Response:
6.48
Detailed explanation:
The calculation required to determine the number of tiles for the border is presented below:-

Here,
The length measures 2.02 m
And the width is 1.22
Substituting these dimensions into the formula provided above
Consequently, the total number of tiles necessary to create the border is


= 6.48
Hence, to find the tiles required for the border, we utilized the aforementioned formula.
Answer:
The parametrization of the specified curve is 
Step-by-step explanation:
From the provided problem statement, we derive the function

When y = 5



Converting the above to a polar equation yields

Each tweet could cost anywhere from 1 to 140 pennies, which can be expressed as an inequality [1 ≤ x ≤ 140]. Since it's impossible to tweet 0 characters or exceed 140. If required in pounds, simply divide by 100. A) 1 ≤ x ≤ 140 B) The cost per character is a penny, and tweeting fewer than 1 character or more than 140 is not permitted.
