log(54)≈3.988984

8/(3 π) + π≈3.9904190

1/2 (e! + 1 + e)≈3.989551

-(sqrt(3) - 3) π≈3.983379

(14 π)/11≈3.9983906

25/(2 π)≈3.978873

(81 π)/64≈3.976078

(2 e^2)/(1 + e)≈3.974446

I need help please.

IgorLugansk [536]

Answer:

13 - 17 $\sqrt{11}$

Step-by-step explanation:

Using the rule

$\sqrt{a}$ × $\sqrt{a}$ = a

Each term in the second factor is multiplied by each term in the first factor, that is

2 $\sqrt{11}$ ( $\sqrt{11}$ - 9 ) + 1 ( $\sqrt{11}$ - 9 )

Distribute both parenthesis

= (2 × 11) - 18 $\sqrt{11}$ + $\sqrt{11}$ - 9

= 22 - 17 $\sqrt{11}$ - 9

= 13 - 17 $\sqrt{11}$

Dimas [21]

Answer:

$57\%$

Step-by-step explanation:

Given: Number of students who were given Cardinal Credits last week for good behavior = 14

Number of students who were given Cardinal Credits this week for good behavior = 22

To find: percent increase in number of students who were given Cardinal Credits

Solution:

Increase in number of students = 22 - 14 = 8

Percent increase in number of students who were given Cardinal Credits = Increase in number of students / Number of students who were given Cardinal Credits last week for good behavior × 100 $=\frac{8}{14}\times 100=57.14\approx 57\%$
