Answer:
f(x) = x^2 is a classic example
f( 3 ) = 9 and
f( -3 ) = 9, but
f^(-1)[9] is undefined because the result can be 3 and -3
Answer:
is this a multiple answer question
Step-by-step explanation:
Answer:
B - 108
Step-by-step explanation:
A regular pentagon is 540 degrees. Divide 540 by 5 (since there are five sides) which equals 108 degrees.
The equation for surface area of a sphere is SA=4*pi*r^2
We can plug in what we know to solve for r
400=4*pi*r^2
100=pi*r^2 (divide out the 4)
100/pi=r^2 (divide out the pi)
√(100/pi)=r (square root of both sides)
r=5.6 rounded to the nearest tenth
Answer:
=27x6
Step-by-step explanation:
=3 × x2 × 9 × x4
=27 × x6
=27x6
