The answer is option D) r < 5 or r > – 1.
I'm going to graph each inequality below on a number line.
A) r > 5 or r > – 1.
The result is found just by joining those two intervals together. Actually that compound inequality only implies
r > – 1
which does not represent all real numbers.
—————
B) r > 5 or r < – 1.
Numbers between – 1 and 5 (including them) are not included in the union, so you don't have all real numbers represented there either.
—————
C) r < 5 or r < – 1.
Numbers that are greater or equal to 5 are not in the union. So it does not represent all real numbers.
—————
D) r < 5 or r > – 1.
Now all real numbers are included in the union. So this is the right choice.
Answer: option D) r < 5 or r > – 1.
I hope this helps. =)

The exponent of the power is 11 in scientific notation.
<h3>Given </h3>The numbers are;
The product of (9. 1 × 10^9)(7. 5 × 10^2)
<h3>What is scientific notation?</h3>Scientific notation is a method of expressing numbers in terms of a decimal number between 1 and 10, but not 10 itself multiplied by a power of 10.
To find the product of the given numbers follows all the steps given below.
The product of number is;
Hence, the exponent of the power is 11 in scientific notation.
