number is described as rational if it can be written as a fraction (one integer divided by another integer). A number is irrational if it cannot be written as a fraction. The decimal form of an irrational number does not terminate or recur.

If the sine of an acute angle is 3/5, what is the cosine of<br> that angle?
Korvikt [17]

Answer:

The cosine of the angle is 4/5.

Step-by-step explanation:

An acute angle is between 0º and 90º, in the first quadrant of the trigonometric circle, in which both the sine and the cosine are positive values.

For each angle \alpha, we have that:

\sin^{2}{\alpha} + \cos^{2}{\alpha} = 1

We have that:

\sin{\alpha} = \frac{3}{5}

So

\sin^{2}{\alpha} + \cos^{2}{\alpha} = 1

(\frac{3}{5})^{2} + \cos^{2}{\alpha} = 1

\cos^{2}{\alpha} = \frac{16}{25}

\cos{\alpha} = \frac{4}{5}

The cosine of the angle is 4/5.

How many units<br> above the x-axis<br> is the point<br> located at (9, 6)?<br> pls help
svetlana [45]

Answer:

6 units above the x-axis

Step-by-step explanation:

The pair (9,6) are a set of coordinates that indicate how far away from the origin (0,0) the point is.

The coordinates are written (x,y) where 'x' is how far to the left or right of the y-axis (vertical) the point is. The 'y' is how far above or below the x-axis (horizontal) the point is.

So in this case, the set of (9,6) means that the point is located at 9 units to the right of the origin and the y-axis and 6 units above the x-axis
