Answer:
Step-by-step explanation:
to solve this problem we can use the Pythagorean theorem
UT and TL are the legs, while LU is the hypotenuse
We have to find LU so we can proceed like this
x^2 + (x+1)^2 = LU^2
x^2 + x^2 + 1 + 2x = LU^2
2x^2 + 2x + 1 = LU^2
LU = +/-
we have to take only the positive value because a length can’t be negative.
2x^2 + 2x + 1 is positive for every value of x, so the final answer is
Answer:
The diver will hit the water at 1.5 seconds
Step-by-step explanation:
Given
Required (Missing from the question)
When will the diver hit the water?
To do this, we simply solve for t
When the diver hits the water, the height is 0 (at that point)
So, substitute 0 for h in
Divide both sides by -16
Split
or
Solve for t
or
But time (t) can not be negative.
So:
Hence, the diver will hit the water at 1.5 seconds
If you pick only positive numbers, the absolute value will have no effect, and the original set and the set of the absolute value will be exactly the same:
is still
