r = sqrt(a^2 + b^2)
or
r^2 = a^2 + b^2
I'm still not convinced you're not trolling.
Those answers were wrong.....
r = sqrt(a^2 + b^2)
or
r^2 = a^2 + b^2
I'm still not convinced you're not trolling.
Dude. In your house you have something called a computer. On it, your daughter can use something called the internet. On the internet there is a search engine called Google.
And if she's getting homework on this surely she was taught this in class?
r=(a^2+b^2)^0.5 or r=sqrt(a^2+b^2) will do it. And the second one...17600?
You don't know what a product is, do you?
No, they are correct. If you are using an online program to submit the homework you are probably entering the answers incorrectly... I used webassign before and you need to enter answers in a specific way, you're gonna have to find out what that is i guess.
You probably need to answer something likeWebAssign will do simple calculations for you, using +, -, *, /, parentheses, and E-notation.
Is there some kind of penalty for wrong answers?
If you knew it was 17,600, what was all that about addition and 270.
If you don't know the difference between Sum and Product, that's one thing. Don't come back and lie to us pretending you knew what it was.
GodlessAstronomer's answers are correct. You entered them wrong or it's looking for some other form. Can you use the square root symbol?
Try
(a^2+b^2)^0.5
or
sqrt(a^2+b^2)
(Maybe it doesn't want you to put "r=" in?)
