To understand the stacking of cups, start with the height of one cup plus its lip's height. Following that, continue to add the height of each lip until the desired total height is reached. Thus, the total number of cups needed is 19.
The piece-wise function can be expressed as follows: The base charge for renting the vehicle is $35 per day. If the car is rented for three days or fewer, there’s an insurance surcharge of $10 per day. For rentals over three days, the daily insurance cost drops to $5. Let’s denote the number of days as x. Accordingly, we have: For x ≤ 3, f(x) = 35 × x + 10 × x = x × (45) For x > 3, f(x) = 35 × x + 5 × x = x × (40). Therefore, the charge for renting the vehicle for three days or less is 45·x, and for rentals longer than three days is 40·x.
To properly complete the square, divide the b value by 2 and then square that result. For instance, if b equals 4, you would first halve it to get 2, and the square of 2 would give a result of 4.
