Step-by-step explanation:

<u>Step 1: Define</u>

2x³y³ + 3xy - 3x³y³ + x²y - xy + 2x²y

x = -1

y = 2

<u>Step 2: Evaluate</u>

  1. Substitute:                                                                                                2(-1)³(2)³ + 3(-1)(2) - 3(-1)³(2)³ + (-1)²(2) - (-1)(2) + 2(-1)²(2)
  2. Exponents:                                                                                                         2(-1)(8) + 3(-1)(2) - 3(-1)(8) + 1(2) - (-1)(2) + 2(1)(2)
  3. Multiply:                                                                                                             -16 - 6 + 24 + 2 - (-2) + 4
  4. Simplify:                                                                                                                -16 - 6 + 24 + 2 + 2 + 4
  5. Subtract:                                                                                                             -22 + 24 + 2 + 2 + 4
  6. Add:                                                                                                                    2 + 2 + 2 + 4
  7. Add:                                                                                                                      4 + 2 + 4
  8. Add:                                                                                                                   6 + 4
  9. Add:                                                                                                                     10

Russel throws a soda from the balcony of his house to his friend Jones in the pool. If the soda is released 20 feet from the gro
stepladder [879]
Using the formula S = ut +1/2at²
S=h= 20ft, u = 2ft/s, and a = 10m/s²
Thus; 20 =2t + 20t²
Therefore; 20t²+2t-20=0
Solving the equation quadratically for the value of t,
we get; t = 1.057 or t=-1.182
But t can not be negative,
 Therefore, t= 1.1 seconds (to the nearest tenth)

Nostrana [21]

Jus combine like terms. Treat pi like a variable.

x - 8pi = pi

Combine like terms by adding 8pi to both sides to get

x = 9pi

6 is the tenth value. Round the number after 6 which is 4. Since it is less than 5, you round down. So the answer would be .6
