The measure of angle zero is 600°. The point XY corresponding to zero on the unit circle is
Andrej [43]

<u>Answer:</u>

x= -\frac{1}{2}\\\\ y= -\frac{\sqrt{3}}{2}

<u>Step-by-step explanation:</u>

We are given that the measure of angle θ is 600° and we are to fin the point (x, y) corresponding to angle θ on the unit circle,

We know that the x,y coordinates in the unit circle are the cosine and sine ratios, respectively.

θ = 600

1 unit circle= 360°

It means that 600° corresponds to 600° - 360° = 240°.

So, θ =  360° + 240°

180° < 240° < 270° (this tells that the point is in the third quadrant and its coordinates are negative)

240° - 180° = 60° (using the supplementary angles to find the sin and cos)\sin 60^\circ = \frac{\sqrt{3}}{2}\\\\\cos 60^\circ= \frac{1}{2}

Therefore, the x-coordinate is the cos of the given angle while y-coordinate is the sine of the given angle and the coordinates are:

x= -\frac{1}{2}\\\\ y= -\frac{\sqrt{3}}{2}

Joe's dog has a mass of 28,000 grams. What is the mass of Joe's dog in kilograms?
lapo4ka [179]
Joe's dog has a mass of 28 kilograms. If you want to know about the solution, all you need to consider is this example: 1kg = 1000g. Therefore, the 28,000 gram dog is all-in-all 28 kilograms in terms of overall mass.

astraxan [27]

If Maya only has $15 dollars to spend and she buys a notebook for $5.50 then that leaves her with $9.50 and if she has to save $7.75 then that leaves her with $1.75 and since she wants to buy cookies then you have to figure out how many cookies she can get with $1.75 plus the tax but food doesn't have tax so she can buy 7 packages of cookies since there only 25 cents is right on point at $1.75 I hope I answered your question with all the calculating I had to do and the typing I went through to explain it to you !!!!!!!!!!!!!!!!!!!!!!!! now could you please give me a thank you and  hit the brain aster button please and thank you so much

 if you do !!!!!!!
