Answer:
1/2
Step-by-step explanation:
area of larger square: 12 x 12 = 144
area of smaller square: 6√2 x 6√2 = 72
S/B = 72/144 = 1/2
Answer:
A. Absolute value.
Step-by-step explanation:
We are asked to determine the type of function, if it is symmetric over the line .
We know that a line of form represents an equation of a vertical line that crosses x-axis at point
parallel to y-axis.
We know that a cubic function is symmetric about origin, while an exponential function has no symmetry.
A rational function is not necessarily symmetric to y-axis.
We know that an absolute value function is symmetric about y-axis, so our given function will be symmetric to the line and option A is the correct choice.
