No. If you solve it for $y$ , you have

$y=\pm\sqrt{x^2+100}$

So, given a certain value for $x$ , say $x=0$ , you have

$y=\pm\sqrt{100}=\pm10$

So, you're associating two y-values for each x value. This implies that this is not a function.

In quadrilateral ABDC, AB ∥ CD. Which additional piece of information is needed to determine that ABDC is a parallelogram? AB ≅

siniylev [52]

For any quadrilateral to be a parallelogram

i) either both the pairs of opposite sides must be equal

ii) Both the pairs of opposite sides must be parallel

iii) Opposite pairs of angles must be equal

iv) Diagonals must bisect each other.

v) A pair of opposite sides must be parallel and equal

Here we are already given that AB || CD

So either we should be given that AD || BC

or we must be given that AB = CD

Here it is given AB = CD as an option.

So Option A) or the first option is the right answer that AB ≅CD is needed to prove ABCD is a parallelogram.

You are selling lemonade for $1.50, a bag of kettle corn for $3, and a hot dog for $2.50 at a fair. Write and simplify and expre

denpristay [2]

<span>You are selling the following items.
=> lemonade = $1.50
=> kettle corn = $3
=> hotdog = $2.50
=> p = number of people

Now, we need to write the expression of this given equation:
=> Amount = p(1.50 + 3 + 2.50) or Amount = p(1.50) + p(3) + p (2.50)
In where p is the number of people who will buy your food and will be multiplied to the amount of each food you’re selling to be able to get the total amount of money you will have.

Answer:

C. 5 × 3

Step-by-step explanation:

The order of a matrix is the number of rows and columns that a matrix has. Rows are listed first and columns are listed second. The matrix has 5 rows going across horizontally and 3 columns going down vertically.

So, the order of the matrix is 5 × 3.

Hope that helps.
