Answer:
f(x) = 4(2/3)ˣ represents exponential decay.
Hence, option D is the correct function.
Step-by-step explanation:
The function of the form
where and
is called the exponential decay function.
If we replace base 'b' by 1 - r, then we get the decay function of the form
y = abˣ
where 0 < b < 1
- <em>Please note that an exponential function cannot have a base of 0, 1, or a negative value.</em>
Now, if we carefully observe, the function f(x) = 4(2/3)ˣ is the only option correct as
f(x) = 4(2/3)ˣ
here 0 < b < 1 and a > 0
Therefore, f(x) = 4(2/3)ˣ represents exponential decay.
Hence, option D is the correct function.
Answer:
4/1000
Step-by-step explanation:
0,004 -> 004
1 + amnt of the cases (3) = 1000
Answer: The number is -16
Step-by-step explanation: We start by assigning a letter to represent the unknown number. Hence, let the number be y.
One fourth of a number, or in this case, one-fourth of y, can also be written as 1/4 times y. That can now be expressed in its simplest form as
y/4.
Sixteen less than one-fourth of y, can also be re-written as
y/4 - 16.
Therefore if the question says, “sixteen less than one-fourth of a number is equal to -20...” we can now write out the question as follows
(y/4) - 16 = -20
For the left hand side of the equation we can find the LCM as 4, and that can now be written out as
(y - 64)/4 = -20
By cross multiplication we now have
y - 64 = -20 (4)
y - 64 = -80
Add 64 to both sides of the equation
y - 64 + 64 = -80 + 64
y = -16
Therefore the unknown number is -16
All you have to do is subtract.
7 3/8 - 3 10/12
Change it into a common denominator: 24
7 3/8 = 7 9/24
3 10/12 = 3 20/24
7 9/24 - 3 20/24 =
6 33/24 - 3 20/24 = 3 13/24
Answer = 3 13/24 ( 85/24 )
