Answer:
2.82 seconds (3 sf)
Step-by-step explanation:
s = ut + 0.5at²
6 = -95(sin25)t + 0.5(32)t²
16t² - 40.14873487t - 6 = 0
t = 2.818501699, -0.1419193751
t is time so can't be negative.
Therefore, t = 2.82s (3 sf)

Answer:
1. No
2. Yes
3. No
Step-by-step explanation:
-4 is equal to -4 but not bigger then -4
8.5 is bigger then -4
-16 ¾ is smaler then -4
(because it is a negative number)
Answer:
B) 1 < x < 13
Step-by-step explanation:
use triangle inequality theorem which states that the sum of any two sides must be greater than the third side
let x = third side
6 + 7 > x; x < 13
6 + x > 7; x > 1
x + 7 > 6; x > -1
there will always be one inequality which produces a negative value which you can exclude from your answer because a length cannot be negative
N! means multiply the number by every number less than n
example 5! means 5 x 4 x 3 x 2 x 1
