Answer:
1.5secs
Step-by-step explanation:
Given the expression that models the height as;
h(t) = -16t²+20t +6
The ball will touch the ground at when h(t) = 0
0 = -16t²+20t +6
Swap
-16t²+20t +6 = 0
Divide through by -2
8t²-10t-3 = 0
Expand using the general formula
t = -(-10)±√(-10)²-4(8)(-3)/2(8)
t = 10±√100+96/16
t = 10±√196/16
t = 10±14/16
t = 10+14/16
t = 24/16
t = 1.5
Hence it will take the ball 1.5secs to hit the ground
Answer:
5
Step-by-step explanation:
Whenever you multiply square roots that have the same number inside the radicand, you get the number under the radicand. For example, the square root of 4 squared will equal four. Similarly, you are simply squaring the square root of 5, so you should get 5 as your answer.
