A snowboarder's elevation, in feet, can be represented by the function E (t) = 3,000 - 70t, where t is in seconds. Graph the function and find the elevation of the snowboarder after 40 seconds.

After 40 seconds, the snowboarder is at _ feet

step-by-step explanation:

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

85.3-64 = 21.3

so laura has already added 85.3 grams of chocolate powder and she has gone over the amount specified in the recipe by 21.3 grams

hope i ! have a great  day!

0.5?
