BRAINLIEST ASAP! PLEASE HELP ME :)
harkovskaia [24]

Answer:

○\displaystyle -\frac{2\sqrt{3}}{3}\:[or\:-\frac{2}{\sqrt{3}}]

Step-by-step explanation:

You have to know the Unit Circle on this one. So, to start off, in the degree-angle range from 180° - 270° [Quadrant III], you must figure out the cosine value that gives you −½, and according to the graph, <em>theta</em><em> </em>will be represented as 240°. So, now that we have our <em>θ</em>, looking at the <em>y-value</em><em> </em>240°, since we want the <em>cosecant</em><em> </em>function, all we have to do is take the multiplicative inverse of \displaystyle -\frac{\sqrt{3}}{2},which gives you \displaystyle -\frac{2\sqrt{3}}{3}.

Extended Information

\displaystyle y-coordinate → sin\:θ \\ x-coordinate → cos\:θ

\displaystyle -\frac{2\sqrt{3}}{3} = [-\frac{\sqrt{3}}{2}]^{-1}

At time t​=0, water begins to drip out of a pipe into an empty bucket. After 48 ​minutes, there are 12 inches of water in the bu
morpeh [17]

Answer:

W = (1/7) t

Step-by-step explanation:

At t = 0, W  =  0

At t = 56 minutes , W = 8 inches

W = k*t    The y intercept = 0 because t = 0 W = 0

8 inches = k * 56 minutes

k = 8 / 56

k = 1/7 inches / minute

W = (1/7) t
