What is 0.25 in scientific notation ?

Mathematics

2.5 × 10 ↑ -1
Because it moves the decimal place one spot over to the left (because the one is negative), making it 0.25 once again.

What is the answer to this problem 9e+10 =
mihalych1998 [28]
E=1 because you would subtract 9 from both sides since it's on the side with the variable. The nines would cancel eachother out so you would have e on the left side then 10-9=1 so it would be e=1

Are the ratios 8/12 and 10/25 proportional? (Explain in steps)
irinina [24]
Okay, so first, lets determine whether or not these are equivalent, which will lead us to our answer. 

8/12 < lets simplify this

8/4 = 2
12/4 = 3

8/12 = 2/3

10/25

10/5 = 2
25/5 = 5

10/25 = 2/5

2/5 ≠ 2/3

These ratios are not proportional.

Answer:

f(x) and g(x) are inverses

Step-by-step explanation:

* Lets check the inverse function

- If f(x) = y has a domain = x and a range = y, then f^-1 is the

  inverse of f with a domain  = y and a range = x

- f(x) = f^-1(x) = x

* Now lets solve the problem

∵ f(x) = 8/x

∵ g(x) = 8/x

∴ fg(x) = f(8/x)

∴ fg(x) = 8/(8/x) = 8 ÷ 8/x ⇒ change division sign to the multiplication

  sign and reciprocal the fraction after the division sign

∴ fg(x) = 8 × x/8 = x

* Now lets find gf(x)

∴ gf(x) = g(8/x)

∴ gf(x) = 8/(8/x) = 8 ÷ 8/x

∴ gf(x) = 8 × x/8 = x

∵ f(x) = f^-1(x) = x

* fg(x) = gf(x) = x

∴ f(x) and g(x) are inverses
