Step-by-step explanation:
To solve the given exercise, you must keep on mind the law of logarithms shown below:
Therefore, by applying the law , you can rewrite the expression given, as following:
You know that:
Then, when you substitute values, you obtain:
Answer:
D
Step-by-step explanation:
Given the quadratic
d = - 16t² + 12t ← subtract d from both sides
- 16t² + 12t - d = 0 ← in standard form
with a = - 16, b = 12, c = - d
Use the quadratic formula to solve for t
t = ( - 12 ± ) / - 32
= ( - 12 ± ) / - 32
= ( - 12 ± ) / - 32
= ( - 12 ± 4) / - 32
= ±
= ±
= ±
→ D
