Step-by-step explanation:
1. The question lack info
4 is correct
reason is because the number next to x is the constant number and the end number is where you started
Answer: The first equation is an equation of a parabola. The second equation is an equation of a line.
Explanation:
The first equation is,

In this equation the degree of y is 1 and the degree of x is 2. The degree of both variables are not same. Since the coefficients of y and higher degree of x is positive, therefore it is a graph of an upward parabola.
The second equation is,

In this equation the degree of x is 1 and the degree of y is 1. The degree of both variables are same. Since both variables have same degree which is 1, therefore it is linear equation and it forms a line.
Therefore, the first equation is an equation of a parabola. The second equation is an equation of a line.
Answer:
Step-by-step explanation:
you have to find what r and q is
Height of cylinder =
ft
Diameter of cylinder =
times its height =
ft
Now Radius = half of diameter =
ft
Now we have to find the Volume of cylinder
formula for Volume of cylinder is
Volume of cylinder =
let's plug the values
Volume of cylinder = 
Plug the values in calculator
= 11852.9657 cubic feet
Round off the answer to two decimal places(i.e. hundredth)
= 11852.97 cubic feet
