Kajal holds a ruler in some wavy water. The depth of the water t seconds after she measuring it, in cm, is given by D(t)=50-23sin(π(t+0.23))
After she starts measuring, when is the first time the depth of the waves is at its average value? Give an exact answer.
When t= ___ seconds.

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.

hope this !

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
