Answer: the price of the next model is $35371
Step-by-step explanation:
The cost of the current model of the car is $31,000
The next model of sports car will cost 14.1% more than the car model. This means that the amount by which the cist of the current model of the car will increase is
14.1/100 × 31000 = 0.141 × 31000 =$4371
The price of the next model of the car would be the sum of the previous model's price and the increase in price. It becomes
31000 + 4371 = $35371
Answer:
circle centered at (0,-1) and radius 4.
Step-by-step explanation:
The equation of a circle of radius r, with center is (a,b) is
(x-a)^2+(y-b)^2=r^2.
x^2+(y+1)^2=4^2=(x-0)^2+(y-(-1))^2=4^2 so that a=0, b--1 and r=4.
