Answer:
√7i = x
Step-by-step explanation:
x²+y²=9;
y² = 9-x²
y = √(9-x²)
As line is given by y= 4, the solution of the system is:
4 = √(9-x²)
16 = 9-x²
7 = -x²
-7 = x²
√-7 = x
As √-7 doen't exist, you should use i = √-1;
Thus,
<em>√7i = x</em>

Answer:
$140
Step-by-step explanation:
Total Amount of chocolate = 100 Pounds
Amount of chocolate in one box = 1 1/4 Pounds = 5/4 Pounds
Number of boxes = 100/(5/4) = 80 boxes
Cost of one box = $1.75
Total selling price = 80×1.75 = 140
The total selling price for all the boxes of chocolate is $140
Answer:
B. a warm coat, because the winters will be cold
Step-by-step explanation:
Continental climates are notable for extreme weather conditions. When it is hot, it is extremely hot and when it is cold, it is extremely cold. Tropical climates on the other hand are known to always have hot weather conditions.
Since Harry is already used to the tropical climate which largely features hot temperatures, we assume that he already has suitable clothing for such weather conditions. So, in addition to that, Harry would need warm clothing for the cold winters which he would experience in the continental climate. So, Harry would need a warm coat because the winter will be cold.
