Answer:
1/6 square miles
Step-by-step explanation:
lw=a
1*1/6=1/6
Answer:
x = 1/2
y = 4
Step-by-step explanation:
4x - y = -2 --------------------(I)
2x + 3y = 13 --------------------(II)
Multiply equation (I) by 3 and then add
(I)*3 12x - 3y = -6
(II) <u> 2x + 3y = 13 </u> {Now add and so y will be eliminated}
14x = 7
x = 7/14
x = 1/2
Plugin x = 1/2 in equation (I)
2 - y = -2
-y = -2 - 2
-y = -4
y = 4
Formula for the Distance between 2 points is √(x₂-x₁)²+(y₂-y₁)²
So the given points are (0,5) 0 is x₁ and 5 is y1
in the 2nd given points (-5,0) -5 is x₂ and 0 is y₂
Now we know what order the points go in so we place them into the formula which you have the following: √(-5-0)²+(0-5)²
Next we work what is in the parentheses first
√(-5)²+(-5)² now we work with exponents √25+25 next we add what's inside the square root symbol √50 the square root of 50 on the calculator gives an answer of 7.07107
Considering the relation {(elephant, 25), (reindeer, 32), (greyhound, 39), (elk, 45)}, we have that:
- The domain is: {elephant, reindeer, greyhound, elk}.
- The range is: {25, 32, 39, 45}.
<h3>What are the domain and the range of a function?</h3>
- The domain of a function is the set that contains all the values of the input.
- The range of a function is the set that contains all the values of the output.
In this problem, the relation is given as follows:
Hence, the relation is {(elephant, 25), (reindeer, 32), (greyhound, 39), (elk, 45)}, and the domain and range are given as follows:
- The domain is: {elephant, reindeer, greyhound, elk}.
- The range is: {25, 32, 39, 45}.

Answer:
A, C, D are true
Step-by-step explanation:
The Law of Cosines tells you that D is true. The equation of D is a rearrangement of the usual presentation of the Law of Cosines.
The given relationship between the squares of the side lengths tells you that C is true. (The relation would be "equals" if the triangle were a right triangle.)
D being true, together with the given condition, tells you that 2ab·cos(θ) must be less than zero. Since the side lengths are positive, the cosine must be less than zero, making statement A true. (When A is true, B cannot be true.)
