A.
2.718... between 2 and 3
2 = √4 and 3 = √9
So, 2.718... between √4 and √9 [√4 < e < √9]
b.
π = 3.1415...
3.1415... between 3 and 4
3 = √9 and 4 = √16
So, 3.1415... between √9 and √16 [√4 < π < √9]
Answer:
F = 100 + 0.1d
Step-by-step explanation:
- Initial charge is $100
- Price for climbing 3000 m = 400
<u>Then equation to find a fee per vertical distance:</u>
- 100+3000x = 400
- 3000x = 300
- x = 300/3000
- x = $0.1 per/m
So the fee for climbing vertical distance is $0.1 per meter.
- Vertical distance = d m
- Total cost = F
<u>Then, required equation is:</u>
R = 2x + 9y [ Given ]
When,
★ Substituting the values in the above equation
=> 13 = 2x + 9 × 3
=> 13 = 2x + 27
=> 13 - 27 = 2x
=> -14 = 2x
=> x = -14/2
=> x = -7
X=12
-5+17=12 - this is the quickest way to solve an easy equation like this
Absolute value equations have more than one solution because when the answer is in abs. value, it is positive, so there could be a negative answer and it would still be positive. For example |-5|=5 and |5|=5 as well.
4+|2x|=-1 would have no solution because you cannot have the equation equal a negative since the 2x is in absolute value.
