(1/2)[logb(b^2)+logb(8x)]
=(1/2)[2+logb(8x)]
=1+(1/2)logb(8x)
hope this helps you
We let y equal to the elevation above sea level so that the elevation of the rock climber after x minutes of climbing would be:
y = 2x + 50
His initial height can be calculated when x is equal to zero it is when the climber is not yet climbing. Therefore, the rock climber'sinitial height above sea level would be 50 meters.
<h2>
The required "option D. 9.6" is correct.</h2>
Step-by-step explanation:
In given figure,
AD = x, DB = 12, BE = 8 and EC = 10
To find, the value of x = ?
Use the Side-Splitting Theorem,
We know that,

⇒ 
⇒ x =
⇒ x = 
⇒ x = 9.6
∴ The value of x = 9.6
Thus, the required "option D. 9.6" is correct.
