A product rule is a formal rule for differentiating problems where one function is multiplied by another.
Hope this helps!!! :)
The complete question is
<span>∠BEC is formed inside a circle by two intersecting chords. If minor arc BD = 94 and minor arc CA = 166, what is the measure of ∠ BEC?
the picture in the attached figure
we know that
The angle formed inside of a circle by two intersecting chords is </span><span>the half-summit of the arcs that comprise it and its opposite.
so
</span>∠BED=(1/2)*[arc AC+arc BD]-----> (1/2)*[166+94]-----> 130°
∠BEC+∠BED=180°-----> by supplementary angles
∠BEC=180-130-----> 50°
<span>
the answer is</span>
∠BEC=50°<span>
</span>
It’s a because it just is
Cos b, I think this should help...
Answer:
We have for velocity of package v= 20 - 9.8t and for distance from the ground y = h + 20t - 4.9t2.
We have y = 0 and t = 18.0 s we have h = 4.9·182 - 20·18 = 1227.6 m.
Velocity at landing v = 20 - 9.8·18 = - 156.4 m/s
