PLEASE HELP ASAP!!! CORRECT ANSWERS ONLY PLEASE!!!
topjm [15]

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.

Allen's daily regular wage is P1,420. This coming Christmas, his boss is asking him to work for 14 hours. How much is his DAILY
VMariaS [17]

Using proportions, it is found that his DAILY RATE on that particular day is of Php 2,420 .

  • This question is solved by proportions, using a <em>rule of three.</em>
  • In a regular 8-hour day, Allen earns Php 1420. How much will he earn on a 14 hour day?

The <em>rule of three</em> is:

8 hours - Php 1420

14 hours - x

Applying cross multiplication:

8x = 1420 \times 14

x = \frac{1420 \times 14}{8}

x = 2485

The closest option is Php 2,420.

castortr0y [4]
So, the fraction of races that he won was:

\frac{6}{36} : you need ti divide the number of occurrences by the number of possibilities.

We can simplify this:
\frac{1}{6}.

When we write it in decimals until the closest place, it's:

0.167 or 16.667%
