You get the nearest whole number by rounding if the number is 5 or more you round up 4 or less round down...in this case you're rounding the decimal and the first number after the decimal is 4 so you round to....
If its what you are asking...
1) Expressions have no equals or inequality signs (ex. 5(6)^3 + 45).
2) Ordered comes as thus: 1, 1, 2, 4, 6, 10, 16, 26...
3) Comparisons have inequality signs( \geq , \leq, >, <) or Equality signs(=).
Answer: 3 minutes. I can't explain it. but your answer would be 3
1. The graph is a parabola.
2. The parabola opens up, because there's no negative number in front of 
.
3. The vertext is (5,-1), because of the vertex form.
This means that that -1 will be the least y-value used on the graph and the garph will open up from there.
The range is (-1, infinity) or { y | y > -1 }.
Answer:
C) To square a number, multiply the number by itself.
Step-by-step explanation:
A) is incorrect because square roots are made by multiplying the number to itself.
2 × 2 is the same as 2²
3 × 3 is the same as 3²
4 × 4 is the same as 4²
2² = 4
3² = 9
4² = 16
B) is incorrect because the inverse of squaring is finding the square root.
2² inverse is √4
3² inverse is √9
4² inverse is √16
D) is incorrect because perfect squares can be odd or even
A perfect square is a number made by squaring a whole number.
4, 9, 16, 25, 36, 49, 64, 81, 100, 121, and 144 are all examples of perfect squares.
