Answer:
Lenght of a shadow is 96.6
Step-by-step explanation:
you may use right angle triangle to find distance if you know angle of elevation.
(a) adjacent (b) hypotenuse
(c) Opposite
we know that:
adjacent (a)=40
opposite (b)=?
tan ∅= opposite/adjacent
tan 67°=opposite/40
2.4142 * 40 = adjacent
adjacent =96.6
Answer:
derivative of the vector function given = ( -16-22t, 14-36t, -2-16t )
Step-by-step explanation:
given data:
vector function : r(t) = ta*(b+tc)
a = ( 2,-3.4) . b = (-4,5,-1). c = ( -2,-1,5)
to find the derivative of the vector function we will differentiate with respect to x attached below is the detailed solution
