Use the Unit Circle to find the exact value of the inverse trig function.
Vedmedyk [2.9K]

Answer:

330

Step-by-step explanation:

When we are at 30 degrees on the unit circle, we are at the point (\sqrt3/2, 1/2) so if we go to -30 degrees (330 degrees), we will be at point  (-\sqrt3/2, -1/2).

Note: (cosine, sine)

you can use a calculator if you want. No links please help this is very important i will give you brain thing if its correct
erica [24]

Answer:

Step-by-step explanation:

0.25 x 0.044 = 0.011

a. Changing 0.25 to 25 moves the decimal 2 places to the right, and changing 0.044 to 44 moves the decimal 3 places to the right, so once we solve 25 x 44, we have to move the decimal a total of 5 places to the left.

25 x 44 = 1100, then move the decimal 5 places to the left to get 0.01100...but we don't add the zeros at the end.

b. multiplying 1/4 times 0.044 = 0.044/4 = 0.011

Hope this helps.

The point M(-6, -4) is translated 2 units right. What are the coordinates of the resulting point, M′?
fredd [130]
B) (-4, -4)

When moving to the right you are moving to a more POSITIVE region on the x-axis; meaning, the y-value (vertical axis) does not get affected unless you’re moving up or down.

Remember: (-6, -4)
X = -6
Y = -4

If you move 2 units to the right (x-axis) you go from -6 + 2 which equals -4. And again, you’re not moving up and down so your
y-value stays the same and your new coordinates are (-4, -4)
