Answer:
Plant A produced 15,000 panels.
Step-by-step explanation:
Let plant B produce x panels
Plant A then produced x - 2000 panels
2% of panels from plant A were defective
3% of panels from plant B were defective
The two plants together produced 810 defective panels so;
2/100(x - 2000) + 3/100(x) = 810
0.02x - 40 + 0.03x = 810
0.05x = 850
x = 17,000 panels
So plant B produced 17,000 panels
Plant A produced 17,000 - 2,000 panels = 15,000 panels.
According to my teacher she says its b
Y=v(initial)*t+1/2at^2
since the velocity is zero at the maximum height then we get
y=1/2at^2
a is just acceleration due to gravity so a=g which is 9.8 m/s^2.
so y=1/2gt^2.
