Answer:
28.9
Step-by-step explanation:
Using cosine, we get the equation cos(21)=x/31. Solving cos(21), we get about 0.933. Then we multiply by 31 to get about 28.9.
4 x 225 = 900
17500 / 900 = 19.44

Answer:
d. parabola, 0°
Step-by-step explanation:
y² + 8x - 0
y² = -8x
Where x = cos t , y = sin t
Sin² t = -8 Cos t
1 - Cos² t = -8 Cos t
- Cos² t + 8 Cos t + 1 = 0
t = 2лπ ± (3 + √10) , л∈Z
Angle of rotation
I'm assuming that each price copied twice, since 5.225.22 isn't a number.
To find the percent, divide the tip by the meal cost:
5.22 ÷ 29 = 0.18 = 18%
Jerry left an 18% tip.
To find the total cost of the meal, add the tip and the meal cost:
5.22 + 29.00 = 34.22
The total cost if the meal, including tip, was $34.22.
