Step-by-step explanation:
<u>Value of functions</u>
To evaluate a function for a given value of x, we replace the x for the value and perform the resulting operations.
The given function is (corrected):
We need to find f(-4), so we use x=-4:

The complete question in the attached figure
we know that
factor scale=1/13
factor scale=[dimension smaller rectangle]/[dimension original rectangle]
so
[dimension smaller rectangle]=[factor scale]*[dimension original rectangle]
a) for l=36 cm in the original rectangle
[dimension smaller rectangle]=[1/13]*[36]--------> 2.77 cm
b) for w=28 cm in the original rectangle
[dimension smaller rectangle]=[1/13]*[28]--------> 2.15 cm
c) [area smaller rectangle]=2.77*2.15------> 5.96 cm²

Answer:
mass = 3.645 g
volume = 9×9×9
= 729 cm³
density = 3.645/729
= 0.005 gcm^-3
Step-by-step explanation:
the volume is 729 cm³ cause the given height is 9cm and it is a cube. cube has equal sides so their lengths are the same.
volume = length × height × width
