The edge would be 9.5
The volume would be 857.38
Answer: 40 is the old value and 46 is the new value. In this case we have a positive change (increase) of 15 percent because the new value is greater than the old value.
Step-by-step explanation: brainliest please :]
The function notation f(x)=2x-4 means replace the x on the right-hand side with the value in parentheses on the left.
For example, f(y)=2y-4; f(4)=2(4)-4=4; f(1)=2(1)-4=-2 and so on.
The same principle applies to g(x), for example
g(2)=4(2^2)-3=13,
g(x+1)=4(x+1)^2-3=4(x^2+2x+1)-3=4x^2+8x+4-3=4x^2+8x+1
and so on.
(g of f)(x) is another way to write g(f(x)), therefore
g(f(x))
=g(2x-4) [because f(x)=2x-4
=4(2x-4)^2-3
=4(4x^2-16x+16)-3
=16x^2-64x+64-3
=16x^2-64x+61
Answer:
Step-by-step explanation:
To find the answer we have to first group the like terms:
therefore
so
