An anthropologist studies a woman's femur that was uncovered in Madagascar. To estimate the woman's height, he uses the equation
Lelu [443]

Answer:

The inequality f>40 represents the length of the femur for which the woman had a height greater than 160cm.

Step-by-step explanation:

The given equation is

h=60+2.5f

Where, h is woman's height in centimeters and f is length of the femur in centimeters.

If woman's height is greater than 160cm, then

h>160

60+2.5f>160

Substract 60 from both sides.

2.5f>100

Divide both sides by 2.5.

f>40

Therefore the inequality  f>40 represents the lengths of the femur for which the woman had a height greater than 160cm.

Answer:

42 acres to 72 acres, there is an increase of 30 acres

percentage wise

72-42=30

30/72=.4166...

therefore there is also a 41.6% increase

Step-by-step explanation:

71.42 Percentage change:×100%

Now, the change is given from 42 acres to 72 acres, therefore

Change= 72-42=30

⇒Percentage change= ×100%

                                   = 71.42

2 Select the correct answer. What is the inverse of function ? F(x)=10/9x+11 A.f-1(x)=9x-99/10 B.f-1(x)=9/10x+11 C.f-1(x)=9x+11/
Lilit [14]

Consider f(x)=y.

\begin{gathered} f(x)=y \\ x=f^{-1}(y) \end{gathered}

Simplify the equation f(x)=y to obtain the value of x in terms of y.

\begin{gathered} f(x)=y \\ \frac{10}{9}x+11=y \\ \frac{10}{9}x=y-11 \\ 10x=9y-99 \\ x=\frac{9y-99}{10} \end{gathered}

So inverse of function is,

f^{-1}(x)=\frac{9y-99}{10}

Correct nswer is A part.

djverab [1.8K]
Lime m is neither because it does not have the opposite reciprocal nor same slope.
Line n is perpendicular because it has the opposite reciprocal. 
Line p is neither because it does not have the opposite reciprocal nor same slope.
Line q is parallel because it has the same slope.
