Derive the equation and equate the derivative to zero.
dan/dt = -2n + 6 = 0
The value of n in the equation is 3. We substitute 3 to the original equation,
an = -(3)² + 6(3) - 7 = 2
The answer to this item is letter B.
Answer:
154
Step-by-step explanation:
Since its a circle, it will be 360 degrees, so then do 190+26=206, then do 360-206=154
Answer:
1.732i (complex form)
its weird, at high-school level complex shouldn't come, its considered mistake in the question. But the mathematically its all correct
Step-by-step explanation:
Answer: -14y
Step-by-step explanation:
Given parameters:
Number of sides of the regular body = 10
A decagon has 10 sides.
Unknown:
Sum of the measures of the interior angles = ?
Solution;
To find the sum of the interior angles of a decagon; use the expression below:
Sum of interior angles = (n - 2) x 180
where;
n = number of sides;
So,
Sum of interior angles = (10 - 2) x 180 = 1440°
The sum of interior angle of a decagon is 1440°
