Answer:
Step-by-step explanation:
You are given two x and y pairs: (100,45) and (570,162.5)
First solve for the slope, m.
m = (162.5 - 45) / (570 - 100)
m = 117.5 / 470
m = 0.25
Not only is "m" the slope but it is the rate (dollars per minute) in the question. So it's 25 cents per minute to use the phone.
After imputing "m" the linear equation looks like this:
y = 0.25x + b
Use either point as (x,y) to solve for the y-intercept "b". I'll use (100,45)
45 = 0.25(100) + b
45 = 25 + b
45 - 25 = b
20 = b
Not only is "b" the y-intercept but it is also always the flat fee added on to linearly increasing cost questions like this.
Final equation is:
y = 0.25x + 20
Part B.) If 939 minutes are used. Just put that in for x and solve for y.
y = 0.25(939) + 20
y = 234.75 + 20
y = 254.75
Hey there!
6(3.14)^6
= 6(3.14^6)
= 6(3.14 * 3.14 * 3.14 * 3.14 * 3.14 * 3.14)
= 6(9.8596 * 9.8596 * 9.8596)
= 6(97.21171216 * 9.8596)
= 6(5,750.811583)
≈ 5750.81158328
Therefore, the answer should be:
5,750.81158328
Good luck on your assignment & enjoy your day!

Answer:
a = -5
Step-by-step explanation:
6a + 20 = 2a
6a = 2a - 20
4a = - 20
a = -5
Then it is likely that the amount of mice will decrease and either keep going down because the organism is eating them off too quickly or stay at a medium rate
