Answer: The ball will hit the ground 4 seconds after being thrown.
Step-by-step explanation:
By definition, the ball hits the grounds when the height is zero.
Then, knowing that the Quadratic function that models that situation is:

You can make it equal to zero:

Now you can use the Quadratic formula:

In this case you can identify that:

Therefore, knowing these values, you can substitute them into the Quadratic formula and then evaluate, in order to find the solution:

Choose the positive solution.
Then, the ball will hit the ground 4 seconds after being thrown.
I dont know how to help you bud give me a geometry and I could maybe solve it lol
The measure of BDA is 40 degrees
Answer:
g = 7 1/3
Step-by-step explanation:
- Add 5 to both sides so it cancels out. 3g = 22
- Divide both sides by 3. g = 7.333...
7.333... and 7 1/3 are equivalent, so just put either one.
