Answer:
(A)62.8 square feet
Step-by-step explanation:
Height of the barrels = 5 feet
Radius of the barrels= 2 feet
=3.14
The barrel is in the shape of a cylinder and the area of the label the company needs is that of the round sides(curved surface area) of the cylinder.
Curved Surface Area of a Cylinder=![2\pi rh](https://tex.z-dn.net/?f=2%5Cpi%20rh)
=2X3.14X2X5
=62.8 square feet
The company need 62.8 square feet of label.
Answer:
(a) No solution
(b)
![(x_1,y_1) =(-3,-3)\\(x_2,y_2) =(4,4)](https://tex.z-dn.net/?f=%28x_1%2Cy_1%29%20%3D%28-3%2C-3%29%5C%5C%28x_2%2Cy_2%29%20%3D%284%2C4%29)
(c) ![(-6,1)](https://tex.z-dn.net/?f=%28-6%2C1%29)
Step-by-step explanation:
Given
See attachment for graph
Solving (a): Solution to p(x) and f(x)
Curve p(x) and line f(x) do not intersect.
So, there is no solution to the pair of p(x) and f(x)
Solving (b): Two solutions to f(x)
This means that we select any two point on straight line f(x)
From the line of f(x), we have:
![(x_1,y_1) =(-3,-3)\\(x_2,y_2) =(4,4)](https://tex.z-dn.net/?f=%28x_1%2Cy_1%29%20%3D%28-3%2C-3%29%5C%5C%28x_2%2Cy_2%29%20%3D%284%2C4%29)
Solving (c): Solution to p(x) = g(x)
Here, we write out the point of intersection of p(x) and g(x)
From the graph, the point of intersection is: ![(-6,1)](https://tex.z-dn.net/?f=%28-6%2C1%29)
Answer:
There are several ways to graph a continuous function. I advise you to graph several points that belongs to the function and then join the points.
If the function is linear, two points will be enough to build the graph. If we have functions of higher degree, is better to plot some points, observe the pattern and then join the points.
If the function is extremly difficult to graph by hand, the help of a graphing calculator may be needed.
