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.
C . 100 Times Greater
Then with the magnitude being 3 , It will be 1,000 times a standard earthquake .
Answer:
B is the correct answer
Step-by-step explanation:
Angles 1, 2, and 3 added together should make 180 degrees.
So, if angle 2 is 70 degrees, you subtract 70 from 180 (180-70=110) and you're left with 110 degrees.
Angle 1 and 3 add together should make 110 degrees which makes B the only true statement.
Answer:
70, 140, 280, 350
Step-by-step explanation:
Obviously, it must have the factors 2, 5, 7 as a minimum, so the smallest value is 2×5×7 = 70.
Any of these primes can be added to the product. In increasing order, the smallest additional factors will be 2, 4, 5, 7, 8, 10, ...
So, the four smallest numbers with prime factors of 2, 5, and 7 are ...
70 = 2·5·7
140 = 2²·5·7
280 = 2³·5·7
350 = 2·5²·7
