a 8
Step-by-step explanation:
You are given two sides and the included angle. Since you don't have any side and the opposite angle, you must use the law of cosines.





Answer: a = 8 cm
Answer:
(x + 3)² + (y -2)² = 4
Explanation:
Circle Formula: (x -h)² + (y -k)² = r²
"r" is radius, "h" is x coordinates of center, "k" is y coordinate of center.
Here given:
Insert values:
(x -(-3))² + (y -2)² = 2²
(x + 3)² + (y -2)² = 4
Answer:
C
Step-by-step explanation:
The answer is going to be miles per quart. So B is wrong.
12 gallons allows you to travel 192 miles
1 gallon permits 192 / 12 = 16 miles / gallon. (Must be a truck of some kind).
1 gallon permits 16 miles of driving.
4 quarts (in 1 gallon) permits 16 miles of driving.
1 quart gives 16/4 = 4 miles / quart.
The answer is C.
==========================
There is a slightly shorter way
12 gallons contains 12 * 4 quarts = 48 quarts.
48 quarts permit 192 miles
1 quart permits 192/48 = 4 miles
4miles / quart.
The answer is still C
