Answer:

4n^2+3n+2

Step-by-step explanation:

9 24 47 78 117

 15  23

     8

8/2 = 4

=4n^2

9-4 = 5 (the minus value come from 4n^2 where n is the position where 9 lays)

24-16 = 8

47-36 = 11

so plus 3 every time so 3n

4n^2+3n for the first value is 7 so you need an extra 2

4n^2+3n+2

5.   What is an equation for the line with slope and y-intercept 9?  (1 point)
Semenov [28]
6.) y - (-3) = (1 - (-3))/(3 - 1) (x - 1)
y + 3 = (1 + 3)/2 (x - 1)
y + 3 = 4/2 (x - 1)
y + 3 = 2(x - 1) = 2x - 2
y = 2x - 2 - 3 = 2x - 5
y = 2x - 5

5) Lee's model airplane flies at 18 miles per hour. Lee took the plane to a field in windy weather. It took six minutes to fly 2
kap26 [50]

The wind is blowing at the rate of 4 miles per hour

<h3>Speed and distances</h3>

The formula for calculating speed is expressed as:

Speed = Distance/Time

Given the following parameters

Speed of airplane = 18 miles per hour

Speed in wind = 2.2 * 10  = 22 miles/hr

Speed of the wind = 22 - 18

Speed of the wind = 4mi/hr

Hence the wind is blowing at the rate of 4 miles per hour
