Determine the central angle and sum of exterior angles of an irregular nonagon
ololo11 [35]

Answer:

Step-by-step explanation:

You cannot find the exterior angles of any irregular nonagon. If it is a regular one, then you can. A regular nonagon has 9 sides and so 9 exterior angles all of which are equal to 360/9 = 40 degrees. The interior angle = 180 - 40 = 140 degrees.

The table below shows a pattern in the cost of renting a car based on the number of days rented. Car Rentals Number of Days (d)
andrezito [222]

The linear equation that describes the pattern in the cost of renting a car is given by:

  • D. c = 34d + 25

<h3>What is a linear function? </h3>

A linear function is modeled by:

y(x) = mx + b

In which:

  • m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
  • b is the y-intercept, which is the value of y when x = 0.

In this problem:

  • For each day, the cost of renting a car increases by 34, hence, the slope is of 34, and the equation is:

c(d) = 34d + b

When d = 4, c = 161, and this is used to find b.

c(d) = 34d + b

161 = 34(4) + b

b = 25

Hence, the equation is c = 34d + 25, and option D is correct.
