Let $\overline{AB}$ and $\overline{CD}$ be chords of a circle, that meet at point $Q$ inside the circle. If $AQ = 6,$ $BQ = 12$,

Cloud [144]

Answer:

Step-by-step explanation:

The products of chord lengths are the same for the intersecting chords:

AQ×BQ = CQ×DQ

6×12 = CQ×(38 -CQ)

This gives a quadratic in CQ:

CQ² -38CQ +72 = 0 . . . . . write in standard form

(CQ -2)(CQ -36) = 0 . . . . . factor the quadratic

CQ = 2 or 36 . . . . . . . values of CQ that make the factors zero

The minimum length of CQ is 2 units. (DQ will be 36.)

Select the pair of slopes that are the slopes of perpendicular lines.

agasfer [191]

<h3> $\frac{3}{4}\ and\ \frac{-4}{3}$ are the slopes of perpendicular lines</h3>

Solution:

We know that,

Product of slope of a line and slope of line perpendicular to it is always equal to -1

Option 1

$\frac{1}{2}\ and\ 2$

$Product = \frac{1}{2} \times 2 = 1$

Thus, these are not the slopes of perpendicular lines

Option 2

$\frac{3}{4}\ and\ \frac{-4}{3}\\\\Product = \frac{3}{4} \times \frac{-4}{3}\\\\Product = -1$

This option satisfies the slopes of perpendicular lines

Option 3

$\frac{-2}{5}\ and\ \frac{-5}{2}\\\\Product = \frac{-2}{5} \times \frac{-5}{2} = 1$

Thus, these are not the slopes of perpendicular lines

Option 4

2 and 2

Product = 2 x 2 = 4

Thus, these are not the slopes of perpendicular lines

My answer was 16, so i thought as a fraction it would 16/100, but i think its 1/6 in the correct way, i dont really know.

larisa [96]

Answer: You're right.

Step-by-step explanation: There are only 6 parts to a die. so the change of landing on 6 would be 1/6, bc there's only 1-6 once.
