What is the y-value of sin(x) when x = 30°

Mathematics

Sonja [21]3 years ago

The sine of 30° is  0.5 .

Angles don't have y-values, and neither do their sines.  But
IF you draw a graph of the sine function, AND the angles
(the independent variable) are marked off on the x-axis of
the graph, AND the value of the sine function of each angle
(the dependent variable) is marked off on the y-axis of the
graph, THEN the y-value corresponding to the angle of 30°
would be displayed as 0.5 .

Answer:

18

Step-by-step explanation:

cranberries, oranges and lemon extracts makes =96 fluid Ounces of mock-tail

i.e cranberries+oranges+lemon extracts=96 fluid Ounces of mock-tail....... (1)

  • let fluid ounces of orange=x
  • then fluid ounces of cranberry=3x; \\ because it is three times of orange
  • and lemon extract is given as 24 ounces.

putting these values in (1), we get

3x+x+24=96

4x+24=96\\4x=96-24\\4x=72\\x=\frac{72}{4}\\ x=18

fluid Ounces of orange juice was used in all=18

Find the distance between points A and C round to the nearest tenth.
Taya2010 [7]

Well the first thing that came to my mind was to do rise/run and doing that I got 6/5 which I added together to get 11 but since that's obviously not correct I assumed it was a little under so the answer I got was 7.8

Really hope this helps!

(5x – 3y + 8) + (-3x + 6y - 3)​
Wewaii [24]

Answer:

2x+3y+5

Step-by-step explanation:

Firstly, we remove the parenthesis since there is nothing in front of it.

There is a “+” sign in front of the parenthesis, it stays the same.

Secondly, we combine like terms. We combine the x’s, the y’s, and the normal numbers without a variable.

Finally, after combining the like terms. You end up with “2x+3y+5”.
