Based on the table, Problem A needs to be fixed in 24 hours (9 AM tomorrow). Problem B needs to be fixed in 24 hours (10 AM tomorrow). Problem C needs to be fixed in 12 hours (11 PM that night). Problem D needs to be fixed in 12 hours (11:30 PM that night). So the technician's order will be: C, D, A, B. This is the third choice.

Answer:

4^(11/20)

Step-by-step explanation:

The applicable rule of exponents is ...

(a^b)/(a^c) = a^(b-c)

Using that here, we have ...

4^(3/4)/4^(1/5) = 4^(3/4 -1/5)

= 4^(15/20 -4/20) = 4^(11/20)

Step-by-step explanation:

2x-4=38

-4+4=38+4

2x=42

2x/2=x 42/2= 21

Step-by-step explanation:

Recursive Formula for Arithmetic Sequences

$a_n=a_{n-1}+d$
$a_n$ represents the nth term
$a_{n-1}$ represents the preceding term
$d$ represents the common difference

Explicit Formula for Arithmetic Sequences

$a_n=a_1+(n-1)d$
$a_n$ represents the nth term
$a_1$ represents the 1st term
$d$ represents the common difference

Ernest's Schedule Recursive Formula

We can see that the common difference is $d=0.25$ because for each week, Ernest swims 0.25 more kilometers than the preceding one. Therefore, the recursive formula for Ernest is $a_n=a_{n-1}+0.25$

Ernest's Schedule Explicit Formula

Given our common difference $d=0.25$ from earlier and the fact that $a_1=1$ is our first term, the explicit formula for Ernest is $a_n=1+(n-1)0.25$

Denise's Schedule Recursive Formula

We can see that the common difference is $d=0.5$ because for each week, Denise swims 0.5 more kilometers than the preceding one. Therefore, the recursive formula for Denise is $a_n=a_{n-1}+0.5$
