Find the equation of the line passing through the point (1,−5) and perpendicular to y=18x+2
sleet_krkn [62]

Step-by-step explanation:

m1.m2 = -1

18.m2 = -1

m2 = -1/18

formula = y - y1 = m2 ( x - x1)

y - (-5) = -1/18 ( x -1)

y + 5= -1x/18 +1/18

y = -1x/18 -89/18

The position s(t) of a robot moving along a track at time t is given by s(t)=9t^2−90t+4.
Xelga [282]

The total distance traveled by the robot from t=0 to t=9 is 1422 units

Integration is a way in which smaller components are brought together in pieces to form a whole. Integration can be used in finding areas, volumes and so on.

Given that the position s(t) at any time t is given by the function:

s(t)=9t²−90t+4

The total distance traveled by the robot from t=0 to t=9 can be gotten by integrating the position function within the limits 0< t < 9

Therefore:

Total\ distance = \int\limits^9_0 {s(t) \, dt \\\\Total\ distance = \int\limits^9_0 {(9t^2-90t+4) \, dt\\\\Total\ distance = [3t^3-45t+4t]_0^9\\\\Total\ distance=-1422\ units

The total distance is 1422 units
