The number √+2 can be written as: √2

The value of √2 is: 1.1442135.....

Rational number: A number is said to be rational, if it is in the form of p/q. Where p and q are integer and denominator is not equal to 0.

Irrational number: A number is irrational if it cannot be expressed be expressed by dividing two integers. The decimal expansion of Irrational numbers are neither terminate nor periodic.

31.693 Rounded to the nearest Hundredth ​
ioda

Hi there!  

»»————- ★ ————-««

I believe your answer is:  

31.69

»»————- ★ ————-««  

Here’s why:  

⸻⸻⸻⸻

  • '9' is in the hundredths place. The rounding is the digit to it's right, or '3'.
  • Since 3 is less than or equal to 4, we would round down.

⸻⸻⸻⸻

31.693 ≈ 31.69

⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.

Find the gradient of the line Joining the points p(-2,6) and Q(3,-2)​
Rudiy27

Answer:

-  \frac{8}{5}

Step-by-step explanation:

\boxed{gradient =  \frac{y1 - y2}{x1 - x2} }

(x₁, y₁) is the 1st coordinate while (x₂, y₂) is the 2nd coordinate.

Gradient of the line

=  \frac{6 - ( - 2)}{ - 2 - 3}

=  \frac{6 + 2}{ - 5}

=   - \frac{8}{5}
