For this case we first write the equation of which we will use:
I (db) = 10log (l / l)
We substitute the value of l.
We have then:
l = 10 ^ 8lo
Substituting in the given equation:
I (db) = 10log ((10 ^ 8lo) / lo)
Rewriting:
I (db) = 10 * log (10 ^ 8)
I (db) = 80
Answer:
I (db) = 80
option 4
Using Quadratic formula,
x = 0.386, -3.886
Answer:
c) 5.39
Step-by-step explanation:
The digit that is in the hundredths place is the 8. (The hundredths are two digits to the right of the point).
The thousandths in this case would be the 9, since the 9 is close to the next hundredth, the nearest hundredth would be 9 (adding 1 to the 8), therefore the number would be 5.39
Answer:
x=2
Step-by-step explanation:
2x=4
x=4/2
x=2
Answer:
35
Step-by-step explanation:
to solve x² + 10, we plug in the given value for x which is 5
solve x² + 10 when x = 5
(5)² + 10 < mulitiply 5²
25 + 10 < add
35
the solution to the equation is 35
