we know that

AB and BC are congruent

That means

AB=BC ----> equation A

we have

AB=12.5\ units

substitute in equation A

BC=12.5\ units

therefore

<u>the answer is the option B</u>

12.5\ units

Since, AB and BC are the same length, the measure of the chord for BC would be 12.5 units

A square is folded into half to form a rectangle. the perimeter of the rectangle is 36cm. calculate the area of a square​
zhannawk [14.2K]

Answer:

Let the measure of each side of the square be " x " cm.

then ,

area of square = x²

After we folded the square into a rectangle ,

length of rectangle = x

breadth of rectangle = x/2

perimeter of rectangle = 36 cm

x +  \frac{x}{2}  + x +  \frac{x}{2}  = 36 \\  \\    \frac{2x + x + 2x + x}{2}  = 36 \\  \\   \frac{6x}{2}  = 36 \\  \\ 6x = 36 \times 2 \\  \\ 6x = 72 \\  \\ 6x =  \cancel{\frac{72}{6} } = 12cm

hence ,

side of square = 12 cm

therefore ,

area of square = 12 × 12 = 144 cm²

hope helpful~

What are the coordinates of the vertex of the graph of the absolute value function h(x) = 3|x + 5| + 2? A) (5,-2) B) (-5,2) C) (
saw5 [17]

Answer:

B) Vertex = (-5, 2)

Step-by-step explanation:

Vertex can be defined as defined as the point where two lines meet and form a particular angle with each other. It can also be described as the point where a line changes its direction

We can find vertex by two methods:

<h3>1) GRAPH</h3>

We can see in the graph attached below that the line changes its direction at point (-5, 2). So the vertex is (-5,2)

<h3>2) FORMULA</h3>

General form of equation of mod function is given by

y = a |x - h| + k

where Vertex = (h, k)

The given equation is

h(x) = 3 |x + 5| + 2

h(x) = 3 |x - (-5)| + 2

where h = -5 and k = 2

So the vertex is:

Vertex = (-5, 2)

PLEASE HELP!
Andrej [43]

Answer:

For the circle with the diameter of 7cm, the <u>area is about 38.48cm</u> and the <u>circumference is about 22cm</u>

For the circle with the diameter of 5cm, the <u>area is about 19.63cm</u> and the <u>circumference is about 15.7cm</u>

Step-by-step explanation:

The formula to find the area of a circle is pi*r^2

The formula to find the circumference is 2*pi*r

r = radius, which can be determined simply by taking the diameter, and dividing it by 2.
