Answer: 80 men

Step-by-step explanation:

Let m represent the number of men , w , the number of women and c the number of children , then we have:

m : w = 4 : 5 ............... equation 1

w : c = 10 : 9 ............ equation 2

Multiply equation 1 by 2 so as to get the ratio m:w:c , that is

equation 1 becomes : m: w = 8 : 10

so the combine ration m : w : c is 8 : 10 : 9

The total ratio is therefore 8 + 10 + 9 = 27

number of men = ratio of men/ total ratio X 270

number of men = 8/27 X 270

number of men = 8 X 10

number of men = 80

the function g(x) Is the graph below resulted from shifting the graph of f(x) down 2 units. If f’(2)=8, what is g’(2)?

Sauron [17]

We know that the graph of g(x) is the result of a shift of 2 units down from f(x).

Then, f(x) and g(x) are related by:

$g(x)=f(x)-2$

Taking the derivative:

$g^{\prime}(x)=f^{\prime}(x)$

This is because the derivative of a constant number is 0. Finally, evaluating at x = 2:

$\begin{gathered} g^{\prime}(2)=f^{\prime}(2) \\ \\ \therefore g^{\prime}(2)=8 \end{gathered}$
