The paddle wheel of a boat measures 16 feet in diameter and is revolving at a rate of 20 revolutions per minute. The maximum depth of the paddle wheel under water is 1
foot. Suppose a point is located at the lowest point of the wheel at t=0. Write an
equation for the height of the initial point after t seconds.
A h= -8 cos 3t + 7
B h= 8 cos (Ft) +7
C h=8 cos (Ft) + 7
D h= 8 cos 3t +7

we need the options

step-by-step explanation:

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.

76%

step-by-step explanation:

24% are dogs and the remaining is 76% because 100-24=76
