Answer:
$893.666 rounded to the nearest cent is $894.00
The number of angles equal the number of sides
The number of angles calculate: (n-2)x180°
(n-2)x180°=2700° |divide both sides by 180°
n-2=15 |add 2 to both siedes
n=13
Answer: 13 sides.
Mixed number : 4/5 + 8/9 = 76/45
Simplest form : 4/5 + 8/9 = 1 31/45
Step-by-step explanation:
So, I made both of the denominators the same then added the fractions together.
Step-by-step explanation:
the derivative of an inverse function is
1/f'(f^-1(x))
f'(x) = -6x²
f^-1(7) is solving the original function equation for x under the knowledge that y = 7
7 = 5 - 2x³
2 = -2x³
-1 = x³
=>
x = -1
f'(-1) = -6×(-1)² = -6×1 = -6
so,
(f^-1)'(7) = -1/6
