Which graph shows the solution to the equation below? log3(x+2) = 1

sdas [7]

Refer the attached figure of the graph (Option A) that shows the solution to the given equation

Step-by-step explanation:

The given logarithmic equation is

$\log _{3}(x+2)=1$

The solution to this logarithmic equation is where the graph of

$y=\log _{3}(x+2)$

When comparing above with the given equation, we find that y = 1.

Now, find the 'x' value by using this. So, applying log base 3 rule on right side, we get as below,

$x+2=3^{1}$

x = 3 - 2 = 1

Plot the asymptote and the point (1 , 1). Sketch the log curve using those two reference facts. Hence, concluded the graph in option A as solution to the given equation.

Half-life = [elapsed time * log (2)] / [log (begng amt / endg amt)]
half-life = (3 days * 0.30102999566) / log (1 / .58)
half-life = 0.903089987 / log ( 1.724137931)
half-life = 0.903089987 / 0.23657200643
half-life = 3.8174 days

$\displaystyle |\Omega|=\binom{52}{2}=\dfrac{52!}{2!50!}=\dfrac{51\cdot52}{2}=1326\\ |A|=\binom{4}{2}=\dfrac{4!}{2!2!}=\dfrac{3\cdot4}{2}=6\\\\ P(A)=\dfrac{6}{1326}=\dfrac{1}{221}\approx0.5\%$
