Mathematics

Bad White [126]3 years ago
3 0
According to the equation: T = 42 - 0.7T

The temperature drop would be 420/17


Work:

Bring T to the other side
T + 0.7T = 42
1.7T =42

Divide 1.7 from 42
T = 42/1.7 = 420/17

The image of the polygon ABCDE reflected across the x-axis. A(-1,-1),B(0,1),C(4,2),D(6,0),E(3,-3) The vertices of the image are.
4vir4ik [10]

A reflection across the x-axis has the rule:

(x,y)→(x,-y).

Then:

  • A(-1,-1)→A'(-1,1),
  • B(0,1)→B'(0,-1),
  • C(4,2)→C'(4,-2),
  • D(6,0)→D'(6,0),
  • E(3,-3)→E'(3,3).

Answer: the vertices of the image are A'(-1,1), B'(0,-1), C'(4,-2), D'(6,0) and E'(3,3).
