PH is calculated by the negative logarithm of the hydrogen concentration in a solution. Therefore, the pH in this case is:
pH = -log (0.0000006)
pH = 6.22
Therefore the correct answer among the choices is the last option, pH of 6 with a color pink.
<u>Answer
</u>
4
<u>Explanation
</u>
AP is a tangent meeting a secant BP at P outside the circle.
(PA)² = (PE)(PB)
PA = 6 and chord BE= 5.
Let PE = x
6² = x(x+5)
36 = x² + 5x
x² + 5x + 2.5² = 36 + 2.5²
(x + 2.5)² = 42.25
(x + 2.5) = √ 42.25 = 6.5
x = 6.5 - 2.5 = 4 or x = -6.5 - 2.5 = -9
But since length cannot be negative, x = 4.
Answer:
x=6
Step-by-step explanation:
LCM of 3,2 : 6
(4/6)x + (3/6)x = 7
(7/6)x =7
(divide 7/6 on both sides)
x= 6
