Vf²=vi²+ 2ad A) solve for vi B) solve for d Using the same equation

1 answer:

7 0

A)
Vf² = vi² + 2ad Subtract 2ad from both sides
Vf² - 2ad = vi² Find the square roots of both sides
√(Vf² - 2ad) = √(vi²) Cancel out the squares with the square roots
Vf - √(2ad) = vi Switch the sides to make it easier to read
vi = Vf - √(2ad)

B) Vf² = vi² + 2ad Subtract vi² from both sides
Vf² - vi² = 2ad Divide both sides by 2a
(Vf² - vi²) / 2a = d Switch the sdies to make it easier to read
d = (Vf² - vi²) / 2a

which is a pair of dependent events? spinning a spinner one time and then spinning it a second time flipping a quarter and then

Sphinxa [80]

<h2><u>Answer and explanation:</u></h2>

Two events are said to be dependent on each other, if the outcome of the first thing affects the outcome of the second thing in such a way that the probability changes.

Here, the right answer will be = removing a marble from a bag, not putting it back, and then removing a second marble.

Explanation:

Lets suppose there were 10 marbles in the bag at the first place. Now, you removed one marble and did not put it back. So, remaining marbles will be 9. Now, if again you choose a marble, you have 9 marbles to choose from. We can see that probability changes with the event that occurred at first place.

So, this is the right answer.

Rest options are simultaneous one. They are not dependent in any way.
