Answer:

28

Step-by-step explanation:

So in this question, we know that n is now 21. So if we substitute n with 21, we get

                                                -2 +\frac{3}{2}(21 -1)

                                               = -2 + \frac{3}{2}(20)

                                               =-2+\frac{60}{2}

                                               =-2 + 30

                                               = 28

Which is our answer.

Answer:

D. log(9)

Step-by-step explanation:

log(9x^{5})+5log(\frac{1}{x})

Remember: A log (x) = log(x^{A})

log(9x^{5})+log((\frac{1}{x})^{5})

Manny has read 113 pages of a 158 page book. If he he reads nine pages a day, how many more days will it take manny to finish th
sashaice [31]
Since 158 minus 113 is 45, Manny only has to read 45 pages. If Manny reads nine pages a day, you have to divide 45 by 9, which leaves you with 5. It will take Manny 5 days to finish the book.

Oksana_A [137]
This is what irrational means:
A number that cannot be expressed as a ratio between two integers and is not an imaginary number. If written in decimal notation, an irrational<span> number would have an infinite number of digits to the right of the decimal point, without repetition.
