<h3>Answer:</h3>

19 °F

<h3>Explanation:</h3>

The difference between 2 °F and -17 °F is ...

... difference = 2 °F - (-17 °F) = (2 +17) °F

... difference = 19 °F

_____

Subtracting a number is the same as adding it opposite. Subtracting -17 is the same as adding 17.

Find the coordinates of point which divides the line segment joining the points (a+b,a-b) and (a-b,a+b) in the ratio 3:2 interal
sasho [114]

Answer:

  • Coordinate of 0 = \bigg( \dfrac{5a-b}{5},\:\dfrac{5a+b}{5}\bigg)

Step-by-step explanation:

  • Let AOB be the line segment
  • Point 'O' divides the line segment into m:n = 3:2

Given:

  • Coordinate of a = (a+b, a-b)
  • Coordinate of b = (a-b, a+b)
  • Ratio = 3:2

ToFind:

  • Coordinate of 0 (zero)

Solution:

ATQ,

  • \dfrac{m}{n}=\dfrac{3}{2}
  • Coordinate of a = (x_{1}, y_{1})
  • Coordinate of b = (x_{2}, y_{2})

As we know that,

\implies\:\:x = \dfrac{mx_{2} + nx_{1}}{m + n}

\implies\:\:x = \dfrac{(a-b)3 + (a+b)2}{3+2}

\implies\:\:x = \dfrac{3a - 3b + 2a + 2b}{5}

\implies\:\:\red{x = \dfrac{5a - b}{5}}

Similarly,

\implies\:\:y = \dfrac{my_{2}+ny_{1}}{m+n}

\implies\:\:y = \dfrac{(a+b)3+(a-b)2}{3+2}

\implies\:\:y = \dfrac{3a+3b+2a-2b}{5}

\implies\:\:\red{y = \dfrac{5a+b}{5}}

Hence,

Coordinate of 0 is \blue{\bigg( \dfrac{5a-b}{5},\:\dfrac{5a+b}{5}\bigg)}

Height, h of the cone is 3V/πr²

Step-by-step explanation:

  • Step 1: Find formula for height.

Volume, V = 1/3 πr²h, where r is the radius and h is the height of the cone.

Cross-multiply to find formula for height.

∴ Height, h = 3V/πr²
