Answer:

Demand theory is an economic principle relating to the relationship between consumer demand for goods and services and their prices in the market. ... As more of a good or service is available, demand drops and so does the equilibrium price.

Demand theory describes the way that changes in the quantity of a good or service demanded by consumers affects its price in the market, The theory states that the higher the price of a product is, all else equal, the less of it will be demanded, inferring a downward sloping demand curve.

A person's heartbeat is 88 beats per minute. If his/her heart beats 3.1e9 times in a lifetime, how long (in whole years) does th
Anit [1.1K]
We can solve this problem by the rule of three.

88 beats-------------------1 minute
3.1*10⁹ beats------------    x

x=(3.1*10⁹ beats * 1 minute) / 88 beats=35227272.73 minutes.

Now, we express this amount of time in years.

1 year=365 days
365 days=365 day*(24 hour/1day)*(24 hour /1day)*(60 minutes /1hour)=
=525600 minutes.

525600 minutes----------------------1year
35227272.73 minutes----------------x
 
x=(35227272.73 minutes * 1year) / 525600 minutes=67.0229 years
≈ 67 years.

Answer:this person can live 67 years.

Answer:

\frac{ - 2 {x}^{2}  + 19x   + 3 }{3 {x} (4x^{2}     -  9 )}

Step-by-step explanation:

\frac{5}{6 {x}^{2}  + 9x}  +  \frac{1}{2x - 3}  -  \frac{2}{3x}  \\  \\  =  \frac{5}{3x(2 {x}   + 3)}  +  \frac{1}{2x - 3}  -  \frac{2}{3x}  \\  \\ =  \frac{5(2x - 3) + 1 \times 3x(2x + 3)}{3x(2 {x}   + 3)(2x - 3)}  -  \frac{2}{3x}  \\  \\  = \frac{10x - 15 + 6 {x}^{2}  + 9x}{3x((2 {x} ) ^{2}     -  {3}^{2} )}  -  \frac{2}{3x} \\  \\  = \frac{6 {x}^{2}   + 19x - 15}{3x(4x^{2}     -  9 )}  -  \frac{2}{3x} \\  \\  = \frac{3x(6 {x}^{2}   + 19x - 15) - 2 \times 3x(4x^{2}     -  9 )}{3x(4x^{2}     -  9 ) \times 3x}  \\  \\  = \frac{18{x}^{3}   + 57 {x}^{2}  - 45x - 24x^{3}      + 54x }{3x(4x^{2}     -  9 ) \times 3x}   \\  \\ = \frac{ - 6 {x}^{3}  + 57 {x}^{2}   + 9x }{9 {x}^{2} (4x^{2}     -  9 )}  \\  \\ = \frac{ 3x(- 2 {x}^{2}  + 19x   + 3) }{9 {x}^{2} (4x^{2}     -  9 )}  \\  \\  \huge \orange{ \boxed{= \frac{ - 2 {x}^{2}  + 19x   + 3 }{3 {x} (4x^{2}     -  9 )}  }}
