Answer:
distance
Step-by-step explanation:
Point B must be the same distance from the origin as point A.
What is Rotation?Rotation is a kind of geometric transformation where a figure or point is rotated by a certain degrees about a given point.
Given that,
Point B is the image of the point A when A is rotated 90° counterclockwise around the origin.
A point P(x, y) after the rotation of 90°counterclockwise around the origin is P'(-y, x).
So the x coordinate changes to the negative of y coordinate and y coordinate changes to x coordinate.
Distance between P(x, y) from origin (0, 0) is √(x² + y²)
Similarly the distance P'(-y, x) from origin (0, 0) is √((-y)² + x²) = √(x² + y²)
Hence they are at the same distance.

A construction crew is paving a road. The crew has already paved 1,000 square feet and can pave at a rate of 300 square feet of road per hour. The function f(x) = 300x
Answer:
Step-by-step explanation:
i go to southwind what’s the answer ??
The crew would spend 3.33 hours to pave a road that is 1,000 ft².
A linear equation is in the form:
y = mx + b;
where y, x are variable, m is the slope of the line and b is the y intercept.
Let f(x) represent the amount of space paved in x hours.
Given the function:
f(x) = 300x
Therefore to pave 1000 ft²:
1000 = 300x
x = 3.33 hours
The crew would spend 3.33 hours to pave a road that is 1,000 ft².
