Answer:
sinθ = 5/13
Step-by-step explanation:
cosθ = adjacent/hypotenuse (or you could think of it as x/r)
cosθ = -12/13
adjacent = -12
hypotenuse = 13
opposite = ?
To get the opposite, we use the Pythagorean theorem



Now sub in the numbers:

opposite = 5
Now sinθ = opposite/hypotenuse
so sinθ = 5/13
(6+9)/30=15/30=1/2
The answer is 1/2
Y=-4x + 1/4x is the answer
The answer is 605,761 because when it says difference you must subtract.

Answer:
2.8¢, true
Step-by-step explanation:
The value of copper in a penny is reportedly about ...
(0.95 × 3.11 g)×(1 oz)/(28.35 g)×($0.27/oz) ≈ $0.028
Today, the value of the copper in a pre-1982 penny is about 2.8¢, more than double the value of the penny as legal tender.
The claim is true.
