Hello!
The variable "n" represents an exponent.
An exponent is used to multiply a number (b) by itself "n" times. For example, if the expression were to read (b²) it would represent the following:
b × b
The same could be said for (b³):
b × b × b
Even (
):
b × b × b × b × b × b × b × b × b × b
I hope this helps!
I think the expression that you need is, 4-(2x). Hope it helps!
Answer:
Step-by-step explanation:
The area of a rectangle can be calculated with this formula:
Where "l" is the length and "w" is the width.
You can identify from the figure that the length and the width of this rectangle are:
Then, you need to substitute this lenght and this width into :
Now, apply Distributive property:
Finally, you need to add the like terms. Then, you get:
If the problem is supposed to read (4^33*8^37)/(4^15*8^21), then...
(4^33*8^37)/(4^15*8^21) = (4^33/4^15)*(8^37/8^21)
(4^33*8^37)/(4^15*8^21) = 4^(33-15)*8^(37-21)
(4^33*8^37)/(4^15*8^21) = 4^18*8^16
Answer: Choice A) 4^18*8^16
Answer:
Tacoma's population in 2014 will be 587,439 people
Step-by-step explanation:
we know that
The equation of a exponential growth function is given by the formula
where
y is Tacoma's population in thousand
x is the number of years since 2000
r is the rate of change
a is the initial value
we have
substitute
what will Tacoma's population be in 2014?
Find the value of x
substitute the value of x
therefore
Tacoma's population in 2014 will be 587,439 people
