Write an equation to express the value of h+k

Mathematics
1 answer:
bonufazy [111]3 years ago
3 0

When written in "vertex form":
• (h, k) is the vertex of the parabola, and x = h is the axis of symmetry.

• the h represents a horizontal shift (how far left, or right, the graph has shifted from x = 0).

• the k represents a vertical shift (how far up, or down, the graph has shifted from y = 0).

• notice that the h value is subtracted in this form, and that the k value is added.
             If the equation is y = 2(x - 1)2 + 5, the value of h is 1, and k is 5.
             If the equation is y = 3(x + 4)2 - 6, the value of h is -4, and k is -6.

The circumference of a circle is 12.56 cm. What is the area? Use 3.14 for PI
tankabanditka [31]
Hola!

Circumference of circle is 12.56 cm
Means,

2 × π × r = 12.56

r = 12.56 × 3.14 × 2

r = 1.999 cm

According to Question,

Area of Circle:

π × r²

3.14 × 1.99 × 1.99

12.547 cm² = 12.56 cm² (approximately.)

Hence,
Area of Circle is 12.56 cm²

hope it helps!
