Let the radius of the circle be x, then by the tangent-secant theorem
4^2 = 2(x + 2)
16 = 2x + 4
2x = 16 - 4 = 12
x = 12/2 = 6
Therefore, the radius of the circle is 6 inches.
Answer:
16.5
Step-by-step explanation:
Answer:
Step-by-step explanation:
width=√(130²-120²)=√[10²(13²-12²)]=10√(13+12)(13-12)=10√(1×25)=10×5=50 m
perimeter=2(120+50)=2×170=340 m
area=120×50=6000 m²
Answer:
h(x) = (x+2) ^2 -2x -3
Step-by-step explanation:
If we have to shift 2 units left the we have to replace x by x+2 i.e
h(x) = (x+2)^2-2(x+2)+1
= (x+2)^2 -2x-4 +1
= (x+2)^2 -2x -3
