2 Answers: Choice B and Choice C

====================================================

Explanation:

  • Choice A is false because all of y = 3^x is above the x axis. There are no portions below the x axis, which means it cannot possibly be symmetric about the x axis.
  • Choice B is true. The exponential undoes the log, and vice versa. This only works if the bases of the exponential and log are the same. In this case, both are base 3.
  • Choice C is true. To visually find the inverse, we reflect over the line y = x.
  • Choice D is false. Converting y = 3^x to logarithmic form leads to x = \log_3(y). So you'll need to swap the x and y.

I believe the answer would be the first choice (4 of each color) because of how similar the probabilities are. The table showed that the probabilities are very similar, and this model represents that.

Judy built a rectangular patio that is 9 meters wide and has a perimeter of 40 meters what is the length of Judy’s patio
loris [4]
Hi !

<span><u>Judy built a rectangular patio that is 9 meters wide and has a perimeter of 40 meters what is the length of Judy’s patio ?</u></span>

l=9\;m\\L=x

So\;Perimeter=2(9+x)=18+2x=40\;m\\\\18+2x=40\\2x=40-18\\2x=22\\\\x=\dfrac{22}{2}\\\\\boxed{x=L=11}

The lenght of Judy's Patio is 11 meters.

Determine the solution set of x2 - 80 = 0
meriva

                                         x²  -  80  =  0
Add 80
to each side:                      x²          =  80

Square root
each side:                         x            =  √80

Look it up:                        x  =  + 8.944... (rounded)
                                 and
                                       x  =  - 8.944...  (rounded).
___________________________________

Here's a cleaner solution:

                                         x²  -  80  =  0
Add 80
to each side:                      x²          =  80

Square root
each side:                         x            =  √80

 But  80 = 16 · 5

 So     √80  =  √16 · √5

            √16 = 4, so            x  = 4 √5
