A circle is centered at (-6,3) and has a radius of 11. Where does the point (3,-3) lie?
scZoUnD [109]

Answer:

Inside the circle

Step-by-step explanation:

Use the distance formula to find the distance between the center and the point.

d = √((x₁ − x₂)² + (y₁ − y₂)²)

d = √((-6 − 3)² + (3 − (-3))²)

d = √((-9)² + (6)²)

d = √(81 + 36)

d = √117

d ≈ 10.817

This is less than the radius of 11, so the point is inside the circle.

a man casts a 3 feet long shadow. if the suns rays strike the ground 62°, what is the height of the man?
Romashka [77]

Answer:

h = 3*tan(62) where h is the height

Step-by-step explanation:

You basically have a right triangle.  the standing man is the vertical line, the shadow is the horizontal line and the 62 degrees is the angle betweenthe horizontal line and the hypotenuse.

So, relative to the angle we have the adjacent angle and opposite.  What uses those?  Tangent.  tan(x) = opp / adj

tan(62) = h/3

h = 3*tan(62) where h is the height
