Answer:
The resulting image of given point is (-10,-1)
B is correct.
Step-by-step explanation:
A point at (−1, 10) is rotated 90°counterclockwise about the origin.
Rotation about origin counterclockwise. (Using the rule)
The x coordinate of image point is negative of y value of given point.
The y-coordinate of image point is x coordinate of given point.
-1 changes to -10
10 changes to -1
Hence, The resulting image of given point is (-10,-1)

Answer:
0ft and 60ft
Step-by-step explanation:
Given
The attached function
Required
Determine the valid values of the domain of the function
To do this, we simply consider the starting point and the end point of the trajectory on the x-axis (i.e. the horizontal distance).
From the attached graph, the horizontal distance starts from 0 and ends at 180.
This implies that the domain is:
From the options, the values that fall in this bracket are 0ft and 60ft
