Answer:

D

Step-by-step explanation:

Just by looking at the data, you cannot answer A, B, or C because they are asking for who. There is no information on the data on WHO each piece of data is referring to. You can only answer D, which asks for HOW MANY. You can count how many 8s there are and answer the question.

V125BC [204]

Answer:

<u>Given </u>

  • f(x) = 3 + 6x

A

<u>Find the inverse of f(x):</u>

  • x = 3 + 6f⁻¹(x)
  • 6f⁻¹(x) = x - 3
  • f⁻¹(x) = (x - 3) / 6

B

  • f · f⁻¹( ∛5/6) =
  • f( f⁻¹( ∛5/6)) =
  • f((∛5/6 - 3)/6) =
  • 3 + 6((∛5/6 - 3)/6) =
  • 3 + ∛5/6 - 3 =
  • ∛5/6

C

  • f · f⁻¹(x) =
  • f(f⁻¹(x)) =
  • f((x - 3)/6) =
  • 3 + 6(x - 3)/6 =
  • 3 + x - 3 =

iris [78.8K]
8\times10^9=2^{12}\times5^9

1) Since in the USA 8 x 10 ^9 messages are sent every month, that means that approximately 8 billion messages are sent.

2) We can Prime factorize it:

Note that on the right side we've picked only prime numbers. In this case, 2 and 5.

So we can rewrite 8 x 10^9 as prime factors.

8\times10^9=2^{12}\times5^9

3) Hence, the answer is:

8\times10^9=2^{12}\times5^9

The sum of two numbers is six, and the difference is 10. Find the numbers.
pashok25 [27]
First no. = x 
Second no. = y

Equation Formation
x + y = 6..........equation(i)
x - y = 10...........equation (ii)


x = 6 - y
6 - y - y = 10
6 - 2 y = 10
-2 y = 10 -6
-2 y = 4
   y = -2

x = 6 + 2
x = 8

Answer = 8 , -2
