**Physics**

It was correct, thank you!

**Physics**

I see, that makes sense. Thanks for the help, I'll get back about the answer:)

**Physics**

The slope of a position vs. time graph represent's the object's... acceleration displacement position speed I thought the answer should be velocity, but that's not an option. Should it be displacement then?

Find the zero of f(x) = (2^x-1)(-3^x+1). x = (ln2 + ln3)/(ln2 - ln3) x = (ln2 - ln3)/(ln2 + ln3) x = 2/(ln2 - ln3) x = - (ln5/ln1) I can't figure this out. Solve log(27)(log(x)10) = 1/3 for x. x = (3(inverse)sqrt90)/3 x = 10(inverse)sqrt3 x = 9(inverse)sqrt10 x = 3(inverse...

Use the Remainder Theorem to determine if x - 2 is a factor of the polynomial: f(x) = 3x^5 - 7x^3 - 11x^2 + 2 I am confused because I cannot rationally factor this polynomial. Does it want me to use x - 2 as a denominator?
