Divide the width by 2, as that is your scale.
26 / 2 = 13
The house would be 13 inches long.
F(n+1)=-1/2f(n)
f(n)=-2f(n+1)
given f(1)=120
-2f(1+1)=120
f(2)=-60
f(2)=-2f(2+1)=-60
f(3)=30
f(3)=-2f(3+1)=30
f(4)=-15
f(4)=-2f(4+1)=-15
f(5)=15/2
Answer:
Triangles A and E could lie on a graphed lin with a slope of 6
Triangles B and F could lie ona graphed line with a slope of 1/4
Triangles C and D could lie on a graphed line with a slope of 2/5
Step-by-step explanation:
The slope is rise over run.
Triangle A goes up 54 and to the right 9 so the slope is 54/9=6
Triangle B goes up 15 and to the right 60 so the slope is 15/60=1/4
Triangle C goes up 18 and to the right 45 so the slope is 18/45=2/5
Triangle D goes up 16 and to the right 40 so the slope is 16/40=2/5
Triangle E goes up 72 and to the right 12 so the slope is 72/12=6
Triangle F goes up 13 and to the right 52, so the slope is 13/52=1/4
From there we can find which slopes are the same.
