50=t/2+8
50-8=t/2
42=t/2
2×42=t
84=t
check: 50=84/2+8
50= 42+8
50=50
Answer:
It takes 1 second for the tape to reach the ground.
Equation to use:
As explain above, the initial position s 16 ft, there is no initial velocity, so , and the acceleration of gravity is 32 ft/s^2, and should be considered negative [as pointing down in the y-direction], so the equation simplifies to:
In order to find the tima it takes it to hit the ground, we simple solve the equation for t when y(t) = 0 (the tape has reached the ground (zero height in the y-direction):
We select the positive time (+1 second) which is what makes physical sense, since a negative value in time would mean time before the tape was dropped.
So the answer is: It takes 1 second for the tape to reach the ground.
Answer:
B
Step-by-step explanation: If you put 7 2/5 - 5/8 in a calculator it comes to equal 6.775. Since the answer is asking for an estimate then the answer would be 7.
The answer is g (x) = (1/2) ^x-9 + 5
Just took the test and got an 80% :)
The area of the triangle must be determined. then multiply the area of the triangle by 4lb/1ft2
the equation for the area of a triangle is A = b times h/2
the base equals 5.5 feet and the height is 3 feet.
A = (5.5fttimes 3ft) /2=8.25ft2
4lb mulch is needed for each square feet
8.25ft2 times 4lbmulch/1ft2 = 33lb mulch
