"Old" is the first (previous) quantity

Here, New = 5.3  &  Old = 17.71

We substitute into formula and find:

So we can say that the percentage decrease is 70%

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.
