Answer:
I do believe that the answer would be D. sorry if I'm wrong but I'm pretty sure it's D.
Answer:
it's inverse is:
f(x)^-1 = (x+10)/2
Step-by-step explanation:
f(x)= 2x -10
y= 2x -10 [ let f(x) be y]
interchange value of x and y
x=2y -10
(x+10) = 2y
y=(x+10)/2
f(x)^-1 = (x+10)/2
1.5 tsp x 800 cakes = 1200 tsp.
1 tsp = 5 ml
1200 x 5 = 6000 ml
1 ml = 0.001 liter
6000 x 0.001 = 6 liters
Given:
Q = 0.0764 kJ = 764 J, heat input
W = -830 J, useful work done
From the 1st Law of Thermodynamics, the change in internal energy is
δE = Q - W
= 764 - (-830)
= 1594 J = 1.594 kJ
Answer: 1.59 kJ (two sig. fig.)
