Given the quadratic equation
answer the following questions

"a" value =
vertex =
axis of symmetry: x =
minimum or maximum (spelling counts):
standard form = x^2 - x +

image attached to better understand answering.

Part 1) "a" value is

Part 2) The vertex is the point

Part 3) The equation of the axis of symmetry is

Part 4) The vertex is a minimum

Part 5) The quadratic equation in standard form is

Step-by-step explanation:

we know that

The equation of a vertical parabola into vertex form is equal to

where

(h,k) is the vertex of the parabola

if a > 0 then the parabola open upward (vertex is a minimum)

if a < 0 then the parabola open downward (vertex is a maximum)

The equation of the axis of symmetry of a vertical parabola is equal to the x-coordinate of the vertex

so

In this problem we have

-----> this is the equation in vertex form of a vertical parabola

The value of

so

a>0 then the parabola open upward (vertex is a minimum)

The vertex is the point

so

The equation of the axis of symmetry is

The equation of a vertical parabola in standard form is equal to

Convert vertex form in standard form

see the attached figure to better understand the problem

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.

if the pizza is divided equally into 2 equal halves then you would get

πr^2/2

where r is the radius of the pizza.
