1) place the compass needle on the external point r.2) make the compass width greater than the distance from r to the given line.
3) draw an arc cutting the given line at two points.
4) mark and label the points of intersection p and q.
5) without changing the compass width, move the compass needle to q and draw another arc below the line crossing the previous arc.
6) move the compass needle to p and make an arc below the line.
7) mark and label the point of intersection s.
8) draw a line from the external point r to the point where the arcs intersect, s.
9) line rs is perpendicular to line pq and passes through the external point r.

Hi. I need help with these questions.<br> See image for question.<br> Answer 16 and 17
Irina-Kira [14]

Step-by-step explanation:

16.................................................

<h3>Given</h3>
  • Equation ax² + bx + c = 0
  • One of the roots is twice the other
<h3>To find</h3>
  • Show that 2b² = 9ac
<h3>Solution</h3>

Let the roots be p and q

<u>The sum and product of the roots:</u>

  • p + q = -b/a
  • pq = c/a

<u>The sum of the roots, considering p = 2q,</u>

  • p + q = 2q + q = 3q

And

  • 3q = -b/a ⇒ q = -b/(3a)

<u>The product of the roots, considering p = 2q:</u>

  • pq = 2q(q) = 2q²

And

  • 2q² = c/a

<u>Substitute q with -b/(3a)</u>

  • 2(-b/(3a))² = c/a
  • 2b²/(9a²) = c/a
  • 2b² = 9a²(c/a)
  • 2b² = 9ac

=================================================

17. .................................................

<h3>Given</h3>

Quadratic equation

  • ax² = bx + c = 0, with equal roots
<h3>To find</h3>
  • Show that b² = 4ac
<h3>Solution</h3>

<u>Equal roots means the discriminant is zero:</u>

  • D = √b² - 4ac
  • √b² - 4ac = 0
  • b² - 4ac = 0
  • b² = 4ac

10 - 2 (3x + 4) &lt; 11
Effectus [21]

Answer:

x > - \frac{3}{2}

Step-by-step explanation:

Given

10 - 2(3x + 4) < 11 ← distribute and simplify left side

10 - 6x - 8 < 11

2 - 6x < 11 ( subtract 2 from both sides )

- 6x < 9

Divide both sides by - 6, reversing the symbol as a result of dividing by a negative quantity.

x > \frac{9}{-6} ⇒ x > - \frac{3}{2}

The box plot shows the number of years during which 24 colleges have participated in a local college fair
Bond [772]
The boxplot provides the following information:
Minimum = 0
First quartile = 2
Median = 4
Third quartile = 7
Maximum = 9

The sum is 2+4+7+9 = 22
The unaccounted for participants is 24 - 22 = 2 (outliers).
Those who participated for 2 years or less is 2.
