Solve each equation. Show all your work. Round your answers to four decimal places. (a) 7^4x=10,(b)ln(2)+In(4x-1)=5
KengaRu [80]
A.) 7^4x = 10
log base 10 (7^4X) = log base 10 (10)
4x log base 10 (7) = 1
4x (0.8451) = 1
3.3804x = 1
x = 0.2958

b.) ln(2) + ln(4x-1) = 5
ln (2 * 4x-1) = 5
ln (8x-2) = 5
log base (3) (8x-2) = 5
e^5 = 8x-2
e^5+2 = 8x
x = 18.8016

Which of the following is an even function?
12345 [234]

Answer:

  • B. g(x) = 2x² + 1

Step-by-step explanation:

<u>Even function has following property:</u>

  • g(x) = g(-x)

<u>It is easy to show this works with the second choice only. All the others don't work:</u>

  • g(x) = (x - 1)² + 1
  • g(-x) = (-x - 1)² + 1

This is not correct as x - 1 ≠ -x - 1 so as their squares, so g(x) ≠ g(-x)

The last two choices are not even similarly.
