A country's population in 1995 was 164 million. in 2001 it was 169 million. estimate the population in 2015 using the exponentia
Vaselesa [24]
1995.          164 million
2001.          169 million
t = 2001 - 1995 = 6
169 =164 *  p^{6}
 p^{6} = \frac{169}{164}= 1.0304878 \\  p =  \sqrt[6]{1.0304878}
p = 1.00502
t 1 = 2015 - 2001 = 14
f ( t1 ) = 169 * 1.00502^{14}
f (t1) = 169 * 1.0762 = 181.27
Answer: a country´s population in 2015 will be 181 million.

10. A 266-hp output is required for an engine. If there is a 5% loss of power, what amount of input
marta [7]

Answer:

Amount of input horsepower needed is 279.3 hp.

Step-by-step explanation:

if there is a loss of power of 5% the base horsepower will need to be increased by same percentage so that same amount of power can be delivered.

Now to calculate 5% of 266 hp, we can write

266 ×\frac{5}{100} = 13.3 hp

Now to deliver same amount of power we will have to add 5% of 266 hp to its actual power.

So real base power which is needed to deliver 266hp output even at a loss of 5% will be = (266+13.3) hp = 279.3 hp

To know more about horsepower and percentage problem:
