Serving at a speed of 166 km/h, a tennis player hits the ball at a height of 2.8 m and an angle below the horizontal. The service line is 11.9 m from the net, which is 0.91 m high. What is the angle o such that the ball just crosses the net?
Will the ball land in the service box, whose out line is 6.40 m from the net?
Yes
No

the answer is a. hope this .

get the total number of pieces of fruit and divide it by 4 to get the average. the result is the answer to the problem. 14 total number of fruits and there are 4 members. 14 divided by 4 is equals to 3.5.

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
