1/2 = cos(2*t)sqrt(3) /2 = sin(-2*t)find tfind the time derivative of x(t), y(t)(-2sin(2*t) , -2cos(2*t) )plug in the t you found to find the velocity vector.
Answer:
The tip is greater than 20 percent
Step-by-step explanation:
The price of the pizza is 12.50
If you give a 20% tip
tip = original price times tip rate
tip =12.50* 20%
= 12.50 *.20
= 2.50
He gives the driver 15.50
15.50 -12.50 = 3 dollars which is the tip
3 > is greater than 2.50
The tip is greater than 20 percent
