Answer:
The length of x is 4
Step-by-step explanation:
The scale factor is Large/small where 10/8 which is DF/AC.
THE SCALE factor is 5/4.
To find the length of X is in AB we use the scale factor 5/4 and the corresponding DE.
5/4 = DE/AB
5/4 = 5/X
X = 4
To find Y in EF will use the corresponding BC which is 6.
5/4 = EF/BC
5/4 = Y/6
Y= 7.5
info: use CORRESPONDING ABC AND DEF .
X = 3
and
formula -
(y-y1)/(x-x1) = (y2-y1)/(x2-x1)
(x1,y1) = (4,1)
(x2,y2) =( 5,3)
(y-1)/(x-4) = (3-1)/(5-4)
y-1/x-4 = 2/1
y-1 = 2x - 8
y = 2x - 7
the solution will be x= 3 and y = -1
ANSWER
The pendulum's maximum displacement is 2cm.
EXPLANATION
The maximum value of the graph is the pendulum's maximum displacement.
The graph is a periodic function
The amplitude of the graph is 2.
The range of the graph is -2≤y≤2
The maximum value is 2.
The pendulum's maximum displacement is 2cm
The correct choice is B.
Well the distance from the two points is 15 so that means the midpoint in -10+7.5=-2.5. There you go! Have a nice day.
