Answer:
88
Step By Step
Step-by-step explanation:
An arithmetic sequence is defined as
an=a+d(n-1) where an=nth term, a=initial term, n=term number, and d=common difference
For sequence 1,4,7... a=1 and d=4-1=7-4=3 so
an=1+3(n-1)
an=3n-2, so the 30th term is
an=3(30)-2
an=88
The answer would x=-1 for this question
Answer:
Step-by-step explanation:
We have been given a indefinite integral 
. We are asked to find the indefinite integral.
We will use partial fraction formula to solve our given problem.
Using difference rule of integrals, we will get:
Now, we need to use u-substitution as:
Let 
.
Substitute back these values:
Let us add a constant C.
Therefore, our required integral would be .
Answer:
7(x times y)
Step-by-step explanation:
Product means multiply, so it wants you to multiply two numbers and multiply THAT by 7. So we will use two variables, in this case, I will use x and y. X times y. 7 Times that.
