To avoid a storm, a passenger-jet pilot descended 0.12 mile in 0.8 minute. what was the plane's average
change of altitude per minute?
the average change in altitude was
mile(s) per minute.

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function

it's possible to build a triangle with side lengths of 3, 3, and 9.- true ( b.)

2x=70  

x=70/2

x=35

thats the answer
