No the graph does not represent a function , it does not pass the vertical line test
Answer 9
The first value behind the decimal point is 0.
When rounding if the value is 0-4 then the value you are rounding to remains the same.
If the value is 5-9 then the value would round up.
However, because it is a 0 it remains a 9.
Divide both sides by 174594
(3600000/174594)=ln(x/1.25)
remmeber
lnx=
and
means
so
(3600000/174594)=ln(x/1.25) means
multily both sides by 1.25

Distance formula : sqrt ((x2 - x1)^2 + (y2 - y1)^2
1.) (-4,0).....x1 = -4 and y1 = 0
(4,6)......x2 = 4 and y2 = 6
now sub into the formula...
d = sqrt ((4 - (-4)^2 + (6 - 0)^2)
d = sqrt ((4 + 4)^2 + (6^2))
d = sqrt (8^2 + 6^2)
d = sqrt (64 + 36)
d = sqrt 100
d = 10 <=====
u would use the exact same formula for the rest of these problems
2.) (5,7),(0,-5)......distance is : 13
3.) (2,-1),(1,-4).....distance is : 3.16
4.) (-7,-2),(0,7).....distance = 11.4
0.24 is read as 24 hundredths (you read the number then add the place of the last digit of the number)
24 hundredths is 24/100, which can be simplified to 6/25 (just keep dividing numerator and denominator by common factor of 2)
