Answer:
Here's what I get.
Step-by-step explanation:
1) Solve the equation for y
y + 2 = ½(x + 2)
y = ½(x + 2) - 2
(2) Create a table containing a few values of x and y
I chose x = -2, 0, and 2.
(3) Plot your points
Draw dots at the coordinates of each point.
(4) Draw the graph
Draw a smooth line through the points.
Extend the lines in both directions to the edges of the plot area.
Your graph should look something like the diagram below.
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
Answer:
-5
Step-by-step explanation:
Geometric sequences have common ratios.
You can see if a sequence is geometric by computing:
.
If you get the same result per consecutive pair, then there is a common ratio and the sequence is geometric.
Let's see:
So if this equations holds (if all 3 fractions equal the same thing), then is geometric and we have also have computed the common ratio.
The first fraction results in -250/50=-5.
The second fraction results in 50/-10=-5.
The third fraction results in -10/2=-5.
All three fractions are equal and so the equation holds so it is geometric and the common ratio is -5.
