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

h = 60 + 2.5 f, where h represents height in centimeters and f represents length of the femur in centimeters. Which inequality best represents the lengths of the femur that would suggest the woman had a height greater than 160cm?

For h = 60 + 2.5f, where h = height, in cm, and f = femur length, in cm, and the condition that h > 160cm., the minimum condition for f to meet the requirement for h will be:If h=160cm,f’ = (160-60) /2.5f’ = 40cm,with f’ = 40cm not being a solution to this inequality.
That is, all values greater than 40cm will solve the said inequality which is expressed as:f > (h-60)/2.5

Answer:

f>40

Explanation:

The given equation is  

h=60+2.5f

where h represents height in centimeters and f represents length of the femur in centimeters.

We need to find the inequality that best represents the lengths of the femur that would suggest the woman had a height greater than 160 cm.

h>160

60+2.5f>160

2.5f>160-60

2.5f>100

Divide both sides by 2.5.

\dfrac{2.5f}{2.5}>\dfrac{100}{2.5}

f>40

It means lengths of the femur is greater than 40 cm.

Therefore, the required inequality is f>40.

Point e is drawn on the graph so that line ef is parallel to line cd. If the coordinates of point e are (, y), what is the value
netineya [11]

Based on the graph given, it can be deduced from the computation that the value of y will be -8.

Point C is given as (-10 , -2)  and D = (10 , 6)

The Slope of line CD = ( 6 - (-2) /( 10 - (-10) =  8/20  = 2/5

Since EF is parallel to line CD , the slope of EF = 2/5

Equation  y  = (2/5)x  + c

5y = 2x + 5c

It passes through F ( 6 , -4)

= 5(-4) = 2*6  + 5c

= -20 = 12 + 5c

5c = -32

5y = 2x - 32

Point E ( - 4 , y)

5y = 2(-4) - 32

5y = -8 - 32

5y = -40

y = -8

Therefore, the value of y is -8.
