A kite 100 ft above the ground moves horizontally at a speed of 6 ft/s. At what rate is the angle (in radians) between the strin
arlik [135]

Answer:

0.015 radians per second.

Step-by-step explanation:

They tell us that at the moment the speed would be 6 ft / s, that is, dx / dt = 6 and those who ask us is dθ / dt.

Which we can calculate in the following way:

θ = arc sin 100/200 = pi / 6

Then we have the following equation of the attached image:

x / 100 = cot θ

we derive and we are left:

(1/100) * dx / dt = - (csc ^ 2) * θ * dθ / dt

dθ / dt = 0.01 * dx / dt / (- csc ^ 2 θ)

dθ / dt = 0.01 * 6 / (- csc ^ 2 pi / 6)

dθ / dt = 0.06 / (-2) ^ 2

dθ / dt = -0.015

So there is a decreasing at 0.015 radians per second.

What is f(4.5) what si the value of x for which f(x)=3?
notsponge [240]
It kind of looks like your missing something in you problem.  But if f(x) = 3 is correct, then it doesn't matter what x is the answer is always going to be 3.  So f(4.5) = 3.  Most of the time though f(x) means a function of x, so there is an x in the problem.  For example: f(x) = 3x, then f(4.5) = 3*4.5 = 13.5.
