Answer:
Alternative A is the correct answer.
Step-by-step explanation:
For a function to have y-axis symmetry then it must be an even function such that; f(-x) = f(x). In alternative A, y = x^2 is an even function since; y(-x) = (-x)^2 = x^2 = y(x). The second function is also even since it has the absolute symbol. Finally, the cosine function is always an even function since cos(-x) = cos(x)
Answer:
Given: In ΔABC ,
To prove that:
[Given]
In ΔADB
The sine angle is defined in the context of a right triangle is the ratio of the length of the side that is opposite that angle to the length of the longest side of the triangle.
[By definition of sine] .....[1]
Multiplication Property of equality states that you multiply both sides of an equation by the same number.
Multiply by c to both sides of an equation [1] we get;
Simplify:
......[2]
Now, In ΔACD
Using definition of sine:
Multiply both sides of an equation by b;
[Multiplication Property of equality]
Simplify:
......[3]
Substitute [3] in [2];
......[4]
Division property of equality states that if you divide both sides of an equation by the same nonzero number the sides remains equal.
[4] ⇒
Therefore, the missing statement in step 6 is;
Answer:
Perimeter = 30.42
Step-by-step explanation:
Using Distance Formula, √((x2-x1)^2 + (y2-y1)^2)
Find the Distance Between NO, OP, and NP
√((-3 - -3)^2 + (3 - 9)^2) - NO = 6
√((-3 - 5)^2 + (9 - -3)^2) - OP = 14.42
√((-3 - 5)^2 + (3 - -3)^2) - NP = 10
Sum All of Them = 10 + 6 + 14.42 = 30.42
Pi is irrational because it cannot be written as a fraction.
