5.7 is 5 7/10 and it cannot be simplified
Answer:
The last one.
Step-by-step explanation:
The solutions with the horizontal lines are wrong because then h(x) would be -1 and 1 respectively.
The subtlety is in the open or closed dot. x ≥ -1 means that -1 is included, which is drawn as a closed dot. x < -1 means that -1 is excluded, which is drawn as an open dot.
Hence the last graph is the correct one.
The gray line is longer than the white line.
The black line is longer than the gray line.
White -------------------------
Gray ------------------------------------------
Black --------------------------------------------------------
Answer: The black line is longer than the white line.
Multiply 1/3 by any number higher than 2 and you can have equivalent fractions.
Ex:
1/3×3/3=3/9
Step-by-step explanation:
Given that,
The length of a wire, L = 48 m
Current in the wire, I = 18 A (west to east)
The magnetic field in the wire, B = 
(towards south)
The magnetic force acting on the wire is given by :
Using right hand rule, the direction of magnetic force is upwards.
