Answer: The area of one wall is 216.72 ft^2.
Step-by-step explanation:
16.8 * 12.9 = 216.72
x\4 = 5\7
The distance an object falls in 4 seconds is 256 feet.
Given,
The expression 16t² models the distance in feet that an object falls during t seconds after being dropped.
We need to find out what distance will an object fall in 4 seconds.
A function has an input and an output.
Example:
f(x) = x + 1
x = 1
f(1) = 1 + 1 = 2
Input = 1
Output = 2
Find the expression that describes the distance at t seconds.
= 16t²
Find the distance at t = 4.
We have,
= 16t²
= 16 x 4²
= 16 x 16
= 256
Thus the distance an object fall in 4 seconds is 256 feet.

1. it fell in 2 seconds so plug the "t" with 2
2. 16*4² ⇒ 4² = 16
3. 16*16 = 256
The equivalent expression is:
The expression is given as:
Simplify
Apply the law of indices
