That looks very hard, keep trying with the steps so yeah
W-13=15 add 13 on both sides to isolate variable and you get w=13+15, w=28
d = log₂p represents a logarithmic function, The expression log₂(10) tells us when the population reaches 10,000 and the equation 7 = log₂(128) tells us that the population reaches 128,000 in 7 days.
<h3>What is an
exponential function?</h3>
An exponential function is in the form:
y = abˣ
Where a is the initial value of y and b is the multiplication factor.
Let p represent the bacteria population in thousand after d days.
Since each day, the bacteria population grows by a factor of 2, hence:

Hence, d = log₂p represents a logarithmic function
The expression log₂(10) tells us when the population reaches 10,000 and the equation 7 = log₂(128) tells us that the population reaches 128,000 in 7 days.

Answer: D. 8/5
`
Step-by-step explanation:
This is a proportional relationship which means that y/x= k .The y value divided by the x value will give you k which is the slope or in other words the constant variable.
So just divide the y value by the x value to find the k.
(5,8)
The y value is 8
The x value is 5
8/5 = k
k = 8/5
