Please help on this math problem> 5w^2 if w = 0.5

okay... ijust want to double check...

These are my choices:
1.25
0.065
25

... imultiplied 5 times 5... got 25.. then I multiplied by 0.5... and got 12.5...
is it the correct way of doing it??? ... again 12.5 is not a choice.
Is there a different way of doing it?

Ithink my answer is 1.25... but im not sure:/

AYUDA! please...

Thanx!

5w² if w = 0.5 means that you are to replace w with 0.5 and then do the arithmetic.

So,
5w² = 5(0.5)² = 5(0.5)(0.5) = 5(0.25) = 1.25

Hope that helps.
Have a good one!

here, we have w=0.5
Put the value of w in the question
5*0.5^2
5(0.5)^2
5*0.25
1.25

Thank you
Hope it helps

Answer is 1.25

Multiply 0.5 by 0.5.. got 0.25...
Then
multiply by 5..... and got 1.25
So,
The answer is 1.25
