Answer:
The equations that represent the reflected functions are
Step-by-step explanation:
The correct question in the attached figure
we have the function
we know that
A reflection across the y-axis interchanges positive x-values with negative x-values, swapping x and −x.
therefore
The reflection of the given function across the y-axis will be equal to
(Remember interchanges positive x-values with negative x-values)
An equivalent form will be
therefore
The equations that represent the reflected functions are
Step-by-step explanation:
According to the question,
l+5=2h
For a sphere, remember that the surface area is roughly 4 times the area of a circle with same radius
so
SA=4pir^2
r=8.4
we are done'
SA=4pi8.4^2
SA=4pi70.56
SA=282.24pi
aprox pi=3.14
SA=886.2336 in^2
answer is last one
