Answer:
Step-by-step explanation:
We know that,
Volume of cube = (side)^3
Fro side length s , we can write:
V(s) = s^3 , where volume is the function of s.
Now ,
We have given : v(4) = 64
If we compare this with v(s) = s^3
Then we get s =4 , i.e side length of cube is 4
Also 64 = 4^3 , i.e volume of cube is 64.
So we can interpret this as: A cube with side lengths of 4 feet has a volume of 64 cubic feet
Cubic volume=l³
l³= 1728
l= 12 feet
the aquarium is cubic shaped=> all l are equal
one side is a square with l= 12 feet
area= l²= l•l= 12•12= 144 feet²
The approximate solution to the given system of equation is (-2.71, 2.14)
<h3>Solving a system of linear equations</h3>
From the question, we are to determine the approximate solution to the given system of linear equations.
The given equations are
y = 0.5x + 3.5
y = -2/3 x+ 1/3
From the given information, we are to show the solutions on a graph
The graph that shows the solution to the given system of equation is shown below.
The solution to the given system is the point of intersection of the lines. The coordinate of the point of intersection of the lines is (-2.71, 2.14). That is, x = -2.71, y = 2.14.
Hence, the approximate solution to the given system of equation is (-2.71, 2.14)
