Answer:
$25.80
Step-by-step explanation:
Find the cost of the meal with the sales tax:
20 x 0.075 = 1.5
Add the sales tax to the total
20 + 1.5 = 21.50
Find the tip:
21.5 x 0.2 = 4.3
Add the tip to the total cost so far:
21.50 + 4.30 = 25.80
A recursive sequence is a sequence of numbers whose values are determined by the numbers that come before them in the sequence.
We’re given a sequence whose (n + 1)-th term f(n + 1) depends on the value of the n-th term f(n), specified by the recursive rule
f(n + 1) = -4 f(n) + 3
We’re also given the 1st term in the sequence, f(1) = 1. Using this value and the recursive rule, we can find the next term f(2). (Just replace n with 1.)
f(1 + 1) = -4 f(1) + 3
f(2) = -4 • 1 + 3
f(2) = -1
We do the same thing to find the next term f(3) :
f(2 + 1) = -4 f(2) + 3
f(3) = -4 • (-1) + 3
f(3) = 7
One more time to find the next term f(4) :
f(3 + 1) = -4 f(3) + 3
f(4) = -4 • 7 + 3
f(4) = -25
This question uses the concept of the division.
Vivi, the band drummer, burns 765 calories in 3 hours. And she burns these calories at the same rate. Which means she burns the same amount of calories per hour.
Thus, the set up equation for this question will be:
Energy burnt in 3 hours=756 calories
Therefore, Energy burnt in 1 hour = 
Calories.
Thus, the required answer is that Vivi burns 252 Calories of energy per hour while drumming.
