Answer: The transformation <u>sin(x)-7</u> results in a vertical shift down.
The transformation <u>sin(x+7)</u> results in a horizontal shift left.
The transformation <u>sin(x)+7</u> results in a vertical shift up.
The transformation <u>sin(x-7)</u> results in a horizontal shift right.
Step-by-step explanation:
Transformation:
If f(x) is a function then
f(x)+k is a vertical shift k units upwards.
f(x)-k is vertical shift k units downwards.
f(x-h) is horizontal shift h units rightwards.
f(x+h) is horizontal shift h units leftwards.
So,
The transformation <u>sin(x)-7</u> results in a vertical shift down.
The transformation <u>sin(x+7)</u> results in a horizontal shift left.
The transformation <u>sin(x)+7</u> results in a vertical shift up.
The transformation <u>sin(x-7)</u> results in a horizontal shift right.

Answer:
22 hours
Step-by-step explanation:
Ken saves 90% of his earnings.
So, he must earn
270/x =90/100
90x=270*100
90x=27,000
x=27000/90
=300
x=$300 to save $270
For starting 10hours, Ken earns $8 per hour so he earns total
$8*10 hours=$80
Now, Ken has to earn remaining
$220 at a rate of $10/hour, he must work for at least
$220/$10
=22hours
Because he was impatient? he already knew how much he weighs?
