Given that a triangle in the coordinate plane has coordinates of (3, 5), (1, −3), and (−3, 4). Now these points are translated and the new coordinates are (1, 7), (−1, −1), and (−5, 6).
Questioon says to find which type of translation occured from the given choices.
It can be easily found by drawing the given coordinates.
Original position of the triangle is drawn in Brwon colour.
New position of the triangle is drawn in Green colour.
From graph we can clearly see that each of the original coordinate moves two unit left then 2 units upward to get new coordinate.
Hence choice "A) It moved left two units and up two units." is the final answer.
Answer: 28 %
Step-by-step explanation:
Let, Initially,
V be the volume of construction work
r be the productivity of labor
n be the number of days
x be the number workers.
Thus, V = r × n × x ------------(1)
Now, According to the question,
The volume of construction work was increased by 60% but the productivity of labor increased by only 25%.
Therefore,
Final volume of the work = 160% of V = 1.6 V
Final productivity = 125% of r = 1.25 r
Also, the time is same in both conditions,
Final time taken = n
Let y be the number of people after changes.
Thus, 1.6 V = 1.25 r × n × y -----(2)
Dividing equation (1) by equation (2)
We get, y = 1.60 x/1.25
Thus, the changes in the number of workers
=
= 0.28 × 100
= 28 %
