Answer:
240x + 75, $795 for 3 days
Step-by-step explanation:
$75 is not affected by the number of days she will be there, meanwhile, hotel and meal costs are. So, we will use x to represent the number of days and create an equation.
210x + 30x + 75
Then we can combine like terms
240x + 75
Using our new equation, we can solve for the total cost of 3 days.
240(3) + 75 = 795
3 days will cost $795

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.
