Answer:
The circumference is around 785 feet
Step-by-step explanation:
The circumference of a circle is pi x radius x 2 or pi x diameter.
If the Ferris wheel's radius is 125, then this is what you do:
pi x 125 x 2
= pi x 250
= 3.14 x 250
= 785

Step-by-step explanation:
General quadratic equation: ax^2 + bx + c
where a is the coefficient of the quadratic term, b is the coefficient of the linear term and c is the independent term. Here the equation is: x^2 – 2x – 3, so a = 1, b = -2 and c = -3
Quadratic formula:
Replacing


The sum has a degree of 6 but the difference has a degree of 7.
For the first roll, you expect that you would get number 3 of a die.
Next for the second roll, you expect that you would get an even number. Since there are 6 sides of a die, so the even numbers are only 2, 4 and 6.
