1. If y<span>ou have jogged 5 miles from the park at a rate of r miles per hour, then the time you need to do this is
hours (
, where S is distance, v-speed and t-time).
</span>
2. W<span>hen you run back to the park, your average speed increases by 1 mph and become r+1 mph.
</span>
3. I<span>t takes
hours to jog 5 miles back to the park</span>
4. T<span>he total jogging time T is
hours.</span>
<span />
5. If you jogged away from the park at an average speed of 4 miles per hour, then r+1=4 and r=3. The expression
will take look
<span>
hours.</span>
When we factor in the remainder, we would round up. So your answer is 12 pages
2 parrots
6-2=4 canaries
4+1=5 goldfish
5-4=1 turtle
2+4+5+1= 12 pets
Answer:
Domain is all real numbers.
Step-by-step explanation:
Given:
The function is given as:
A function is like a machine which gives an output for a given output.
The input to a function is called its domain. The domain is the set of all possible values for which the function is defined. The domain is represented by the independent variable 'x'.
The output of the function is the function value for the given 'x'. It is represented by 'y' or 'f(x)'.
So, the domain must include only those values which give a definite value for .
Here, the given function is a cubic function. A cubic function is one which has the highest power of 'x' as 3. A cubic function is defined for all real values of 'x'.
Therefore, the domain of the given function is all real values.
