In "Triangle" ABC, AB = x, BC = y, and CA = 2x. A similarity transformation with a scale factor of 0.5 maps "Triangle" ABC to "T

riangle" MNO, such that vertices M, N, and O correspond to A, B, and C, respectively. If OM = 5, what is AB?
A.AB = 2.5
B.AB = 10
C.AB = 5
D.AB = 1.25
E.AB = 2

Answer:

The correct option is <u>C.) AB = 5</u>

Step-by-step explanation:

the diagram of given triangle is shown in figure-1

M, N and O correspond to A , B and C respectively.

and also given that triangle MNO is 0.5 times of triangle ABC

so, MN =(0.5)AB , NO = (0.5)BC and MO =(0.5)AC

then  

      MO =(0.5)AC

       Put OM = 5

        5 =(0.5)AC

   Divide both the sides by 0.5,

                       \frac{5}{0.5}=AC

                   10 = AC

If AB = x and AC = 2x

                  AC = 2x

                   10 = 2x

                  \frac{10}{2}=x

                    5  = x

since  AB = x the AB = 5

 hence, correct option is <u>C.) AB = 5</u>

Mary is inscribing a square in the circle shown, but she is having difficulty remembering the process. Which summary describes t
Ivenika [448]

Answer:

C. Create the perpendicular bisector of FG. Then use the points of intersection of the perpendicular bisector with the circle, along with points F and G, to draw the square.

Step-by-step explanation:

The steps are below:

1. A diameter of the circle is drawn.

2. A perpendicular bisector of the diameter is drawn using the method described in the perpendicular bisector of a segment. This is also a diameter of the circle.

3. The resulting four points on the circle are the vertices of the inscribed square.

ANSWER ASAP PLEASE AND SHOW YOUR WORK!!!!

Answer:

f(-x)= -f(x) so, the given function f(x)= x^3-2x is Odd

Step-by-step explanation:

We need to determine if the function f(x)= x^3-2x is Even, Odd, or Neither.

Determining if a function f(x) is even or not we put x=-x and check

If f(-x)=f(x) the function is even

if f(-x)= -f(x) the function is odd

So, Putting x =-x and determining if the given function f(x)= x^3-2x is Even, Odd, or Neither.

f(x)= x^3-2x\\Put \ x=-x\\f(-x)=(-x)^3-2(-x)\\f(-x)=-x^3+2x\\f(-x)=-(x^3-2x)\\f(-x)=-f(x)

As f(-x)= -f(x) so, the given function f(x)= x^3-2x is Odd
