Answer:

1/4

Step-by-step explanation:

The formula is y2-y1 over x2-x1.

(Remember that or another problem like that)

(3, 4) (-5,2)

x1 y1  x2 y2

We would do: 2-4 over -5-3

2-4=-2

-5-3=-8

Your answer would be: -2/-8, which is simplified to 1/4 because when you divide two negative numbers, you get a positive.

In how many ways can a president, vice president, secretary,
valentinak56 [21]

Answer:

120 ways

Step-by-step explanation:

This can be solved through analytical combination.

First, select the president; this implies selecting one person out of five people, which is in 5 ways.

Secondly, select the vice president, this implies selecting one person out of four people, since one position has been taken by the president already leaving only four people which is in 4 ways

Thirdly, select the secretary, this implies selecting one person out of three remaining people, which is in 3 ways

Lastly, select the treasurer, this implies selecting one person out of two remaining people, which is in 2 ways

Therefore, ways by which a president, vice president, secretary,  and treasurer can be elected is

5 x 4 x 3 x 2 = 120 ways

in the given figure, AB//PQ//CD. AB = x units. CD = y units and PQ = z unites. Prove that 1/x + 1/y = 1/z
Arlecino [84]
12. ∆ABD is similar to ∆PQD, so
   QD/z = BD/x
Likewise ∆CDB is similar to ∆PQB, so
   QB/z = BD/y

Since QD + QB = BD, you have
   QD/z + QB/z = BD/x + BD/y
   BD/z = BD/x + BD/y
Dividing by BD gives the desired result:
   1/x + 1/y = 1/z


13. Triangles ABD, BCD, and ACB are all similar. This means
   AB/AC = AD/AB
   AB² = AC×AD = (4 cm)×(9 cm)
   AB² = 36 cm²
   AB = 6 cm
and
   BD/CD = AD/BD
   BD² = CD×AD = (5 cm)×(4 cm)
   BD² = 20 cm²
   BD = 2√5 cm

FLAGPOLE Julie is 6 feet tall. If she stands 15 feet from the flagpole and holds a cardboard square, the edges of the square lin
Soloha48 [4]

Answer:

44 ft

Step-by-step explanation:

Given: Julie is 6 feet tall

           She stands 15 feet from the flagpole.

           The edges of the square line up with the top and bottom of the flagpole.

Lets assume the height of flagpole be "h".

As given, the edges of the square line up with the top and bottom of the flagpole.

∴ Angle and base of triangle are same then ratio of corresponding sides are also equal.

Now, finding the height of flagpole by using tangent rule.

we know, tan\theta= \frac{Opposite}{adjacent}

Remember, both the angle are equal.

∴ Ratio of opposite and adjacent leg for both right angle triangle= \frac{6}{15} : \frac{h-6}{15}

We can put it; \frac{6}{15} = \frac{15}{h-6}

Solving the equation now

⇒ \frac{6}{15} = \frac{15}{h-6}

Multiplying both side by 15

⇒6 = \frac{15\times 15}{h-6}

Multiplying both side by (h-6)

⇒ 6\times (h-6) = 15\times 15

Distributive property of multiplication

⇒ 6h-36= 225

Adding both side by 36

⇒6h= 225+36

Dividing both side by 6

⇒h= \frac{261}{6}

∴ h= 43.5\ feet \approx 44 feet

Hence, the height of flagpole is 44 feet.
