Answer:
The sheet should be turned up 7.5cm on each side to obtain maximum volume.
Step-by-step explanation:
If we make a rectangular eavesdrop, by bending the sheet along dotted line, then.
Height of eaves trough = x cm
Length of eaves trough = 600 cm
Width of eaves trough = (30 - 2x) cm
We know that Volume is given by:
V = Length · Width · Height
V = (x)(30 - 2x)(600)
V = -1200x² + 18000x
To maximize the volume, we take the derivative and put it equal to zero.
Answer:
B)
Step-by-step explanation:
To find the function which has vertex at the origin.
Solution:
For a function to have its vertex at origin the function must pass through point (0,0) which means .
We will find for each of the given functions and check if it has vertex at origin.
To find we will plugin
in the function.
A)
Vertex is not at the origin.
B)
[Any number times zero is = zero]
Vertex is at the origin.
C)
Vertex is not at the origin.
D)
Vertex is not at the origin.
