Answer:

Step-by-step explanation:
the transverse axis is horizontal.
so its a horizontal hyperbola
Center is the origin so center is (0,0)
Equation of horizontal hyperbola is

Given a= 55000 and c= 81000
c^2 = a^2 + b^2
81000^2 = 55000^2 + b^2
subtract 55000^2 on both sides
b = sqrt(81000^2 - 55000^2)= 59464.27
now plug in the values

I believe it is x=55. I could be wrong lol
Answer:
The second one would be the answer.
Step-by-step explanation:
If you look at the model, it shows it on 125 going down to 90.
If she has $125 and she spends $35 on gas, you would subtract that from how much money she has.
125 - 35 = 90.
Feel free to let me know if you need more help. :)
First convert the equation in the form of <em>y= mx + </em><em>c</em>
The equation will be like = y = 6x-5
value of m = 6
The slope of perpendicular line will be = -1/m = -1/6
Answer: Terry should buy the half-liter of water that costs $2.11 because buying 200 litres here is cheaper.
Step-by-step explanation:
Terry is buying water and needs 22 liters. A half-liter of water costs $2.11. Using this information, 22 litres will cost:
= 22 ÷ 1/2 × 2.11
= 22 × 2 × 2.11
= $92.84
Also, A 200 -milliliter container of water costs $1.01. Using this information, 22 litres will cost:
= 22 × 1.01 ÷ 200/1000
= 22 × 1.01 × 1000/200
= 22 × 1.01 × 5
= $111.1
Based on this information, Terry should buy the half-liter of water that costs $2.11 because buying 200 litres here is cheaper.
