Answer:
You firstly multiply 25,5cm with 20cm equals to 510cm then you divide it with 150 equals 3,4cm
Step-by-step explanation:
(25.5cm × 20cm) ÷ 150cm
≈510cm ÷150cm
≈3,4
This transformation is called a rotation.
Answer:
40 units per sec
Step-by-step explanation:
The average rate of change in this case is the change in y over the first three seconds (which is 220 - 100, or 120) divided by the elapsed time (which is 3 seconds).
120
Thus, we have ------------ = 40 units per sec

Answer:
The formula for the moose population is
Step-by-step explanation:
In 1992—that is, 2 years after 1990 or at 
—the population 
is 3570, and in 1999 (
) population is 3640; so we have
Now the formula that will model the moose population will be of the form:
The slope 
is
therefore we have
Now we know that at 
, so we put these values in and solve for 
With this value of 
, we finally have the formula for the moose population:
