What is the image of (1,0) after a counterclockwise rotation of 60 degrees?
Anestetic [448]

Answer:

\vec s = \left(\frac{1}{2},\frac{\sqrt{3}}{2}  \right)

Step-by-step explanation:

The coordinate has the following polar form:

\vec r = (1, 0^{\circ})

The image of the coordinate rotated counterclockwise 60° is:

\vec s = (1, 60^{\circ})

Its equivalent form in rectangular coordinates is:

\vec s = (1\cdot \cos 60^{\circ}, 1 \cdot \sin 60^{\circ})

\vec s = \left(\frac{1}{2},\frac{\sqrt{3}}{2}  \right)

a group raised $276 for its favorite charity. this is 23% of the amount it hopes to raise. how much money does the group want to
OverLord2011 [107]

Answer: The group wants to raise $1,200.

Step-by-step explanation:

We can use a proportion to solve.

part/whole = percent/100

If we insert the values:

276/x = 23/100

We can cross multiply.

276 x 100 = 27,600

27,600 / 23 = 1,200

$1,200 is the answer.
