Answer:
ln(2) + 3ln(a) - 4ln (b)
Step-by-step explanation:
ln(2a^3 /b^4)
We know that ln(x/y) = ln (x) - ln y
ln(2a^3 ) - ln (b^4)
We know that ln (xy) = ln x + ln y
ln(2) + ln(a^3 ) - ln (b^4)
We know that ln(x^y) = y ln (x)
ln(2) + 3ln(a) - 4ln (b)
Yap,
It seems to me that there are two answers. Both y = .5x and y = 12x. Direct variation is what I'm thinking of so hopefully this helps.
BTW - with Direct Variation, the line will go through (0, 0).
Pythagorean theorem is all about squaring the numbers. the equation is a^2+b^2=c^2
when you know two sides of the triangle, you fill in those spaces. they hypotenuse is ALWAYS ‘c’
to figure this problem out you put
a as 4
keep b as b since you don’t know what it is
c as 6
4 squared=16
6 squared=36
16+b^2=36
36-16=20
square root of 20 is 4.47
