Answer:
∫ xe³ˣ dx
Step-by-step explanation:
The first integral can be solved with u substitution (u = ln x).
The third integral can be solved with a Pythagorean identity (cot²x = csc²x − 1).
The fourth integral can be solved with a power reduction formula (cos²x = ½ + ½ cos(2x)).
Only the second integral requires integration by parts.
B. 75.
Explanation: You're more likely to get 75 as the answer because it's in the middle of the symmetric distribution. The equation for the mean average is
sum of all numbers / how many number there are. And at the middle is where all the averages are.
Answer:
Surface area of the figure = 1,296π km²
Step-by-step explanation:
Given figure is a sphere;
Given:
Radius of sphere = 18 km
Find:
Surface area of the figure
Computation:
Surface area of the figure = Surface area of sphere
Surface area of sphere = 4πr²
Surface area of the figure = 4πr²
Surface area of the figure = 4π(18)²
Surface area of the figure = 4π(324)
Surface area of the figure = 1,296π km²
