What is the line of reflection between pentagons pqrst and p'q'r's't' ?
a) x = 0
b) y = x
c) y = 0
d) x = 1

A

Step-by-step explanation:

From the diagram:

The general rule of this reflection is

(x,y)→(-x,y)

and this is reflection across the y-axis. The y-axis has the equation x=0.

70

step-by-step explanation:

2*5=10

4*15=60

60+10=

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²
