Answer:
Option A is correct.
Step-by-step explanation:
The first step in the construction of a square inscribed in a circle is to draw a diameter of the circle.
Then we have to draw perpendicular bisector of the diameter using a compass.
Therefore, the perpendicular bisector will be another diameter of the circle and both the diameters will meet at the center of the circle.
Now, join the points with straight lines in order where the two diameters meet the circle. And finally, we will get a square inscribed in the circle.
Hence, option A is correct. (Answer)

Here is the work I did. I used the quadratic formula. Sorry about my bad handwriting.
Answer:
B
Step-by-step explanation:
From the statement, we are given a function that shows the number of cell tower users f(x) after x years, from the year 2010 to 2019, so, to solve the problem, we need to remember that the domain is equal to all the values that the variable (x for this case) could take making the function itself exist.
So, the given function is a function of years, and we know that "x" represents the years from 2010 (starting value), to 2019 (ending value) meaning that the domain is located between those two values.
Hence, the correct option is:
B. 0 ≤ x ≤ 5,000
FOIL is a mnemonic rule for multiplying binomial (that is, two-term) algebraic expressions.
FOIL abbreviates the sequence "First, Outside, Inside, Last"; it's a way of remembering that the product is the sum of the products of those four combinations of terms.
For instance, if we multiply the two expressions
(x + 1) (x + 2)
then the result is the sum of these four products:
x times x (the First terms of each expression)
x times 2 (the Outside pair of terms)
1 times x (the Inside pair of terms)
1 times 2 (the Last terms of each expression)
and so
(x + 1) (x + 2) = x^2 + 2x + 1x + 2 = x^2 + 3x + 2
[where the ^ is the usual way we indicate exponents here in Answers, because they're hard to represent in an online text environment].
Now, compare this to multiplying a pair of two-digit integers:
37 × 43
= (30 × 40) + (30 × 3) + (7 × 40) + (7 × 3)
= 1200 + 90 + 280 + 21
= 1591
The reason the two processes resemble each other is that multiplication is multiplication; the difference in the ways we represent the factors doesn't make it a fundamentally different operation.
