Why is Pi never ending?

1 answer:

6 0

If the decimal expansion of pi would end, then it would have to be a rational number, ie pi could be written as a fraction pi = p/q with integers p and q. There are many proofs that this is not the case, but they are all a bit complicated

Answer:

195 ft

Step-by-step explanation:

The relationship between the horizontal distance, angle, and vertical height is given by ...

Tan = Opposite/Adjacent

Referring to the attached diagram, we have ...

tan(16°) = BT/MB

tan(25°) = BK/MB

Solving for BT and BK, we can describe their difference as ...

BT = MB·tan(16°)

BK = MB·tan(25°)

BK -BT = 35 = MB(tan(25°) -tan(16°))

Dividing by the coefficient of MB gives ...

MB = 35/(tan(25°) -tan(16°)) = 35/0.179562

MB = 195 . . . feet

Marcos is standing 195 feet from the base of the tree.

Tell whether the valuation is a solution of the inequality r + 4 > 8 ; r = 2

aleksandr82 [10.1K]

Answer:

Not a solution.

Step-by-step explanation:

Step 1: Write inequality

r + 4 > 8

Step 2: Solve for <em>r</em>

Subtract 4 on both sides: r > 4

Step 3: Determine

r = 2

2 > 4 = FALSE
