Answer:
Step-by-step explanation:
If c = 8, then:
5c^(3)+982 => 5(8)^3 + 982 = 3542
and
2c^(4)−7c = c(2c^3 - 7) => 8(2*512 - 7) = 8(1017) = 8136
So the second expression has the greater value when c = 8.
A = pi r^2
A = 3.14 x (5.5)^2
A = 94.985

Answer:
The equation for direct variation is y=kx. Direct variation is when 2 variables both change in the same direction. This means that if one variable increases, then the other does as well and vice versa. In this equation, k is the constant of variation. The constant of variation represents the relationship between the 2 variables. Additionally, the k value does not change.
To solve for k, divide both sides by x. This creates the new equation y/x=k. Using this equation, you can take 2 variables, divide them, and find the constant of variation.
For example, take the values x={1,2,3,4} and y={2,4,6,8}. Using the equation y/x=k, we can find the constant of variation. When plugging the first values of each set into the equation you get 2/1. This equals 2, proving that k=2. Even if you use the other values, like 8/4, k still equals 2.
