Which transformations are needed to change the parent cosine function to
y = 3cos( 10(x-3))?
vertical compression of 3, horizontal stretch to a period of 5x, phase shift of , units to the left
vertical stretch of 3, horizontal compression to a period of phase shift of z units to the right
vertical compression of 3, horizontal stretch to a period of 101, phase shift of 3 units to the right
vertical stretch of 3, horizontal compression to a period of ố, phase shift of 7 units to the left

vertical compression of 3, horizontal stretch to a period of 10pi, phase shift of 3 units to the right

Step-by-step explanation:

the parent cosine is y=cos x, and to translate it to the answer y=3(the compression number) ( 10 (( the stretch period)) ( x-3 ((( the phase shift

you'd have to use the vertical compression of 3 because its positive, the horizontal because it is positive stretch of 10 and the right phase shift because it is negative.

The other answer is incorrect, the answer you're looking for is B on EDG

Step-by-step explanation:

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.
