Problema Solution
A forensic scientist is a person who is trained to take evidence from crime scenes and determine from that evidence who may have been involved in the crime. Forensic science uses the fact that certain bones serve as excellent sources of information to determine a person's height..
For example, the femur of a male (the bone between the hip and the knee) can determine a person’s height by using the function:
h(x)=1.88x+32.01
Where h(x) is the height in inches and x is the length of the femur in inches
Show all detail calculations. When rounding express your answers in question 1 to 1 decimal place precision.(10ths)
a) How tall was a male whose femur was found to be 19.3 inches in length.
b) How long is the femur of a male that was 74 inches tall
.
c) What is an invalid value for the domain for this function? Explain why.
Answer provided by our tutors
(a)
x=19.3, y = 1.88*19.3+32.01 = 68.3
The male is 68.3 inches tall whose femur was found to be 19.3 inches in length
(b)
y = 1.88x+32.01 = 74
x = 22.3
The femur is 22.3 inches of a male that was 74 inches tall
(c)
The domain is x>0
