The function H described by H(x)=2.75x + 71.48 can be used to predict the height, in centimeters, of a woman whose humerus (the bone from the elbow to the shoulder) is x cm long.
Predict the height of a woman whose humerus is 38 cm long?
This is just "plug 'n chug". You are given the value substitute it into the equation and use a calculator.
To predict the height of a woman whose humerus is 38 cm long using the function H(x) = 2.75x + 71.48, you can substitute the value of x (humerus length) with 38 in the function and solve for H(x), which represents the predicted height of the woman.
By substituting x = 38 into the equation H(x) = 2.75x + 71.48, we get:
H(38) = 2.75(38) + 71.48
To find the value of H(38), we can calculate the expression on the right-hand side of the equation:
2.75(38) + 71.48 = 104.5 + 71.48 = 175.98
Therefore, the predicted height of a woman with a humerus length of 38 cm is approximately 175.98 cm.
