Answer:
( -1, 4 )
Step-by-step explanation:
I'm not sure if I'm right, but a positive function is above the x-axis. Out of all the answer choices, I would have to go with (-1, 4)
I hoped this helped in any way!
9/20
A percentage is the same as showing a number over 100 and if we multiply 20 by 5 we get 100. So if we multiply 9 by 5 we get 45, giving us 45/100 which can be shown as 45%.
As a decimal, well if we say 100% equals 1.0, then 45% equals 0.45
Hello there! :)
First, we. must make sure that variables are on the left side of the equation and numbers are on the other side.
-x=-12-11
-x=-23
x=23
Hope it helps!

Answer:
After 45.7 years
Step-by-step explanation:
∵ r = 1/2% per year
∵ P0 = $40
∵ Pn = $50
∵ Pn = P0 ( 1 + r/100)^n-1
∵ P0 is initial value , Pn is the value after n years , is the rate
∴ 50 = 40 (1 + 0.5/100)^n-1
∴ 50/40 = (1.005)^n-1
∴ 1.25 = (1.005)^n-1 ⇒ insert ln in both sides
∴ ln(1.25) = (n-1)ln(1.005)
∴ n - 1 = ln(1.25)/ln(1.005)
∴ n = ln(1.25)/ln(1.005) + 1 = 45.7 years
