a. Using the ratio of the sides 12 cm and 16 cm

x/20 = 12/16

x = (12(20)) / 16 = 15

b. Using the ratio of the sides 6 cm and 8 cm

x/20 = 6/8

x = (6(20)) / 8 = 15

c. The answer is the same since the ratio 12/16 and 6/8 is both equal to ¾.

Hope this answer will be a good help for you.

ANSWER

$y = 2 \sin( \theta) - 3$

EXPLANATION

The parent function

$y = \sin( \theta)$

can be shifted down by 3 units to obtain

$y = \sin( \theta) - 3$

Also, when the basic sine function is stretched vertically by a factor of 2, the equation becomes,

$y = 2 \sin( \theta)$

Therefore, a vertical shift down 3 units and stretch factor of 2 gives the equation:

$y = 2\sin( \theta) - 3$

The correct choice is E.
