Answer:

The height of the jumping hill x = 189.3 m

Step-by-step explanation:

From Δ ABC

AB = x = height of the hill

∠A = 36° , ∠B = 90°

Thus ∠C = 180 - ∠A - ∠B

⇒ ∠C = 180 - 36 - 90

⇒ ∠C =  54°

From Δ ABC  

\sin 54 = \frac{AB}{AC}

\sin 54 = \frac{x}{234}

x = 0.809 × 234

x = 189.3 m

This is the height of the jumping hill.

While in Europe, if you drive 123 km per day, how much money would you spend on gas in one week if gas costs 1.10 euros per lite
Leona [35]
First, you drive 123km per day, and they ask for in a week.
There are 7 days in a week, we have to multiply 123 by 7, which equals 861.
=km per week 861
Now, we need to find out how much cost the gas. Gas cost 1.10 euros per-liter, and this problem wants us to assume that 1euro = 1.26 dollars.
 
So, we divide 1.10 by 1.26 which is 0.87.
=gas cost 0.87 per liter.

Next, this person goes 31.0 mi/gal per stop.
To get the answer we need to divide 861 the full distance in a week and divide it by how many stops nee to be made which is each 31 mi/gal.

So, 861/31 = 27.77 and now we times 0.87 by 27.77 to get gas cost.
=24.16

PLEASE HELP!!<br><br> which graph represents the function f(x) = -|x| - 2
Nonamiya [84]

Answer:

The graph on the far right

Step-by-step explanation:

The negative in front of the absolute value indicates that the parent function |x| has been reflected over the x-axis and points downwards. The negative 2 being added to this portion shows that there has been a vertical shift of two units downwards as well. Therefore, the graph on the far right is the correct graph.
