Answer:
8x - 20
Step-by-step explanation:
6(2x - 3) - 2(2x + 1)
Distribute
6(2x) -6( 3) - 2(2x) -2( 1)
12x -18 -4x -2
Combine like terms
12x -4x -18 -2
8x-20
The y-intercept (initial value) is 10 and it has a slope of -1, so this is the first graph.
Answer:
The amount of nuclear fuel required is 1.24 kg.
Step-by-step explanation:
From the principle of mass energy equivalence we know that energy generated by mass 'm' in an nuclear plant is
where
'c' is the speed of light in free space
Since the power plant operates at 1200 MW thus the total energy produced in 1 year equals
Thus using the energy produced in the energy equivalence we get
Now since the efficiency of conversion is 34% thus the fuel required equals
Answer:
It was 26.5 degrees colder at midnight than at 2:00 pm
Step-by-step explanation:
We have that:
At 2:pm, it was 4 degrees.
The temperature dropped 2.5 degrees per hour until 9:00 pm.
From 2pm to 9pm, there are 7 hours. 2.5 per hour, it was 4 degrees at 2 pm.
So at 9 pm the temperature is:
4 - 2.5*7 = -13.5
The temperature dropped another 9 degrees by midnight.
At midnight, the temperature is -13.5 - 9 = -22.5 degrees
How much colder was it at midnight than at 2:00 pm?
2pm: 4 degrees
Midnight: -22.5 degrees
How much coldren
-22.5 - 4 = -26.5
It was 26.5 degrees colder at midnight than at 2:00 pm
