Solving Exponential and Logarithmic Equations In Exercise, solve for x.<br> In x = 3

mixer [17]

Answer:

The solution is:

$x = e^{3} = 20.09$

Step-by-step explanation:

The first step to solve this equation is placing everything with the logarithmicto one side of the equality, and everything without the exponential to the other side. So

$\ln{x} = 3$

It already is in the desired format.

Now, we have that, since e and ln are inverse operations

$e^{\ln{a}} = a$

So, we apply the exponential to both sides of the equality

$e^{\ln{x}} = e^{3}$

$x = e^{3} = 20.09$

If you have to apply 30 n of force on a crowbar to lift an object that weighs 330 n, what is the mechanical advantage of the cro

shutvik [7]

<span>The answer is: 2. 11 Crowbar is a Class A lever Therefore the mechanical advantage of the crowbar can be given by either: MA = Output distance/Input distance OR MA = Output force/Input force Since, the question gives only the force, we can use the second formula. MA = Output force/ Input Force = 330 N / 30 N = 11</span>

Saleh is delivering newspapers for his part-time job. He needs to deliver 30 newspapers and has distributed 10 so far.

Nikolay [14]

He has delivered 33.3% of his papers. Think of it as a fraction 10/30. Now 100% is 30 papers. 1/3 of that, which is our fraction reduced, is where you get 33.3%. If you divide 100 into thirds (100/3), you get the percent.

Answer:

21. D

22. C

Step-by-step explanation:

21. The expansion of the given expression is ...

$\displaystyle -\frac{1}{2}\left(-\frac{3}{2}x+6x+1\right)-3x=\frac{3}{4}x-3x-\frac{1}{2}-3x\\\\=\left(\frac{3}{4}-3-3\right)x-\frac{1}{2}=\boxed{-5\frac{1}{4}x-\frac{1}{2}}$

22. The least likely team to make the championship game is the one with the lowest probability.

3/8 < 1/2 < 2/3 < 4/5

The Bulldogs are least likely to play in the championship game.
