Answer:
after 2 seconds
Step-by-step explanation:
We want to find t such that h = 0.
0 = -16t² +8t +48
0 = 2t² -t -6 . . . . . . . divide by -8
0 = (t -2)(2t +3) . . . . factor
The only positive solution is t = 2, which makes the first factor zero.

Answer:
Step-by-step explanation:
e) 3√2 (-3√6 -2 -6)
3√2 (-3√6 - 8)
-9√12 - 24√2
-9√(2^2 * 3) - 24√2
-18√3 - 24√2
or
6(-3√3 - 4√2)
f) -5√2 (3 + 2√2 - 6 - 1)
-5√2(-4 + 2√2)
20√2 - 20
or
20(√2 - 1)

3* 2/3 x = 4*3
2x=12
_____
2x = 2
X= 6
Answer:
True
Step-by-step explanation:
To find whether the three numbers given can make a triangle, we need to add two sides and if they are greater than the longest side, then it can be a triangle.
7 + 17 = 24
24 > 19
Since the sum of both numbers is greater, it can make a triangle.
Best of Luck!
