31000 rounded to the nearest ten thousand

Answers

Answer 1

Answer: The 3 is in the ten thousands place so the number to the right of that tells you if you need to tound up or down. Anynumber 5 or higher then you round up. If lower than five you leave it alone.
So answer is slready rounded -

Answer 2

Answer: A number rounded to the nearest 10000, means that the last four digits of that number (on the left of the decimal point) are 0.
However, if the fourth-last digit to the left of the decimal point is 5 or greater, the number to the left of that is rounded to 1 number higher. For example, if you were rounding 145293 to the nearest 10000, it would be 150000.

However, the fourth-last digit to the left of the decimal point in this case is 1.
Therefore, 31000 rounded to the nearest 10000 is 30000.

We need to find the exponentialfunction for the given graph.

What are exponential functions?

A function whose value is a constant is raised to the power of the argument, especially the function where the constant is e.

Now, exponentialfunctions have a horizontalasymptote. The equation of the horizontal asymptote is y=0.

Horizontal Asymptote: y=0.

How is it that a square is a rectangle but a rectangle ins't a square?

Answers

beacuse A square by definition is a "plane figure having four equal sides." Rectangles' sides are not equal and hence cannot be a square.

A rectangle by definition is a "four-sided plane figure with 4 right angles" - which also implies that a square can be a rectangle because it is also a four-sided plane figure with 4 right angles...... hope this helps

The definition of a square is a plane figure with four equal straight sides and four right angles. The definition of a rectangle is a plane figure with four right sides and four right angles. To be a rectangle you just need four straight sides and four right angles, but to be a square all those sides have to be equal. Therefore, a square is a rectangle because it has four straight sides and four right angles, but a rectangle isn't a square (or not always) because it doesn't have four equal straight sides.
