Y = ln {[sin(x)]^2}
use the chain rule
y' = 1 /[sin(x)]^2 * 2sin(x)*cos(x) = 2cos(x) / sin(x) = 2 cot(x)
Answer: 2 cot(x)
85/100
17/20 when simplified
The cost will be <u>$20.40</u>
<h3>
EXPLANATION</h3>
10% of $28 = $2.80
10% x 2 = $5.60 = 20%
$5.60 + $2 = $7.60
$28 - $7.60 = <u>$20.40</u>
Hope this helps!
The value in the 10 digits place is 6, because the tenths place is like a centimeter, and the digit in the hundreds place, is 6 again, because it is 10 times greater than the tenths place.
The top line tells you this two figure is similar.
What does this mean? Similar figures have the exact same corresponding angles and proportionate sides.
You can find their side ratio with 38 and 15.2.
38 ÷ 15.2 = 2.5
To find x, use 55 ÷ 2.5 and you get 22 as your answer.
