Answer:
Courtney and her family traveled 14 miles in Mr. De Palma's cab from the airport to the hotel.
Step-by-step explanation:
The total amount of the ride, including tip, was $42.00. Since this amount represents exactly eight times the amount that was received as a tip, 42/8 is $5.25, which is the cost of the tip. The other flat rates associated with the trip is the $3.15 for entry and $1.75 for each additional passenger (1.75 x 3=5.25). Once you subtract these fees from the total amount, $42 - $5.25 (tip) - $5.25 (additional passengers) - $3.15 (entry) = $28.35. Since Mr. De Palma charges $0.45 for every two-ninths of a mile, you take the revised total 28.35/.45 = 63. Since 63 represents the amount for every two-ninths of a mile, you need to multiply this amount by 2/9 to get your total amount of miles, or 63 x 2/9 = 14.
Answer: Hello mate!
you know that the equation is (or at least i think this is):
p(t) = 800 + 9t/90 + t^2
You want to know the "rate of change" after 6 hours.
We know that the rate of change is the derivative of P(t) with respect to t; this is
now we want the rate of change when t = 6, then we replace t by 6 in the derivate equation:
so the rate of change after 6 hours is 12.9
where 
If the equation is wrong ( because you write P(t) = 800 1 + 9t 90 + t2, and i don really know how to iterprete it) tellme and we can do the derivate again :D
Answer:
A
Step-by-step explanation:
I think you are in geometry I learned this a little back...
It's hard to explain but basically one side is just (n) another is (n(square root sign))and another is (2n.)
So the answer Is a because in this case (n) is 4
