Answer: 0.4 meters per hour.
Step-by-step explanation:
The rate of change of distance with respect to time is known as speed.
Formula :
Given : It's raining outside, and after 1 hour of rain, the water level in Jake's pond is 2 meters. After 3 hours, the water level is 2.8 meters.
i.e. Change in position= 2.8-2=0.8 meters
Change in time = 3-1=2 hours
i.e.
Hence, the rate of change =0.4 meters per hour.
Answer:
A'(-2, 1), B'(1, 0), C'(-1, 0)
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, dilation and translation.
If a point X(x, y) is translated a units right and b units down, the new location is X'(x + a, y + b) whereas if a point X(x, y) is translated a units left and b units up, the new location is X'(x - a, y - b).
If a point X(x, y) is rotated 90° clockwise about the origin, the new location is X'(y, -x)
From the image attached, ∆ABC is at A(0, 0), B(1,3) C(1, 1)
If ∆ABC is translated 2 units down and 1 unit to the left (x - 1, y - 2), the vertices would be A*(-1, -2), B*(0, 1), C*(0, -1)
If it is then rotated 90° clockwise about the origin, the new location is A'(-2, 1), B'(1, 0), C'(-1, 0)
Answer:
3) 2.7
Step-by-step explanation:
The distance between two points and
can be determined by:
Since the points are X(1, 2) and Y(6, 7). The distance between the two points is
the x value for the point located 1/3 the distance from X to Y,
The x value =
