Answer:
a) BD = 5
b) FD = 13
Step-by-step explanation:
For both questions we follow pythagoras therom.
For the first one we do 3^2 +4^2 = 25 and then we root this answer to 5
For the second we have to find the base of GD in order to find FD. GD will be 4^2+12^2 which equals to 160 and then you root.
Finally, we can find FD which is sqaure root of 160^2 + 3^2 = 169. The square root of 169 is 13. Answer is 13.
Answer:
H.''n is not divisible by 6 and n is not divisible by both 2 and 3.
Step-by-step explanation:
We are given that a statement ''n is divisible by 6 or n is divisible by both 2 and 3.''
We have to write the negation of the given statement.
Negation: If a statement p is true then its negations is p is false.
n is divisible by 6 then negation is n is not divisible by 6.
n is divided by both 2 and 3 then negation is n is not divisible by both 2 and 3.
Therefore, negation of given statement
''n is not divisible by 6 and n is not divisible by both 2 and 3.
Hence, option H is true.
Answer:
- h = 0 when the ball hits the ground
- about 3.464 seconds
Step-by-step explanation:
The formula gives h = 192 when t=0, so we assume that h represents the height above the ground. The ball will have a height of 0 when it hits the ground.
__
Using that in the equation, we can solve for t.
0 = 192 -16t^2
0 = 12 -t^2 . . . . . . divide by 16
t^2 = 12 . . . . . . . . add t^2
t = √12 = 2√3 ≈ 3.464 . . . . take the square root
It will take 2√3 seconds, about 3.464 seconds, for the ball to hit the ground.
