Answer:
16 seconds
Step-by-step explanation:
You want to find t such that h(t) = 0
h(t) = -16t^2 +4096 . . . equation for height
0 = -16t^2 +4096 . . . . .equation for height = 0
16t^2 = 4096 . . . . add 16t^2
t^2 = 256 . . . . . . . divide by 16
t = 16 . . . . . . . . . . . take the positive square root
It will take 16 seconds for the camera to hit the ground.
Answer:
10ft, 8ft and 6ft is the side measures of a right triangle.
Step-by-step explanation:
according to the pythagorus theorem the square of longest side ( hypotenuse ) should be equal to the sum of squares of remaining sides.
in triangle with sides ( 10ft, 8ft, 6ft )
the square of longest side = sum of squares of remaining sides,
10^2 = 100
8^2 + 6^2 = 64 + 36 = 100
hence it's the side measures of a right angled triangle.
and in other triangle the pythagorus theorem can't be applied hence they aren't right angled triangle
I hope this helps! I'm sorry if it doesn't:( I hope you have a wonderful day! And maybe you could mark this brainly?
Answer:
First answer choice
Step-by-step explanation:
We're willing, but sadly not able.
Here's are the other things we'll need before we can attack this one:
1). We need to know how often does Ned swim ?
2). We need to know how often does Ned bicycle ?
3). We need to see that "chart below".
The only thing I see below right now is my dog.
