Answer:
C = 75.36
A = 452.16
Step-by-step explanation:
Find the radius r by finding the distance between (12,-1) and (0,-1) using the distance formula.
The radius is 12.
So the circumference of the circle is 
So the area of the circle is 
You could use a method called cross products to solve this proportional equation. What you would do is multiply 3.4*7.7 =2.17*x
If multiplied correctly, your equation should be 26.18 = 2.17x
You are trying to get the variable alone on one side. To do this, you have to undo the multiplication of the coefficient. The opposite of multiplication is division, so you would divide both sides by 2.17.
If done correctly, your equation should now be x=<span>12.064516129
However, this can be rounded to x= approximately 12.066

Answer:
5 + i
Step-by-step explanation:
The complex conjugates theorem states that if (a + ib) is a root of a polynomial equation then the complex conjugate (a - ib) will also be its root.
Now, in our case (5 - i) is a root of a polynomial.
The complex number (5 - i) has conjugate and it is (5 + i).
Therefore, (5 + i) will also be a root of the same polynomial. (Answer)
Sean drove at a faster rate because if you divide each miles/minutes then it gives you how many miles per minute they drive. 20/5 is 4, and 45/9 is 5, and 5 is greater than 4.
