Answer:
I don't know how to do this. I'm so sorry that I couldn't help!!
Step-by-step explanation:
sin(x) = 2cos(x)
tan(x) = 2
tan⁻¹[tan(x)] = tan⁻¹(2)
x ≈ 63.4
sin(2x) = sin[2(63.4)]
sin(2x) = sin(126.8)
sin(2x) ≈ 0.801
Answer:
B $10.45
Step-by-step explanation:
Fist you find how much the 2 boxes of cracker cost
$3.50 * 2 = $7
Then subtract the amount of 2 crackers by the $0.80 coupon
$7 - $0.80 = $6.20
Then add that amount to the cost of a jar of peanut butter
$6.20 + $4.85 = $11.05
Then add that about for with the amount of a package of juice boxes
$11.05 + $2.40 = $13.45
Then subtract the total amount to the $3.00 coupon
$13.45 - $3.00 = $10.45
B $10.45 is your answer
