink.
Answer:
Use this pencentage change formula:
New - Old
---------------- x 100
Old
Step-by-step explanation:
390 + 35.10 = 425.1 (New value)
So apply this to the formula:
425.1 - 390
--------------- x 100
390
<em>Which is = 9%</em>
