The period of this function can be determined using the formula:
.
The period is
Half the period of this function is:
The function which has this period is
The first choice is correct.
It is too blurry to read it get a better camera
x+y=10
x-y=8, x=y+8
y+8+y=10
2y=2
y=1
So, x=10-y=10-1=9.
Numbers Would be 9 and 1.
C is the answer
for example
assume that the height of a rectangular prism is 2, width is 1 and length measures 3
the volume will be 6
(2*1*3)
if we multiply height with the scale factor of 1/2
it becomes 1
so the volume will be 3
(1*1*3)
this situation goes for other examples, too
good luck
