Answer:
1.54 [km²].
Step-by-step explanation:
1) the given scale is for linear functions, the given area of the lake is quadratic function. According to this
2) actual area = given area *50000 *50000;
3) the given area=0.000616 [m²],
the actual area=0.000616*50000*50000=1540000 [m²] or 1.54 [km²].

No. Because -2 has two outputs. To be a function each input have to have one output. I.E
2,3 4,5 6,7 8,9 are functions.
Answer:
b) 22
Step-by-step explanation:
180 = (4x+12) + (3x+14)
180 = 7x + 26
7x = 154
x=22
The overall change is -150 feet. 50 times 5 is 150 feet, and the mountain climber descended. Therefore, the change is -150 feet in elevation.
