Plot the following radian measures on the given unit circle
son4ous [18]

By our very goofy system the circle constant \pi denotes half a circle, 180^\circ. So the conversion factor from radians to degrees is


\dfrac{ 180^\circ}{\pi}


\dfrac{\pi}{3} \times \dfrac{ 180^\circ}{\pi} = 60 ^\circ


Calling the rightmost dot [1] and counting counterclockwise, that's dot [4].


\dfrac{2\pi}{3}  \times \dfrac{ 180^\circ}{\pi} = \dfrac{2}{3} \times 180^\circ = 120^\circ


That's dot [6]


\dfrac{4\pi}{3} \times \dfrac{ 180^\circ}{\pi} = \dfrac{4}{3} \times 180^\circ = 240^\circ


That's dot [12]


\dfrac{5\pi}{3} \times \dfrac{ 180^\circ}{\pi} = \dfrac{5}{3} \times 180^\circ = 300^\circ


That's dot [14]

one positive number is 28 less than another number. if the reciprocal of the smaller number is added to four times the reciproca
marishachu [46]
Let x represent the larger number.
  1/(x -28) +4/x = 1/6
Multiplying by the product of denominators, we have
  6x +24(x -28) = x(x -28)
In standard form, this is
  x^2 -58x +672 = 0
  (x -42)(x -16) = 0

The two numbers are (-12 and 16) or (14 and 42).

Brooklyn and her friends went into a grocery store and they want to buy some apples and peaches. Each apple costs $1.75 and each
Sphinxa [80]

Answer:

A. $11.75

B. $1.75x + $1.00y = c (cost)

Step-by-step explanation:

A. Because apples cost $1.75 each you could multiply the amount of apples you intent to buy by $1.75 which in this case the amount of apples wanted is  3. $1.75 x 5 = $8.75. You would do the same thing for the peaches except the amount per peach is different. $1.00 x 3 = $3. Then you would add the two amounts together to get the amount Brooklyn and her friend would have to pay. $8.75 + $3 = 11.75

B. Because you multiply the amount of items you intend to get by the cost per item the equation you would follow if the amount of items changed would be. $1.75x + $1.00y = c (cost)

Hope this helps!

Please tell me if I am incorrect I enjoy learning from my mistakes!

Good luck!!
