1 answer:
ella [17]3 years ago
5 0

Answer:

2.96

Step-by-step explanation:

The cosine of an angle is the length of the adjacent side divided by the length of the hypotenuse. In this case:

\cos 65=\dfrac{x}{7}

x=7\cdot \cos 65\approx 2.96

Answer:

<em><u>4th one</u></em> is the right answer.

| x | -2 | 1 | 2 | 3 |

| y | -6 | 3| 6 | 9 |

Step-by-step explanation:

The x and y relationship is in the form y=kx and the graph starts from the origin.

Therefore the graph represents a proportional relationship which holds a equation y=x/3, where k=1/3.

Solve each equation using the quadratic formula. Find the exact solution, then approximate the solution to the nearest hundredth
Mariana [72]

Answer:

n_1=2.72\\n_2=0.61


Step-by-step explanation:

 To solve this problem you  must apply the proccedure shown below:

1. You have that the quadratic formula is:

x=\frac{-b+/-\sqrt{b^{2}-4ac}}{2a}

2. To solve the quadratic equation you must substitute the values. So, you have that:

a=3\\b=-10\\c=5

Then you have:

 x=\frac{-(-10)+/-\sqrt{(-10)^{2}-4(3)(5)}}{2(3)}

3. Therefore, you obtain the following result:

x_1=2.72\\x_2=0.61
