suppose that an 1994 finline produce 18.036 million lb of weed. The total World production that your total to 137 million lb of

Degger [83]

One may note the country's name is not finline or Finley, is Finland.

so, in short, if we take 137 to be the 100%, how much is 18.036 in percentage off of it?

$\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
137&100\\
18.036&x
\end{array}\implies \cfrac{137}{18.036}=\cfrac{100}{x}\implies x=\cfrac{18.036\cdot 100}{137}$

Solve this using square roots and show your work please<br> 4x^2-256=0

mamaluj [8]

Answer:

x = ± 8

Step-by-step explanation:

Given

4x² - 256 = 0 ( add 256 to both sides )

4x² = 256 ( divide both sides by 4 )

x² = 64 ( take the square root of both sides )

x = ± $\sqrt{64}$ = ± 8

Solutions are x = - 8, x = 8

If f(x)=2x and g(x)= 1/x, what is the domain of (f*g) (x)

postnew [5]

Answer:

The domain of (f*g) (x) is the set of all real numbers; ( -∞, ∞)

Step-by-step explanation:

(f*g) (x) simply means we obtain the product of f(x) and g(x). We are given that;

f(x)=2x

g(x)= 1/x

(f*g) (x) = f(x) * g(x)

(f*g) (x) = 2x * 1/x = 2

This is a horizontal line defined everywhere on the real line. The domain of (f*g) (x) is thus ( -∞, ∞)
