Question

5.2 = 2(0.7)^2 + 4(0.7) h

- how can i get the "h" in that equation. that was 2(0.7) squared. just dunno how to do the squared thing here :) please help. ;)

Answer 1

This is what you wanted to write. The equation editor is your friend. :)
\[5.2 = 2(0.7)^{2} + 4(0.7)h\]

First combine your constants that are in the same terms.
\[2(0.7)^{2} = 2 * 0.7 * 0.7 = 0.98\]
\[4(0.7) = 2.8\]
And rewrite the equation as
\[5.2 = 0.98 + 2.8h\]
Can you go on from there?

Answer 2

is the answer h= 1.50? is it right? :/

Answer 3

It's very close to 1.5 but not exactly, because 4.22 / 2.8 does not come out even.
Do you need an exact answer, or just an approximate number?

Answer 4

the exact answer please. so 1.5 could be the answer already?

Answer 5

No. If you need an exact answer, then you either need to write it as a fraction \[4.22/2.8\] or write the complete decimal, which goes on forever: 1.507142857142857142857142857142857142857142857142857142857142857142...

Writing forever will take a very long time though. :)

Answer 6

oh yea. so i mean i need the estimated one. 1.50 would do :) thanks! :)

Answer 7

lol.

I was hoping you would not write the whole decimal. Though you could make a youtube video of yourself doing that and maybe become the next internet sensation.

Answer 8

hahha. yea thanks !! :)
