If you don't know the derivative of the inverse of sine, you can use implicit differentiation. Apply sine to both sides:

(true for <em>y</em> between -π/2 and π/2)
Now take the derivative of both sides and solve for it:




Answer:
x ≤ - 27
Step-by-step explanation:

A. n<1.3
-2.5n+8.7>5.45
subtract 8.7 from both sides
-2.5n>-3.25
divide -2.5 from both sides
(since you divided by a negative you flip the sign!!)
n<1.3
Answer:
1: 8a²
2: 9a²b²c²
Step-by-step explanation:
1: 48a³ ÷ 6a
48÷6 = 8
8a²
2: 72a³b⁴c⁵ ÷ 8ab²c³
72÷ 8 =9
9a²b²c²
Step-by-step explanation:
Convert the given value in cm into feet and inches.
<u>Use the unit rates:</u>
- 1 foot = 30.48 cm
- 1 inch = 2.54 cm
<u>Convert:</u>
- 170 cm = 170/30.48 feet = 5.58 feet (rounded)
- 170 cm = 170/2.54 inches = 66.93 inches
or
- 170 cm = 5 feet and 17.6 cm = 5 feet and 7 inches (rounded)
