Answer:

-3b³ + 3ab - a + 10

Step-by-step explanation:

2a³ - 3b³ + 7 - a³ + b³ + 3ab - a - (a³+b³-3)

2a³ - 3b³ + 7 - a³ + b³ + 3ab - a - a³ - b³ + 3

-3b³ + 3ab - a + 10

Solution:

<u>Simplify the expression and solve.</u>

{(2a³- 3b³ + 7) + (-a³ + b³ + 3ab - a)} - {a³ + b³ - 3}
=> {2a³- 3b³ + 7 - a³ + b³ + 3ab - a} - a³ - b³ + 3
=> {a³- 2b³ + 7 + 3ab - a} - a³ - b³ + 3
=> {a³- 2b³ + 7 + 3ab - a} - a³ - b³ + 3
=> -3b³ + 7 + 3ab - a + 3
=> -3b³ + 10 + 3ab - a

The solution to this algebraic problem is -3b³ + 10 + 3ab - a.

Answer:

Step-by-step explanation:

angular frequency

ω = 2π/ T = 2π/4 = π/2 rad/s

A = 7 inch

Starts at rest (maximum swing, |A| = 7) so cosine function is easiest

x = -7cos(πt/2)
