Answer:

k is the vertical shift

Step-by-step explanation:

y=a(x-h)^2+k

This gives the parabola in vertex form

(h,k) is the vertex where h is the x coordinate and k is the y coordinate

k is the vertical shift

the area of asquare field is 2.25 hectares.find its perimeter in metres if hectare is qual to 10000square metres

Sergio [31]

Answer:

Perimeter of the square field is 600 meters.

Step-by-step explanation:

Given:

Area of a square field = 2.25 hectares

1 hectare = 10000 m²

∴2.25 hectares = $2.25\times10000 = 22500$ m²

Now, let each side length of the square field be $a$ meters.

∴ Area = $a^{2}$

⇒ $22500 = a^{2}$

⇒ $a=\sqrt{22500}=150$ m

Now, perimeter of a square is given as, $P = 4a$ .

Here, $a=150$ m.

∴ $P=4\times150=600$ m

Hence, the perimeter of the square field is 600 meters.

How many real solutions does the system of equations have? y = x2 + x − 2 y = -x + 1

Delvig [45]

The number of the solutions of the equations are 2 that are (1, 0) and (-3, 4).

<h3>What are the solutions of the equations?</h3>

The equations are given below.

y = x² + x − 2 ...1

y = – x + 1 ...2

From equations 1 and 2, we have

x² + x − 2 = – x + 1

x² + 2x − 3 = 0

Then the factor of the equation will be

x² + 3x – x − 3 = 0

(x + 3)(x – 1) = 0

x = 1, –3

Then the value of y will be

At x = 1, we have

y = -1 + 1

y = 0

At x = -3, we have

y = -(-3) + 1

y = 4

Then the number of the solutions of the equations are 2 that are (1, 0) and (-3, 4).

The graph is given below.

More about the solutions of the equations link is given below.
