Answer:
1545.66 rad/h
Step-by-step explanation:
We need to find the angular velocity in rad/hour when wind is moving with a speed of 4.1 rpm.
We know that,
1 revolution = 2π rad
1 hour = 60 minute
So,
So, the required angular velocity is 1545.66 rad/h.
For this case we have the following equation:
y = 2x - 2
For the point (1, 0) we have:
x = 1
y = 0
Substituting values we have:
0 = 2 (1) - 2
0 = 2 - 2
0 = 0
We observe that equality is fulfilled and therefore, the point belongs to the equation.

Answer:
Option a is correct.
The rotation for the transformation to △A'B'C' is , rotation of 90 degree.
Explanation:
In △ABC
The coordinate of point A = (1,1) , B = (3,1) and C = (1,4).
Rotate triangle ABC 90 degree's around the origin;
The rule for this transformation is:- (x,y) to (-y ,x)
A(1,1) to A' (-1,1) ,
B(3,1) to B'(-1 , 3) and
C(1,4) to C' (-4,1)
therefore, rotation of 90 degree counter clockwise rotation around the origin results in the transformation of △ABC to △A'B'C'
There is no y in this question, however we can solve for t.
1.4t - 0.4(t - 3.1) = 5.8
1.4t - 0.4t + 1.24 = 5.8
t + 1.24 = 5.8
t = 4.56
