Answer:
789 Siberian tigers
Step-by-step explanation:
2030 = 40 years after 1990, so...
215 * e^(.0325*40) =
215 * e^1.3 =
788.89878405, which is approx. 789
The perimeter of a square is four times the side, since you have to sum all sides, and they're all the same length:
This is direct variation, because we have
and if the ratio between two variables is constant (in this case, 4), then the two variables are in direct variation.
The perimeter of a square is directly proportional to its side length, therefore it's an example of direct variation.
Yes, the perimeter (P) of a square with side length (n) is an example of direct variation. In this case, P is directly proportional to n. To understand this, think of a square. A square has four equal sides. Thus, its perimeter (P) is n times 4, or P = 4n. If n is increased, the perimeter also increases proportionally, which supports that it's a direct variation relationship. A change in one quantity leads to a proportional change in the other one.

Step-by-step explanation: In this equation, it's important to understand that the number 5 is the coefficient on the variable M. This just means that -5 "times" M equals -40. So, whenever you see a number next to a variable, it means multiplication.
If we were to solve, we would just divide both sides of the equation by 5. On the left the 5's cancel and on the right, -40 divided by 5 is -8.
