Answer:
The area of one side of the tank is
Step-by-step explanation:
A cube is a regular Polyhedron limited by six equal squares. It is also known as the regular hexahedron, or simply hexahedron.
The cube is a ortohedron, that is, it has its six faces straight and perpendicular to each other. In addition to being their rectangle faces, they are also square.
It has the following properties:
*Number of faces: 6
*Number of vertices: 6
*Number of edges: 12
*Number of edges from one vertex: 3
Being the length of the edge of the cube, then its Volume (V) is expressed by the formula: Being a the length of the edge of the cube
A fish tank is the shape of a cube. Its volume is , to calculate the are of one side of the tank, we know that each faces has the form of a square of area
.
To calculate the value of a.
Then the area of square is
Substituting the value of a
Answer:
5x - y = 27
Step-by-step explanation:
Slope is the direction of line and it is calculated as,
where (x₁, y₁) is any two points on the line.
Here, we have given that
Slope = 5 and (x₁, y₁) = (5, -2)
∴
⇒ 5(x - 5) = y + 2
⇒ 5x - 25 = y + 2
⇒ 5x - y = 27
Hence, the equation of a line is: 5x - y = 27
Answer:
Ques 1:
Let us consider the system of equations,
and
It is known that 'The intersection points of the graphs of the system of equations are the solutions of the system of equations'.
So, after plotting the given graphs, we see that from the first graph,
The only intersection point is (1,1).
Thus, the solution of the system is x= 1 and y= 1.
Ques 2:
We have the functions, f(x)= 2x+1 and g(x)= 2x^2+1.
Plotting the graphs of both the functions is shown by graph 2, we see that,
The intersection points are (0,1) and (1,3)
Hence, the function have equal values only at x= 0 and x= 1 but not at x= 3.
