Find a ordered pair to represent a in the equation a=b+c if b= (6,3) and c =(-4,8)

Vilka [71]

Answer:

So ordered pair a is (2,11)

Step-by-step explanation:

We are given

a = b+c

and ordered pair b =(6,3) and ordered pair c =(-4,8)

Putting values of b and c in the given equation and adding x and y coordinates of b and c we can find ordered pair a.

a=(6,3)+(-4,8)

a =(6-4,3+8)

a =(2,11)

So ordered pair a is (2,11)

As John walks 16 ft towards a chimney, the angle of elevation from his eye to the top of the chimney changes from 30° to 45°. Id

levacccp [35]

ANSWER

The height is $22ft$

EXPLANATION

Let the height of the chimney be x.

$\tan(45 \degree) = \frac{x}{y}$

$1 = \frac{x}{y}$

$x = y$

$\tan(30 \degree) = \frac{x}{16+ y}$

$\frac{ \sqrt{3} }{3} = \frac{x}{16 + y}$

Cross multiply

$\sqrt{3} (16 + y) = 3x$

$16 \sqrt{3} + y \sqrt{3} = 3x$

Put

$y = x$

into the equation;

$16 \sqrt{3} + x \sqrt{3} = 3x$

Group similar terms:

$16 \sqrt{3}= 3x - x \sqrt{3}$

$16 \sqrt{3}= (3 - \sqrt{3})x$

$\frac{16 \sqrt{3} }{3 - \sqrt{3} } = x$

$x=21.856$

The height of the chimney to the nearest feet is 22
