phoebe needs to use 3/4 cup to make one batch of cookies how many batches can she make with 12 cups of sugar?

sattari [20]

$\bf \begin{array}{ccll}\stackrel{sugar}{cups}&\stackrel{cookies}{batches}\\\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\\frac{3}{4}&1\\\\12&b\end{array}\implies \cfrac{\quad \frac{3}{4}\quad }{12}=\cfrac{1}{b}\implies \cfrac{\quad \frac{3}{4}\quad }{\frac{12}{1}}=\cfrac{1}{b}\\\\\\\cfrac{3}{4}\cdot \cfrac{1}{12}=\cfrac{1}{b}\implies \cfrac{3}{48}=\cfrac{1}{b}\implies 3b=48\implies b=\cfrac{48}{3}\implies b=16$

the vertex of this parabola is at (3,-2). When the x-vaue is 4, the y-value is 3. What is the coefficient of the squared express

bixtya [17]

<h3>Answer: 5</h3>

=========================================================

Explanation:

Vertex form is

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

We are told the vertex is (3,-2), so we know (h,k) = (3,-2)

y = a(x-h)^2 + k will update to y = a(x-3)^2 - 2

--------

Then we also know that (x,y) = (4,3) is a point on the parabola. Plug those x and y values into the equation and solve for 'a'

y = a(x-3)^2 - 2

3 = a(4-3)^2 - 2

3 = a(1)^2 - 2

3 = a - 2

3+2 = a

5 = a

a = 5

This is the coefficient of the x^2 term since the standard form is y = ax^2+bx+c.

Which statement describes the effect on the parabola f(x)=2x•x-5x+3 when changed to f (x)= 2x•2-5x+1

o-na [289]

Answer:

The parabola is translated down 2 units.

Step-by-step explanation:

You have the parabola f(x) = 2x² – 5x + 3

To change this parabola to f(x) = 2x² - 5x + 1, you must have performed the following calculation:

f(x) = 2x² – 5x + 3 -2= 2x² - 5x + 1 <u><em>Expresion A</em></u>

The algebraic expression of the parabola that results from translating the parabola f (x) = ax² horizontally and vertically is g (x) = a(x - p)² + q, translating in the same way as the function.

If p> 0 and q> 0, the parabola shifts p units to the right and q units up.
If p> 0 and q <0, the parabola shifts p units to the right and q units down.
If p <0 and q> 0, the parabola shifts p units to the left and q units up.
If p <0 and q <0, the parabola shifts p units to the left and q units down.

In the expression A it can be observed then that q = -2 and is less than 0. So the displacement is down 2 units.

This can also be seen graphically, in the attached image, where the red parabola corresponds to the function f(x) = 2x² – 5x + 3 and the blue one to the parabola f(x) = 2x² – 5x + 1.

In conclusion, <u><em>the parabola is translated down 2 units.</em></u>
