Answer: B. neither

<u>Step-by-step explanation:</u>

A function is even when f(x) = f(-x).

A function is odd when f(-x) = -f(x).

f(x) = 2x³ - x²

f(-x) = 2(-x)³ - (-x)²

= -2x³ - x²

f(x) = 2x³ - x² ≠ f(-x) = -2x³ - x² so it is NOT EVEN

-f(x) = -(2x³ - x²)

= -2x³ + x²

f(-x) = -2x³ - x² ≠ -f(x)= -2x³ + x² so it is NOT ODD

Therefore, it is NEITHER even nor odd.

równanie zmiany prędkość autokaru poruszającego się po prostym odcinku szosy i rozpoczynającego hamowanie od szybkości 20m/s ma

Rasek [7]

Answer:

s = 22.5 m

Step-by-step explanation:

the equation for the speed change of a coach moving along a straight section of the road and starting braking at a speed of 20 m / s has the form v (t) = 25-5t. Using integral calculus, determine the coach's braking distance.

v (t) = 25 - 5 t

at t = 0 , v = 20 m/s

Let the distance is s.

$s =\int v(t) dt\\\\s =\int (25 - 5t)dt\\\\s= 25 t - 2.5 t^2 \\$

Let at t = t, the v = 20

So,

20 = 25 - 5 t

t = 1 s

So, s = 25 x 1 - 2.5 x 1 = 22.5 m
