Find the length of AB
AB²=20²+15²
AB²=400+225
AB²=625
AB=25
then find AD and BD
20²=AD·25
400=AD·25
AD=16
15²=BD·25
225=BD·25
BD=9
now use the geometric mean theorem (name?) to find CD
CD=√(9·16)
CD=√144
CD=12 cm
Answer:
ticket=10 Popcorn=5
Step-by-step explanation:
Because 10 is twice as large as 5
A. c <= -4 so is the top graph;
b. c > 4 so is the second graph;
c. c < 10 so will be a graph with an open circle starting at 10 and going left towards negative infinity
Y= -1/3x is the equation of tge perpendicular line
