Answer:
D: 109 cm
Step-by-step explanation:
The formula of circumference is

Diameter =

Hence, circumference =

rounded of to 109.
Considering the axis of symmetry formula is x = -b / 2a , we can fill in this with the equation given, making it x = -(6) / 2(3) which comes out to -1
So the axis of symmetry for 3x^2 + 6x + 4 is -1
Answer:
0
Step-by-step explanation:
If we solve the inequality for y, we get ...
1/2 > y . . . . divide both sides by 2
That is true only for the value 0 from the given set.
Just put in the x values for example
First one x = 1
y = 2(1) + 5
y= 7

Answer:
B
Step-by-step explanation:
Reflection is a transformation that preserves lengths.
Triangle XYZ, with side lengths XY = 7 in, YZ = 5 in, XZ = 4 in, is reflected across the x-axis to result in △X'Y'Z'.
This means that corresponding sides have the same lengths:
- XY = X'Y' = 7 in;
- XZ = X'Z' = 4 in;
- YZ = Y'Z' = 5 in.
Find the perimeters of both triangles:

Hence, only option B is true.
