Answer:
Constant of Proportionality is 50.
Step-by-step explanation:
Albatross can fly 400 kilometers in 8 hours.
'd' represents the distance and 't' represents the number of hours.
The equation represents the relationship between the distance and time.
Now, in the equation shown above 50 is the constant of proportionality, and 50 represents the rate of change of distance with time.
The constant of proportionality tells us the rate of change between two variables.
So for every 1 hour of time the distance covered is 50 kilometers.
Answer:
(b) 1
Step-by-step explanation:
To differentiate we will need the product rule:
.
We have , so the following equation is true by the transitive property:
By subtraction property we have:
Since , then we can divide both sides by
:
This implies is constant.
So we have that where
is a real number.
Since and
, then by transitive property
.
So .
Checking:
So the following conditions were met.
