answer:
$6.65
Step-by-step explanation:
He would earn 21 quarters in 3 weeks.
Because there are 7 days in a week: Multiply 7×3=21
21 quaters in dollars is equal to $5.25
So you add $1.40+$5.25=$6.65
The angle is arctan(3/4) => sin(2t) = sin(2arctan(3/4)) =
2sin(arctan(3/4))cos(arctan(3/4))
Let z = arctan(3/4) => tan(z) = 3/4
2sin(arctan(3/4))cos(arctan(3/4)) = 2sin(z)cos(z) = 2(3/5)(4/5) = 24/25
<span>cos(2t) = cos^2(t) - sin^2(t) = cos^2(z) - sin^2(z) = (4/5)^2 - (3/5)^2 = (16 - 9)/25
= 7/25
