The shortest distance between your home and the mall is 3 miles or if you round it down, it will be 2.9 miles.
The time taken for the ball to fall a distance of 10feet is 1.25secs
Given the function modeled by the height expressed as:
f(t) =-16t² + 35
In order to determine the time taken by the all to fall a distance of 10 feet, hence;
f(t) = 10
10 = -16t² + 35
-16t² = 10 - 35
-16t² = -25
-t² = -25/16
t² = 25/16
t = √25/16
t = 5/4
t = 1.25secs
Hence the time taken for the ball to fall a distance of 10feet is 1.25secs

Answer:
(4a - 9)(4a + 9)
Step-by-step explanation:
Every value in the equation has a square root
The square root of 16 is 4
The square root of a^2 is a
The square root of 81 is 9.
To factor you split the equation by the square roots. For 81, since the original value is negative, one of the roots must be negative so when you multiply it back out to the original, it stays the same.
You can check your answer this way too.
(4a -9)(4a + 9)
= 16a^2 + 36a - 36a - 81
= 16a^2 - 81
