from 2002 to 2012, the number of a particular make of cars sold at a dealership yearly declined to 500. The number is expected t

Alinara [238K]

To determine the number of cars that will be sold by the year 2020, we will use the equation,

N = (N1)(1 - r)^(t)

where N1 is the starting number of cars, r is the rate of the decrease, and t is the number of years from 2012. Substituting the konwn values,

N = (500)(1 - 0.028)^(8)
N = 398.38

The closest integer to the calculated value is 398. Thus, the answer is 398 cars.

Classify the limaçon represented by the equation r=(1/2)-(1/2)sin(theta)

babunello [35]

We know that

Limacons are in the form
r=a(+-)b*sin (theta) or r=a(+-)b*cos (theta)

in this problem
r=a(+-)b*sin (theta)
so
is symmetric to y axis
a=1/2
b=1/2
a/b=1---------> Cardioid (hearth shaped)

see the attached figure

the answer is the option
<span>A. Cardioid </span>
