Answer:

Length of the arc will be 2.69 cm.

Step-by-step explanation:

We have to calculate the length of an arc if θ = \frac{2\pi }{7} and radius of arc is 3 cm.

As we know length of an arc = r × θ

By putting the values of angle θ and radius of arc r in the formula

m (arc) =  \frac{2\pi }{7} × 3

           =  \frac{6\pi }{7}

           =  \frac{6(3.14)}{7}

           = 2.69 cm

Therefore, length of the arc will be 2.69 cm.

The first question is D because if the
y-intercept is 1 then every point moves down three units.

The second question is J because a vertical line is not a function so it can’t be a linear function.

Please help with this
Paraphin [41]

Answer:

x = 5

Step-by-step explanation:

The sides are in proportion.

The proportion is 20/36

The other sides must be in the same proportion: 5x / 45

5x/45 = 20/36        You can reduce the left side by dividing top and bottom by 5

1x / 9 = 20/36          You can reduce the right side by dividing by 4

x / 9 = 5/9                at this point you should be able to see that x = 5, because the denominators are the same.

That is the answer.

However you can extend this by cross multiplying

9x = 45                      Divide by 9

x = 45/9

x = 5
