On a coordinate plane, any movement up and down is on the y-axis. So if your parallelogram is moving down 2.5 units, then the y-values of each vertice will go down by 2.5:
A(-2, -8), B(-4, -8), C(-3, -4.5), D(-1, -4.5)
Answer:
y>-4+2x/5
Step-by-step explanation:
In the year 2009 there were 3500 birds on an island. If the bird population is declining 2.2% per year it means that in the year 2014 we will have 3500*

= 3131.57 birds.
The best prediction is that in the year 2014 the bird population will be 3132.
Answer:

Step-by-step explanation:
The equation for exponential decay function is given as:

where:
D(t)= difference in temperature t=time
r=rate of change
a =initial value of the temperature
From the given problem:
Initial Temperature,a=50°C
Rate of Decay,r=
Therefore the function for the difference in temperature is given as:


We can convert
to decimal and write the function as:
