Enter the number below in two other forms. Thirty thousand, five hundred eleven The number can be written in expanded form as The number can also be written in standard form as

a) In Expanded form = 30,511

b) In Standard form = 3.0511 × 10⁴

Step-by-step explanation:

We are given this number in words = Thirty thousand, five hundred eleven

a) Writing in Expanded form =

Thirty thousand + Five hundred + Eleven

= 30,000 + 500 + 11

= 30,511

b) Writing in Standard form = This mean writing a given number as an exponential or exponent of 10

We are given the number : Thirty thousand, five hundred eleven = 30,511

30,511 in standard form = 3.0511 × 10⁴

To answer this problem, we have to set the equation equal to zero and then solve the equation. This can be done be dividing by -16, then factoring.

0 = -16t^2 + 16t + 480
0 = -16(t^2 - t - 30
0 = -16(t - 6)(t + 5)

The solutions are 6 and -5, only 6 makes sense in the context of this problem.
