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

Below is how you insert a picture
Answer:
you could probably do 10x70 or (7x10) x 10 I hope this helps!
Step-by-step explanation:
Answer:
200 miles were driven
Step-by-step explanation:
We know that 
represents the cost of renting a car
Where m represents the number of miles driven
If we know that the cost was $ 130 then we can equal C(m) to 130 and solve for m.
Idk but I will try
1-2/4=1/4 then you simplify 1/4 into 2/3 and 2/3 simplified into nothing so its
2/3
