Question

Idk if I'm doing this right can someone help me?

Answer 1

What's your problem?

Answer 2

I got this problem I'm doing n idk if I'm doing it right

Answer 3

What's the original question?

Answer 4

Well I have to find a landing point of a basketball and I have to use this equation in quadratic formula.

Answer 5

Here

Answer 6

Your math is correct so far!

Answer 7

Thanks but I'm stuck on the quadratic formula

Answer 8

In another situation, you may be required to do it by hand, but when you're looking for an exact answer, as seen here, just use a calculator to calculate the answer to about 2 or 3 decimal places, or as your instructor dictates. What do you get?

Answer 9

Like my teacher told me that use the quadratic formula to find the landing point because I use the calculator and the last point was negative and it can't go negative

Answer 10

As you can see from the graph and table

Answer 11

You're correct. And you may or may not be noticing it, but do you not get two different answers?

Answer 12

No I don't like I'm confused

Answer 13

So, the quadratic formula can be solved in two ways because of its "plus or minus" notation. Because of it, you can either solve it by adding or subtracting the square rooted value from the first value. As such, you'll get two different outcomes. Now, one will be negative, and obviously that's false, but one is positive, leaving that as the only possible answer. What is the positive answer one would get?

Answer 14

Oh I didn't know that and I don't know but wouldn't it be a high number?

Answer 15

Actually, no. In this case it works out to a small number. Though, that number could be significant depending on your original question. So, try running the equation with the "plus or minus" replaced as a minus sign instead. What do you get?

Answer 16

I get -30

Answer 17

I don't know the answer

Answer 18

Sorry for the late response. How'd you get that?

Answer 19

I'm gonna go, so just know that in order to solve the problem, you have to run it as "(-35-sqrt(1609))/-32". It should compute to about 2.347 units.

Answer 20

Ohh now I get it because I was stuck at -35sqrt(1609)/-32. So the landing point of my problem is 2.347?

Answer 21

Yep!
