Answer:
6.0
Step-by-step explanation: It is 6.0 because 0.6 is a decimal number and 6.0 is a whole number and can I be brainliest please
Answer:
At x= 20.10723974, both f(x)=g(x)
Step-by-step explanation:
f(x) = 300(1-0.04)^x = 300(0.96)^x
g(x) = 60(1+0.04)^x = 60(1.04)^x
now equate both of them and calculate x
300(0.96)^x = 60(1.04)^x
5(0.96)^x = (1.04)^x
ln(5) + x ln(0.96) = x ln(1.04)
x={ln(5)}/{ln(1.04)-ln(0.96)}
x= 20.10723974
The rate of the boat in still water and the rate of the current will be 25 miles per hour and 5 miles per hour.
<h3>What is speed?</h3>
The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.
We know that the speed formula
Speed = Distance/Time
A boat travels upstream for 60 miles in 3 hours and returns in 2 hours traveling downstream in a river.
Then the speed upstream will be
v₁ = 60 / 3
v₁ = 20 miles per hour
Then the speed downstream will be
v₂ = 60 / 2
v₂ = 30 miles per hour
Then the rate of the boat in still water and the rate of the current will be
The rate of the boat in still water will be
⇒ (v₁ + v₂) / 2
⇒ (20 + 30) / 2
⇒ 50 / 2
⇒ 25 miles per hour
The rate of the current will be
⇒ |v₁ - v₂| / 2
⇒ |20 - 30| / 2
⇒ 10 / 2
⇒ 5 miles per hour
Then the rate of the boat in still water and the rate of the current will be 25 miles per hour and 5 miles per hour.
