Given the:
ln(x + 6) - ln(2x - 1) = 1
Using the logarithm rule:
- ln((x + 6) / (2x - 1)) = 1
- ((x + 6) / (2x - 1)) = E ¹
We know,
- ((x + 6) / (2x - 1)) ≈ 2.72
Simplifying we get,
- x + 6 = 2.72 (2x) - 2.72 (1)
By cross multiplication we get,
Therefore, the value of x is 1.97.
The correct option in the exercise ln (x + 6) - ln (2x - 1) = 1 is alternative "D".
Answer:
so, 
Step-by-step explanation:
Answer:
-2.44
Step-by-step explanation:
Is a right angle triangle
We apply SOHCAHTOA
SOH is sin=Opposite divided by Hypotenuse
CAH is cos=Adjacent divided by Hypotenuse
TOA is tan=Opposite divided by Adjacent
so in this case,cos is the right thing to use
Therefore,x=adjacent
15=Hypotenuse
angle=52°
Cos(52)=x÷15
making x the subject,
x=15cos(52)
x= -2.44
Answer:
0.3
Step-by-step explanation:
By definition: 30% = 30/100 = 0.3
