The total number of hours on stand by is 12 x 3 x 7 = 252 hrs.
The energy used would be (252 x 8.8)/1000 = 2.22 kW-hours.
Answer:
Graph D
Step-by-step explanation:
it does not pass the linear test to qualify as a function
Since they gave you the boxes you need the first number to be zero therefore having the quotient starting with zero. Then you may divide normally
F(-3)=(-3)2 - 1 / -3 + 4
f(-3)= -6 -1 / -3 + 4
f(-3)= -7/1
f(-3)=-7
Answer:
A
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [a, b ] is

Here [ a, b ] = [ 2, 6 ], thus
f(b) = f(6) = -
+ 70 = - 64 + 70 = 6
f(a) = f(2) = - 2² + 70 = - 4 + 70 = 66
average rate of change =
=
= - 15 → A
