Rewrite the expression as a single logarithm and simplify the result.<br> ln lcosxl +lnltanxl
NNADVOKAT [17]
Recall your logarithms rules

\bf ln|cos(x)|+ln|tan(x)|\\\\&#10;-----------------------------\\\\&#10;log_{{  a}}(xy)\implies log_{{  a}}(x)+log_{{  a}}(y)\qquad thus\\\\&#10;-----------------------------\\\\&#10;ln|cos(x)tan(x)|\implies ln\left| cos(x)\cdot \cfrac{sin(x)}{cos(x)} \right|\implies &#10;ln|sin(x)|

What is the greatest common factor of the numerator and denominator of the rational expression below? 5x-20/x^2-2x-8
OleMash [197]
Factories both equations:
5(x - 4) / (x + 2)(x - 4)

Then take out the common brackets:
5 / x + 2

Minus 2 from both sides:
3 / x

If you are looking for the greatest common factor of the numerator and denominator, the answer would be (x - 4)

Janice is 7 years older than Tam. Complete the table, and then graph this situation.
qwelly [4]

Answer:

The table in the exercise can be completed with the next results:

  • x          y
  • 2         <u>9</u>
  • 4         <u>11</u>
  • 6         <u>13</u>
  • 8         <u>15</u>

Step-by-step explanation:

As in the exercise Janice is 7 years older than Tam, to obtain the result in the table, you must add 7 to each age in the column x, with this we can make the next formula:

  • y = x + 7

Remember that x is Tam's age, and y is Janice's age, so, you must replace the x variable in each case to obtain the result to y:

When x is 2:

  • y = 2 + 7
  • <u>y = 9</u>

When x is 4:

  • y = 4 + 7
  • <u>y = 11</u>

When x is 6:

  • y = 6 + 7
  • <u>y = 13</u>

When x is 8:

  • y = 8 + 7
  • <u>y = 15</u>

At last, <u>to obtain the graph you can use the formula made: y = x + 7</u>, and you'll obtain a graph like the attached picture, <em>where each time x obtain a unit, the y variable obtain a unit too maintaining the diference of 7</em>.
