Answer:
Pierre is right
Step-by-step explanation:
The correct formula for Exponential growth rate is given as:
y = a( 1 + r) ^t
Where
y = Amount after time t
a = Initial amount
r = Growth rate
t = time
From the question
a = 300
r = 2% = 0.02
Hence, our exponential growth rate =
y = 300( 1 + 0.02)^t
y = 300( 1.02)^t
Therefore, Pierre is right
Answer: v^2 -4v-21
Step-by-step explanation:
Since the midpoint lies on the axis, both ends are therefore equidistant from the axis and are mirrors of each other so..
Q = (4,9)
For this case we have the following equation:
We must clear the value of the variable "x" as a function of r, s and t:
If we multiply by "r" on both sides of the equation we have:
If we subtract "t" on both sides of the equation we have:
If we divide by "2" on both sides of the equation we have:
Thus, the value of the variable "x" is:
Answer:
Answer:
Unlike terms
Step-by-step explanation:
If it was 4y and 5y it would be like. Adding the x though makes them unlike terms, you cannot combine them
