Answer:

x = 0, π/3, π, 5π/3, 2π

Step-by-step explanation:

2sinxcosx = sinx

2sinxcosx - sinx = 0

sinx(2cosx - 1) = 0

sinx = 0, 2cosx-1 = 0

sinx = 0

x = 0, π, 2π

cosx = ½

basic angle = π/3

x = π/3, 2π - π/3 = 5π/3

x = 0, π/3, π, 5π/3, 2π

il63 [147K]

Answer:

bus = 43

van 12

Step-by-step explanation:

This can be solved using simultaneous equations

Let v represent the number of students that a van carries

Let b represent the number of students that a bus carries

the following equations can be derived from the question

3v + 2b = 122 eqn 1

5v + 3b = 189  eqn 2

Multiply eqn 1 by 5 and eqn 2 by 3

15v + 10b = 610  eqn 3

15v + 9b = 567 eqn 4

Subtract equation 4 from 3

b = 43

Substitute for b in equation 1

3v + 2(43) = 122

solve for v

v = 12

Ira Lisetskai [31]

Answer:

0, -2, 2, -1

Step-by-step explanation:

You are trying to make it so that the one of the (  )= 0.

An example is (x+15) or (2x+3)

the first l one would be x= -15 since -15+15 would equal 0.

The second one is -3/2 since it would be -3+3 which would equal 0.

also since the equation starts with x( or -x it doesn't really matter) one of the zeros would also be 0.

Hope this helps!
