Answer:
Function
Step-by-step explanation:
Relation we usualy represent by matrix.
Function we usualy represent bg graph, so i think this is function:)
Sign. 4 ft. 1ft shadow
Pole. Xft. 5ft shadow
X=4•5/1
X=20 ft
Flag pole is 20 ft tall
Answer:
x+8=-3 gives
x=-11 is the required value
R(t) = integral of r'(t) = integral of ti + e^tj + te^tk = 1/2t^2i + e^tj + (te^t - e^t)k + c
r(0) = j - k + c = i + j + k
c = i + 2k
Therefore, r(t) = (1/2t^2 + 1)i + e^tj + (te^t - e^t + 2)k
