Answer:
The coordinates of point X are (-11/2, 5/2)
Step-by-step explanation:
To find the coordinates of X , we shall apply the midpoint formula;
Mathematically, that would be;
(x , y) = (x1 + x2)/2 , (y1 + y2)/2
From the question
x1 = -3 , x2 = -8
y1 = 1 , y2 = 4
So substituting these values, we have;
(x ,y) = (-3-8)/2, (1 + 4)/2
(x ,y) = -11/2, 5/2
Answer:
x=7+ the square root of 85 /2 , x = 7- the square root of 85/2

60 W = 0.06 kW
Lifetime = 0.06 kW * 190 h = 11.4 kWh
The lifetime of the bulb is 11.4 kWh, or kilowatt-hours
