Answer:
-√64: rational
15 pi: irrational
46.86 repeated: rational
15/19: rational
-2√6: irrational
Step-by-step explanation:
From the picture that I used, I was able to find out which ones were rational and irrational.
-√64: rational because it equals to -8
15 pi: has "pi" in it
46.86 repeated: as long as it's repeated, it's rational
15/19: fractions are usually rational
-2√6: √6 is cannot be rationalized
Answer:
Step-by-step explanation:
The relation is not a function when x -value is same but y- values are different.

- k^2 - 5k = k + 7
- k^2 - 6k = 7
- k^2 - 6k + 9 = 16
- k - 3 = 4 ⇒ k = 7
- k - 3 = -4 ⇒ k = -1
#3
- k^3 - 5k^2 + 3k = -k
- k^3 - 5k^2 + 4k = 0
- k(k^2 - 5k + 4) = 0
- k = 0, k = 1, k = 4
#4
- |k + 1| + 2 = 8
- |k + 1| = 6
- k = 5, k = -7
In the first 25% of the produce, 7% of that is defective. Which means that 25%*93% is not defective.
=20.75% not defective.
In the second 30% of the produce, 6% is defective Which means that 30%*94%
=28.2% not defective
Now for the 3rd 45% of the produce, 4% is defective which means that
45%*96%
=43.2% not defective.
Added together, 20.75+28.2+43.2=92.15% not defective.
