Reflection across y=3 in mathematics means that every point or object is mirrored over the line y=3. This results in the x-coordinate remaining the same, while the y-coordinate changes, following the formula (x, y) => (x, 2*3-y). It involves mirroring the points above and below the line y=3.
In mathematics, reflection across y=3 implies that every point or object on the coordinate plane is mirrored over the horizontal line y=3. Let's say you have a point (x,y), when it is reflected over y=3, the new point will remain at the same x position, but its y-coordinate changes. The formula for reflection is (x, y) => (x, 2*3-y). Therefore, if a point is above the line y=3, it will be reflected below it and vice versa. For example, if you have a point at (5,4), it will be reflected onto the point (5,2).

An integer is a whole number that's not a fraction, thus a positive integer for 45, would be 45.
Natural numbers are: 1, 2, 3, ....
Integer numbers are: ...., -2, -1, 0, 1, 2, ... (so it includes positive and negative natural number, and 0 )
Rational numbers are numbers which can be written in the form of a/b where a and b are integers. Example: 1/2, 3.5 (which is writable as 7/5) etc.
Irrational numbers are those real numbers which are not rational numbers.
Know that all natural numbers are integers, all integers are rational numbers. That means, natural numbers are not irrational.
We have to write an integer for: a deposit of $45 *
A deposit is positive, therefore the integer will be positive.

B. surface of a sphere.
C. side of a cone.
D. side of a box.
Answer:
40 in
Step-by-step explanation:
A= l x w
2 x 9 = 18
2 x 11 = 22
Then add together because the shape is together:
18 + 22 =
