Answer:</h3><h3>cos(-t) = -4/9</h3><h3>sec(-t) = -9/4</h3>
Explanation:
Since cosine is an even function, we can say cos(-t) = cos(t) for all values of t. So this explains why cos(-t) = cos(t) = -4/9. No change happens.
To find the secant value, we apply the reciprocal. This is because sec = 1/cos. So that's how -4/9 flips to -9/4.
If the change in the number of pounds is p, the change in the cost will be $11c.
This is because each pound costs $11.

Answer:
Step-by-step explanation:
By "today" I think it means like times of pandemics like we are in right now. Technology is a debatable topic. People say it's good, but others say it's bad. Although, in times where you have to lock down for a week to 2 weeks if you get sick to prevent contamination, technology in this case could be useful. Communication is a major thing that technology helps with. You can't go visit your grandma if you're feeling bad, but maybe if you go on a one on one call and you tell your grandma how to start a video call, you both can communicate that way and share information.
