Answer:
29.03 cm
Step-by-step explanation:
Step one:
given
A rectangular block of metal is
25cm long
11cm wide and
9cm high.
The volume of the block is
= 25*11*9
= 2475cm^3
Required
The dimension of an equivalent cube
we know that volume of cube
v=l^3
24475=l^3
cube root both sides
l= ∛24475
l= 29.03 cm
Answer:
13.5cm

At what speed can the greatest number of cars travel safely on that road? Assume that the maximum possible speed of a car is less than 300.
B. The inverse of a linear function is always a function.
C. The inverse of a quadratic function is always a function.
D. The inverse of a linear function is not a function.
The correct answer is:
A) The inverse of a quadratic function is not a function.
Explanation:
The inverse of a function is a function if and only if each element of the range (y-coordinates) is mapped to one element of the domain (x-coordinates).
Each y must be mapped to one x; this means no y can be repeated. This means if we draw a horizontal line through any part of the graph of an inverse function, it should not hit more than 1 point.
The graph of a quadratic function is a parabola, or a u-shaped graph. If we draw a horizontal line through a parabola, it will hit twice everywhere except the vertex. This means the inverse of a quadratic function is not itself a function.
