There is a theorem in Geometry that states that the product of one secant segment and its exterior segment equals the product of the other secant segment (in the same circle) and its exterior segment. In other words, LN x MN would half to equal PN x ON. With this equation in mind, all we have to do is substitute the lengths of the segments listed above.


(LN)(MN) = (PN)(ON)

(15 + 3)(3) = (x + 2)(2)

(18)(3) = (x + 2)(2)

54 = 2x + 4

50 = 2x

25 = x


Final Answer: x = 25

A ball is kicked upward with an initial velocity of 32 feet per second. The ball's height, h (in feet), from the ground is model
stellarik [79]

Answer:

1.        t = 0.995 s

2.       h = 15.92  ft

Step-by-step explanation:

First we have to look at the following formula

Vf = Vo + gt

then we work it to clear what we want

Vo + gt = Vf

gt = Vf - Vo

t = (Vf-Vo)/g

Now we have to complete the formula with the real data

Vo = 32 ft/s      as the statement says

Vf = 0     because when it reaches its maximum point it will stop before starting to lower

g = -32,16 ft/s²        it is a known constant, that we use it with the negative sign because it is in the opposite direction to ours

t = (0 ft/s - 32 ft/s) / -32,16 ft/s²

we solve and ...

t = 0.995 s

Now we will implement this result in the following formula to get the height at that time

h = (Vo - Vf) *t /2

h = (32 ft/s - 0 ft/s) * 0.995 s / 2

h = 32 ft/s * 0.995 s/2

h = 31.84 ft / 2

h = 15.92  ft
