Find a function f whose graph is a parabola with the given vertex and that passes through the given point.

1 answer:

3 0

A parabola is an approximately U-shaped, mirror-symmetrical plane curve in mathematics. It corresponds to a number of seemingly unrelated mathematical descriptions, all of which can be shown to define the same curves. A parabola can be described using a point and a line.

A parabola equation is what is it?

A parabola's general equation is written as y = a(x - h)2 + k or x = a(y - k)2 + h.

To determine the equation of a parabola, we can utilize the vertex form. Assuming we can read the coordinates (h,k) from the graph, the aim is to utilize the coordinates of its vertex (maximum point, or minimum point), to formulate its equation in the form y=a(xh)2+k, and then to determine the value of the coefficient a.

Represent the relationship between the total cost and the number of items, if total cost t is proportional to the number n of it

kvv77 [185]

Answer:

t = pn

Step-by-step explanation:

We are to find the relationship between total cost and the number of items.

First we would represent the relationship between total cost and number of items with variables

Let the total cost = t

and the number of items = n

Total cost t is proportional to the number n of items:

t ∝ n

t = kn

where k is constant

Since it is purchased at a constant price p, the constant of proportionality would be p. the k would be replaced with p

t = pn

5u − –20u − u − 18u + –11u = 10<br> HURRRY PLEEEEESEEEE I ONLY HAVE 4 minutes left

drek231 [11]

5u - (-20u) - u - 18u + (-11u) = 10
5u + 20u - u - 18u - 11u = 10
-5u = 10
-5(-2) = 10

So, in conclusion, X, is equal to -2.

-BARSIC- [3]

Answer:

Each cookie is $0.67

Step-by-step explanation:

Equation:

1.94 + 12c = 9.98

12c = 8.04

c = 8.04/12

c = 0.67

1 cookie was $ 0.67

What is the equation of the directrix of the parabola given by the equation y2 = -24x?

erma4kov [3.2K]

The equation of the directrix of the parabola given is x = 6, Option D is the correct answer.

<h3>What is Directrix of a Parabola ?</h3>

A parabola is a U shaped curve whose all point are at same distnace from a point called as focus and a line called as Directrix .

The equation of the parabola given is

y² = -24x

When the standard equation of parabola is

(y - k)² = 4p (x - h),

where the focus is (h + p, k) and the directrix is x = h - p.

here h = 0

p = -24/4 = -6

x = 0 - (-6)

x = 6

Therefore Option D is the correct answer.
