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
Step-by-step explanation:
The question missing attachment (incomplete)
But the question said how far up does the ladder reach on the building?
See the attachment
Let the tita be 60° and the height of the building be 50 meters
Now
Opposite/hypotenuse = sin(tita)
50/x = sin60°
Cross multiply to find x
x = 50/sin(60°)
x= 50/0.8660
x=57.7 meters

Answer: 
both zeros are irrational numbers
<u>Step-by-step explanation:</u>
Note: The question would have made more sense if if it was 2/x = x - 1 but I will answer it as written.

Answer:
your answer is c
Step-by-step explanation:
beacause the bubble is filled in if its possible for the answer to be eaqual and the other number may be larger if its not equal so its moves to the right
