Answer:2.75
Step-by-step explanation:
Answer:
<h2>
$65</h2>
Step-by-step explanation:
Step one:
we are told that the ratio of Kailyn's money to Nathan's money is
4:9,
Nathan has $45, let Kailyn's money be x
therefore
4/9=x/45
cross multiply we have
9x=45*4
9x=180
divide both sides by 9
x=180/9
x=20
Kailyn's money is $20
Together they have =20+45= $65
Answer:
θ = πk, 1.318+2πk, 4.965+2πk
Step-by-step explanation:
4sin(2θ) − 2sin(θ) = 0
8sin(θ)cos(θ) - 2sin(θ) = 0
2sin(θ)[4cos(θ)-1] = 0
2sin(θ) = 0
sin(θ) = 0
θ = πk
4cos(θ)-1 = 0
4cos(θ) = 1
cos(θ) = 1/4
θ ≈ 1.318+2πk, 4.965+2πk
Therefore, θ = πk, 1.318+2πk, 4.965+2πk
