Answer:
Length of AB is 8cm
Step-by-step explanation:
It is a Pythagorean triple; 6,8,10
That is,
AB=√AD²-BD²
AB=√10²-6²
AB=√100-36=√64=8units
The function family that each belongs to are :
a. linear = f(x)=x+2
b. exponential = f(x)=2^x
c. quadratic = f(x)=x^2
d. linear absolute value = f(x)=|2x|
A linear function should have either one or more variables without exponential form
A quadratic function should have either one or more variables with exponential form with degree 2
An exponential function has a variable raised to the power constant
A linear absolute contains a absolute value expression
