A.) If log(2x + 3) -log(x - 1) = 3, then the equation in exponential form is 10^3= (2x + 3)(x - 1).
Tomtit [17]

Step-by-step explanation:

One of the logarithm rules states the following:

log{a} - log{b} = log{\frac{a}{b}}

For this problem, that means the following:

log{2x + 3} - log{x - 1} = log{\frac{2x + 3}{x - 1}}

So now we have the following:

log{\frac{2x + 3}{x - 1}} = 3

Rolling the log, we get the following:

10^{3} = \frac{2x + 3}{x - 1}

Answer:

  • second
  • 3
  • first
  • is

Step-by-step explanation:

We observe that the second equation of System B has had the x-term eliminated. That can be accomplished by adding 3 times the first equation to the second.

"To get System B, the <u> second </u> equation in System A was replaced by the sum of that equation and <u> 3 </u> times the <u> first </u> equation. The solution <u> is </u> the same as the solution to System A."

A boat is spotted in the water with an angle of depression of 25° from the top of a lighthouse that is 89 feet tall. To the near
stepan [7]
To calculate this you need to imagine triangle which points are:
boat
Top of lighthouse
Bottom of lighthouse

That triangle has 90 degrees angle at bottom of lighthouse. That means that we can use trigonometry to determine length between boat and bottom of lighthouse

tan(25) = 89/x
x = 89/tan(25)
x = 190.86

after rounding, the answer is D, 191 feet
