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.

What is BC ?<br><br><br><br> Enter your answer in the box.<br><br> units?
White raven [17]

Answer:

The length of the BC is 25 units .

Step-by-step explanation:

As shown in the diagram

In ΔABC  

∠B = ∠C (As given)

(If the angles are equal than their opposite sides are also equal .)

Thus

AB = BC

As given

AB = 4x + 4

AC = 6x - 14

Thus

4x + 4 = 6x - 14

6x - 4x = 14 + 4

2x = 18

x = \frac{18}{2}

x = 9

Put in the

BC = 2x + 7

     = 2 × 9 + 7

     = 18 + 7

     = 25 units

Therefore the length of the BC is 25 units .

What are the zeros of the quadratic function f(x)=2x^2+8x-3
Nezavi [6.7K]

Answer:

-2 +/-  [(sqrt 88)/ 4]

or

0.35, -4.35 to the nearest hundredth.

Step-by-step explanation:

2x^2 + 8x - 3 = 0

Using the quadratic formula:

x = [ -8 +/- sqrt (8^2 - 4*2*-3) ] / 4

=  -2 +/-  (sqrt 88)/ 4
