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.

Use the graph to determine the y intercept
mafiozo [28]

Answers:

  • y intercept:  9
  • zeros:  -3, -1, 1, 3

===============================================

Explanation:

The y intercept is where the curve crosses the y axis. The curve appears to do so just below y = 10, so y = 9 seems like a good estimate. I'm basing this off of the answer choices given. The y intercept always occurs when x = 0.

The zeros, aka roots or x intercepts, are where the curve crosses or touches the x axis. This occurs in four locations: x = -3, x = -1, x = 1 and x = 3. The x intercepts always occur when y = 0.

What is the value of m so that the two expressions are equivalent?
Law Incorporation [45]

Answer: 0

Step-by-step explanation:

Since m is with x, you don't need to care about y

We would get 2x - 6x + 4x = mx

0x = mx

m is 0
