Answer:

see explanation

Step-by-step explanation:

given a parabola in standard form : y = ax² + bx + c : a ≠ 0

• If a > 0 then parabola opens up

• If a < 0 then parabola opens down

given y = 4x² - 8x + 8 ← in standard form

with a = 4, b = - 8 and c = 8

here a > 0 then parabola opens up

Perform the indicated operation. 15b/4 * 8/9a^2b^2
Sergio [31]

Answer:

The simplified expression is \frac{10}{3 a^2 b}

Step-by-step explanation:

The given expression is:

\frac{15b}{4} * \frac{8}{9a^2 b^2}

Multiply the items in the numerator together ( 15b * 8 = 120 b). Also multiply the items in the denominator together ( 4 * 9a²b² = 36a²b²). The expression thus becomes:

= \frac{120b}{36 a^2 b^2} \\\\

Divide both the numerator and the denominator by 12b:

= \frac{120b /12b}{36 a^2 b^2/12b}

The expression finally becomes:

= \frac{10}{3 a^2 b}

scoundrel [369]
PH can be calculated using the following equation 
pH = -log [H₃O⁺]
for apple juice the hydronium /hydrogen ion concentration is 0.0003
pH = -log (0.0003)
pH = 3.5
correct answer is C

For ammonia 
pH = -log (3.1 x 10⁻⁹)
pH = 8.5 
answer should be 8.5
