Answer:
1. 2/21
2. 7/45
3. 9/26
4. 4/61
5. 3/29
6. 8/61
Step-by-step explanation:
I'll just explain number one, since you can do the same thing to solve all the others.
You start with 10 1/2. You can make this an improper fraction by multiplying 10 and 2, then adding one. This leaves you with 21/2. The reciprocal of a fraction is just the numerator and denominator of the fraction flipped. So, you get 2/21.
Hope this helps!

Answer:
x=4
Step-by-step explanation:
(2x+3)^2=121
2x+3=square root of 121
2x+3=11
2x=11-3
2x=8
x=4
(in a square all sides are equal therefore area =length ×width where length and width=2x+3)
Answer:
-100x=-100
x=1
Step-by-step explanation:
(simplifying the equation)
-100x-100=0
-100x=-100 they subtracted -100 from both sides
x=1 then divided by -100

Answer:
The integral diverges
Step-by-step explanation:
Consider the integral from 0 to infinity of
We can do this in parts
When we substitute limits infinity we find that the values become infinity
Hence the integral diverges
The given improper integral diverges
