Mikayla's scooter is worth around $8470 after 4 years.
It was originally worth 13,500 dollars and depreciated by 11% every year.
Answer:
a) 20 units
b) 2 √10 units
c) 2 √17 units
Step-by-step explanation:
The distance formula is;
D = √(y2-y1)^2 + (x2-x1)^2
a) D = √(-7-9)^2 + (-7-5)^2
D = √256 + 144
D = √400
D = 20
b) D = √(10-8)^2 + (9-2)^2
D = √(2)^2 + 6^2
D = √4 + 36)
D = √40
D = 2 √10 units
c) D = √(1 + 7)^2 + (-8+10)^2
D = √(64 + 4)
D = √68
D = 2 √17 units
Rewind the "mind movie" of what happened. She added $74 to her account and then had $192. Back it up by subtracting the $74 from $192.
192 - 74 = 118
Answer: f(-6) =
, f(-4) =
, f(4) =
, f(6) = 
<u>Step-by-step explanation:</u>
(-6, f(-6)) is an x,y coordinate. They are asking what the y-value is when you plug in -6 for x.
f(x) = 
f(-6) = 
= 
= 
f(-4) = 
= 
= 
= 
f(4) = 
= 
= 
= 
f(6) = 
= 
= 
292.5-139.1=153.4
153.4-67.7=85.7
