What is 315 written as a product of prime factors in index form? Can somebody please explain this to me in english?

dmitriy555 [2]

I'm guessing it's like this
example
18=2*3*3=(2¹)(3²)

315/5=63
63/3=21
21/3=7

factored form is 3*3*5*7=(3²)(5¹)(7¹)

Which explanation provides the best real-world scenario of the graph?

Naddika [18.5K]

The last one is the only one that makes sense according to the standard position function. -16t^2 is the pull of gravity on an object in free fall, and the height is 120 feet above the ground. Hopefully that's what you need since there's no graph we can refer to
