Answers

Answer 1

Answer: 9/25=
25*4=100 so,9*4=36
9/25=36%

x = 4.545

Step-by-step explanation:

Given the expression

$40=(90^2)/(16) sinxcosx\n\nCross\ multiplying;\n\n16*40 = 90^2 sinxcosx\n\n640 = 90^2 sinxcosx\n\n(640)/(8100) = sinxcosx\n from\ trig\ identity, sin2x = 2sinxcosx\nsinxcosx = sin2x/2\n$

$Hence, \ (640)/(8100) = (sin2x)/(2) \n\n(2*640)/(8100) = sin2x\n \n(1280)/(8100)=sin2x\n \n0.158 = sin2x\n\n2x = sin^(-1) 0.158\n\n2x = 9.09\nx = 9.09/2\nx =4.545$

In how many ways can a teacher arrange 6 students in the front row of a classroom with a total of 20 students?

Answers

This is a combination of 20 studants, 6 to 6:

$C_(2,6)=(20!)/((20-6)!6!)=(20!)/(14!6!)=(20.19.18.17.16.15.14!)/(14!.6.5.4.3.2.1)=38,760 \ ways$
