Answer:
The geometric mean of the measures of the line segments AD and DC is 60/13
Step-by-step explanation:
Geometric mean: BD² = AD×DC
BD = √(AD×DC)
hypotenuse/leg = leg/part
ΔADB: AC/12 = 12/AD
AC×AD = 12×12 = 144
AD = 144/AC
ΔBDC: AC/5 = 5/DC
AC×DC = 5×5 = 25
DC = 25/AC
BD = √[(144/AC)(25/AC)]
BD = (12×5)/AC
BD= 60/AC
Apply Pythagoras theorem in ΔABC
AC² = 12² + 5²
AC² = 144+ 25 = 169
AC = √169 = 13
BD = 60/13
The geometric mean of the measures of the line segments AD and DC is BD = 60/13
Answer:
Function- a relationship or expression involving one or more variables.
A domain refers to the set of possible input values.
The range is the set of possible output values.

Answer:
Step-by-step explanation:
The function whose graph is given has y-intercept (0, 3), whereas the function f(x) has y intercept (0, 1). So it is the first that has the greater y intercept.
Answer:
62%
Step-by-step explanation:
6 strips equals 60% because 6×10=60
2 squares equals 2% because 1×2=2
60+2=62
