Question

If w(t) = t3 + t2, evaluate w(5).
100
175
150
225

Answer 1

w(5) = 150

Explanation:

w(t) = t³ + t² w(5)

w(5) = 5³ + 5²

w(5) = 125 + 25

w(5) = 150

So, w(5) = 150

Answer 2

• 150

Explanation:

w(t) = t³ + t³ - - - - (eqn. 1)

We need to evaluate w(5)

Simply put w = 5 in equation 1.

• w(5) = 5³ + 5²
• w(5) = 125 + 25
• w(5) = 150

Therefore, w(5) is 150.
