Answer: [H+] = 10^-7.2
Step-by-step explanation:
Given that the PH of the solution = 7.2
Using the formula pH = –log[H+]. To get the H+ concentration from the pH, raise both sides by the base of 10. Then we have
10^ -pH = H+. with pH of 7.2,
Thus the answer to this problem is
[H+] = 10^-7.2
Answer:
The last option: 27 times the original volume.
Step-by-step explanation:
The dimensions are tripled so and we are talking volumes so:
The factor of enlargement is 3^3 = 27.
2 x (L + W) = Perimeter
2(L + 16) = 80 Then divide both sides by 2
L + 16 = 40 Then subtract 16 from both sides
L = 24 feet
D. The y-intercept of the function is (0, 5) and e. The function crosses the x-axis twice are true
