Answer:
No. The two ratios do NOT form a proportion.
Step-by-step explanation:
Cross multiply.
13/6 : 2/1
13(1) : 6(2)
13 ≠ 12
The lengths of the segments can be calculated using:
d = √[(y₂-y₁)² + (x₂-x₁)]²
First, we calculate the length of AB using this formula:
L(AB) = 10
Then, we calculate the length of A'B':
L(A'B') = 3
Therefore, the scale factor is: L(A'B') / L(AB) = 3/10
Answer:
Area = 77.1
Step-by-step explanation:
The are of a right triangle is

our base and height are 6 for both triangles, so we shall find the area of one of the triangles...

multiply this by 2

Now find the area of the whole circle

our radius is 6, therefore:

Finally, subtract the area of the two triangles from the total are of the circle. The difference left over is our answer

<h3>
Answer: B.) it is a one-to-one function</h3>
Explanation:
It's a function because it passes the vertical line test. It's also one-to-one because it passes the horizontal line test.
The vertical line test is where we try to draw a single line through more than one point on the blue curve. Such a task isn't possible in this case, and we consider the curve passing the vertical line test. The horizontal line test is nearly identical, but we're dealing with horizontal lines of course.
Answer:
z = 60
Step-by-step explanation:
100+20+z=180
120+z=180
z=60
