The formula is:
c= 2 (π)r


steps:
a.) you multiply 2×π (which π=3.14)
b.) so 2×π then multiply the radius ( which is half of the diameter of the circle if your equation doesn't already have the radius listed.)

Which of the following is a solution of 12 x - 7 &gt; 6?<br><br> -1<br> 0<br> 1<br> 2
Mkey [24]

Answer:

The answer to your question is "2"

Step-by-step explanation:

Data

       12x - 7 > 6

Process

1.- Add +7 in both sides of the inequality

       12x - 7 + 7 > 6 + 7

2.- Simplify

       12x >  13

3.- Divide by 12 both sides

         12x/12 > 13/12

                 x > 13/12    or   x >  1.08  

4.- Conclusion

     All the numbers higher than 1.08 are solutions of this inequality

    Then, from the choices, the only possible solution is 2.

VMariaS [17]

Answer:

The answer is No Solutions

Step-by-step explanation:

Since this is absolute value, we know the answer has to be positive, because distance has to be positive. We see it is negative, and that cannot be, so the answer is no solutions.

Is the point 3/5 and 4/5 corresponds to an angle in the unit circle what is the csc
Mariulka [41]

<u>Answer:</u>

csc = 5/4

<u>Step-by-step explanation:</u>

Assuming that the two given points 3/5 and 4/5 are the two sides of a triangle and a right angle 0  with legs x and y and z as its hypotenuse.

Then using Pythagoras Theorem:

z^2=x^2+y^2

z^2=(\frac{3}{5} )^2+(\frac{4}{5} )^2

z^2 = \frac{9}{25} + \frac{16}{25}

z^2=\frac{25}{25}

z^2=1

Taking square root on both the sides:

z=1

Now, sin\alpha=\frac{4}{5}

and we know that csc = \frac{1}{sin\alpha }

Therefore, csc = 5/4.
