Step-by-step explanation:
the union of two sets is a new sets that contains all of the elements that are in at least one or two sets and written as (A U B)
while intersection of two sets is a new set that contains all of the elements in both sets and written as (A n B)
Yes you take 3 times 4 and receive 12 and 5 times 4 and receive 20
Answer:
Step-by-step explanation:
1. Given the integral function
, using trigonometric substitution, the substitution that will be most helpful in this case is substituting x as
i.e
.
All integrals in the form
are always evaluated using the substitute given where 'a' is any constant.
From the given integral,
where a = 7 in this case.
The substitute will therefore be 
2.) Given 

cross multiplying

3.) Rewriting the given integral using the substiution will result into;


Answer:
61°
Step-by-step explanation:
We have many angles and are asked to find angle number 4.
Looking at the picture, if we take a look at the angle across (mirrored) from 4, we see that it lists being 61 degrees, since that angle is a complete mirror of angle 4. Angle number 4 is 61°
