Answer:
Step-by-step explanation:
A polynomial is in its standard form when arranged in descending order based on the variable involved.
Looking at the provided polynomial
- s is presented in descending powers
- r is in ascending order
Thus, the first term of the polynomial should meet these criteria:
- Power of r is less than 2
- Power of s is greater than 4.
The following meets these requirements:
Answer:
According to the map, the length of the canal is 16.4 centimeters.
Step-by-step explanation:
If the real length of Panama Canal = 20 kilometers
and the canal's length on the map = 4 centimeters
Then, the scale factor is 
= 
= 
If the actual length of the Panama Canal = 82 kilometers
The length of the canal on the map = Actual length × Scale factor
= 
= 16.4 centimeters
So, the canal's length on the map is 16.4 centimeters.
Answer:
The charge for the first three hours is $4 per hour.
Subsequently, the rate decreases to $2 per hour until the sixth hour.
Between the sixth and tenth hours, the cost is reduced further to $1 per hour.
The maximum charge for renting the bike is $30.
Step-by-step explanation:
The incline on the graph indicates the hourly rate for the bike rental.
During the initial three hours, the rental fee rises by $4 for each hour.
From the third to the sixth hour, the graph’s slope indicates a rate of $2 per hour for the rental.
The charge drops to $1 per hour from the sixth to the tenth hour.
After the tenth hour, the price, P, remains constant. The highest fee for the bike rental is $30.
The least number of times that two planes can cross is zero, since parallel planes do not intersect. A good example would be a floor and a ceiling, which run parallel, hence they do not meet. Conversely, if two planes occupy the same space, they can intersect at infinitely many points, as could happen with a line within that plane.
