2800 + 0.08s = 3300 + 0.06s
0.08s = 0.06s = 3300 - 2800
0.02s = 500
s = 500 / 0.02
s = 25,000 <==
Answer:
38.6m
Step-by-step explanation:
Theory of solving angle of elevation problem bus to take it as a right angle triangle.
The length of the the rope is the hypotenuse and the angle formed is the hypotenuse angle.
To determine the height , we take the side as opposite the angle.
Sin (angle) = height/hypotenus
Sin40= height/60
0.6428 *60 = height
38.568 = height
Approximately 38.6m
The desired plane will have a direction vector that is perpendicular to that of the given line (4, -3, 1) and that of the given plane (2, 5, 4). Computing the cross product of these gives (-17, -14, 26).
Since the plane contains the point (-4, -3, -1), we can find the constant (d) in ax+by+cz=d using the dot-product of the point and the direction vector just found.
-17·(-4) -14·(-3) +26·(-1) = 68 +42 -26 = 84
Your plane can be written as
-17x -14y +26z = 84
Solving for z, you get
z = (17x +14y +84)/26
or, if you prefer, ...
z = (17/26)x +(7/13)y +42/13
Given:
No of users in February is 45,000 and in october its 60,000.
t=2
Therefore, approximate no of users after 2 years is 106667.
