Answer: 5 years
Step-by-step explanation:
A= P(1-r)^t
A= Depreciation value
P = Initial amount
r= rate = 7/100= 0.07
t= time
t= (Ln(A/P))/Ln(1-r)
= (Ln(25949.18/37300))/Ln(1-0.07)
t= 4.999 approximately 5 years
Answer: 1.018
Step-by-step explanation:
The pH level of a substance indicates the concentration of hydrogen ions (
) in a solution and is calculated by:

In this case the hydrogen ion concentration is
, where
. Hence:

This means this new substance is acid
Answer:
x-intercept = 4
y-intercept = -1
As ordered pairs they would be ( 4, 0) and ( 0, -1)
Step-by-step explanation:
The line goes through 4 on the x line and goes through -1 on the y line.
As an ordered pair you just put the numbers in their x and y spots being ( x, y )
With 4 being on the X and -1 being on the Y it would make them ( 4, 0) and
( 0, -1).
Answer:
43.96 inches
Step-by-step explanation:
(refer to attached)
circumference = 2πr, where r = 7 inches and π=3.14
circumference = 2 x 3.14 x 7
= 43.96 inches
Answer:
B.
Step-by-step explanation:
y = x
Whatever y is, x must be equal (same) as it.
