Isaiah editited his post, it's not your computer.
Rewrite the left-hand side of the equation. 2.128 = 266/125: 266/125 = e^μ w
Reverse the equality in 266/125 = e^μ w in order to isolate w to the left-hand side. 266/125 = e^μ w is equivalent to e^μ w = 266/125: e^μ w = 266/125
Solve for w. Divide both sides by e^μ: w = (266 e^(-μ))/125
its ok
Oops, sorry. On my computer screen, it came out as ^ for some reason. I had to reload the page a couple of times.
Sorry.
look again
I think that is an exponent sign
Ex: 2^2 is 2 to the power of 2.
this is a root sign, √
the calculator sid the answer is, w=(ln((266/125))/ln(e))
which is a bit of a mouthful.
Oh...it's a V?
I thought it was a root sign.
Anyway, if it was meant to be a root sign, then the answer would be 1/144 because there are no brackets.
If there were brackets - sqrt(1/144) - then the answer would be 1/12.
it's v times one divided by 144, but there is no value for v so the equation cant be solved and the equation is true.
First of all, act like the < is a =. this helps for the first part. so the equasion would look like 9(2r-5)-3=7r-4
Now simplfy it.
9(2r-5)-3<7r-4
18r-45-3=7r-4
18r-48=7r-4
Now get r on one side.
18r-7r-48=7r-7r-4 r<4 is the answer
11r-48=-4
Get r alone
11r-48+48=-4+48
11r=44 r=4 r<4 Divide and get the answer for r. Now you go back and see if the inequality changes at all (which it doesn't.)
heureka made a simple mistake in copying:
1.15 million / 18,075 =63.6238 Sq. Km- The area of the city region.
63.6238 = Pi x r^2
r^2 = 63.6238 / Pi
r^2 =20.252 take the sqrt of both sides
r = ~4.50 Km radius of the region
this hurts my brain, lol
As you have it written:
2,500,000 This is in standard form.
2.5 x 10^6 This is in scientific notation.
2500000=2.5∗106
100 ---> 1*10^2
150 ---> 1.5*10^2
2500 ---> 2.5*10^3
2500000 ---> 2.5*10^6
So basically it has to be in the format:
(number from 1-10)*10^n
where n is the number of left shifts of the decimal point in order to get to a number between 1 and 10.
Thank you, Ghosty. That means so much to me, especially since I'm going through a lot right now.

hi fabio
Um...hello.
Please keep the math questions, about math.
seems reasonable
