PIT_PIT [208]

Answer with Step-by-step explanation:

We are given that:

Brennan has been playing a game where he can create towns and help his empire expand.

Brennan started with 5 villagers.

Each town he has allows him to create 1.15 times as many villagers.

i.e. after creating one town he gets 5×1.15 villagers

after creating 2 towns he gets  5×1.15×1.15 villagers

after creating 3 towns he gets  5×1.15×1.15×1.15 villagers

after creating n towns he gets 5*(1.15)^n villagers

Hence, after creating 15 towns he gets 5*(1.15)^1 villagers

                                                              ≈ 41 villagers

An equation to predict the number of villagers for any number of towns is:   Let number of towns be n

  Then number of villagers = 5*(1.15)^n

In triangle △ABC, ∠ABC=90°, BH is an altitude. Find the missing lengths.
shtirl [24]

Answer:

HC=\sqrt{3}

Step-by-step explanation:

Let HC=x, it is given that AH=3HC, then AH=3x.

Since, from the given figure, ΔABC is similar to ΔBHC and ΔABC is similar to ΔABH.

Therefore, ΔABH is similar to ΔBHC, hence using the similarity conditions,

\frac{HC}{BH}=\frac{BH}{AH}

\frac{x}{3}=\frac{3}{3x}

3x^{2}=9

x^{2}=3

x=\sqrt{3}

Hence, HC=\sqrt{3}.
