Answer:
(x, y) --> (x + 4, y - 3)
Step-by-step explanation:
The x value concerns left and right, while the y value concerns up and down. Adding to x makes it move right, and adding to y makes it move up.
The correct answer is C) (5×10⁴)(1×10²)
Explanation:
The number of trees can be calculated by the formula:
trees = density × area
Consider that the problem says that the researcher makes an approximation, and the answers have numbers written in scientific notation.
The density is 86 trees/km²,
which can be rounded to 100 trees/km²
and written as <span>1×10².
Therefore, density = </span>1×10² trees/km²
The area of a square can be calculated by the formula:
A = s²
= 220²
= 48400 km²
which can be roundend to 50000
and written as <span>5×10⁴
Therefore, area = </span>5×10⁴ km²
Now, we can substitute in the original formula:
trees = (1×10²)(5×10⁴)
522 dollars X 0.79 euro = 412.38 dollars
