∆abc is isosceles, ab = bc, and ch is an altitude. how long is ac, if ch = 84 cm and m∠hbc = m∠bac +m∠bch?
Tems11 [23]
Given that <span>∆abc is isosceles and ab = bc, then m<bac = m<acb and m<hbc = 180 - m<bac - m<acb

Given that </span><span>m∠hbc = m∠bac +m∠bch, then m<hbc + m<bch = m<bac + 2m<bch

But m<hbc + m<bch = 90°, thus 90° = m<bac + 2m<bch

</span><span>Also, m∠bac + m∠ach = 90° ⇒ m<bac + 2m<bch = m<bac + m<ach ⇒ 2m<bch = m<ach

Since, Δabc is isosceles with ab = bc ⇒ m<bac = m<acb.

Also, m<acb = m<ach + m<bch ⇒ m<acb = 3m<bch = m<bac

</span><span><span>Since m<bch : m<ach = 1 : 2 ⇒ bh : ah = 1 : 2

Thus, bh:bc:ch=1:3:\sqrt{8}

Given that ch = 84 cm, then

\frac{bc}{ch} = \frac{bc}{84} = \frac{3}{\sqrt{8}}  \\  \\ \Rightarrow bc= \frac{3\times84}{\sqrt{8}} =63\sqrt{2}=ab

Now, ah= \frac{2}{3} (63\sqrt{2})=42\sqrt{2}

ac= \sqrt{ch^2+ah^2}  \\  \\ = \sqrt{84^2+(42\sqrt{2})^2}  \\  \\ = \sqrt{7056+3528} = \sqrt{10584}  \\  \\ =42\sqrt{6}

I have no clue what is even happening in this qs! help
Margarita [4]

Answer:

9

Step-by-step explanation:

median: The middle number after the numbers have been sorted into ascending or descending order.

Mean: The quotient of the numbers added together then divided by the amount of numbers.

So if 9 were the missing number the median would be 5 because in ascending order it would look like this:

1, 3, 5, 7, 9

and as you can see 5 is in the middle.

The mean would also be 5 because

1+ 3+ 5 + 7 +9 =25

and 25 divided by 5 equals 5

So therefore the missing number must be 9.

(Also it was obvious that they just added 2 to each number)

Which of the following give the highest future value is 6000000 is invested at 6% for 3 years​
Blababa [14]

Answer:

$5084745.76271

Step-by-step explanation:

Given data

Final amount= $6000000

Rate=6%

Time= 3 years

Now let us find the initial amount which is the principal

using the simple interest formula we have

6000000 = P(1+0.06*3)

6000000 =P(1+0.18)

6000000 =P*1.18

P= 6000000 /1.18

P=$5084745.76271

Hence the initial deposite is $5084745.76271
