Find the percent of change round to the nearest percent original: 50 new: 70
kykrilka [37]

The percent change is 40%

Step-by-step explanation:

The percent change is given by the formula

Percent\ change=\frac{New\ value-Original\ value}{Original} * 100

Here

New value = 70

Original value = 50

Putting the values in the formula

Percent\ change=\frac{70-50}{50}*100\\=\frac{20}{50}*100\\=0.4*100\\=40\%

The percent change is 40%

Statistical models predict that the price (in dollars) of a 500 GB hard drive will change according to the function p(t) = 600 −
Leni [432]

Let p be a fixed value of price. The expression for t given a value of p is as follows:

p=600-2t^2\\2t^2 = 600-p\\t^2 = \frac{600-p}{2}\\|t| = \sqrt{\frac{600-p}{2}}\\t=\sqrt{\frac{600-p}{2}},\,\,\,\,\,\,t\geq 0,\,\,p\leq 600

What are the coordinates of the vertex of the parabola with the equation y = x2 + 2x – 3?
Sonbull [250]

Answer:

  A.  (-1, -4)

Step-by-step explanation:

The vertex can be found by converting the equation from standard form to vertex form.

<h3>Vertex</h3>

Considering the x-terms, we have ...

  y = (x^2 +2x) -3

where the coefficient of x is 2. Adding (and subtracting) the square of half that, we get ...

  y = (x^2 +2x +(2/2)^2) -3 -(2/2)^2

  y = (x +1)^2 -4

Compare this to the vertex form equation ...

  y = a(x -h)^2 +k

which has vertex (h, k).

We see that h=-1 and k=-4. The vertex is (h, k) = (-1, -4).

On the attached graph, the vertex is the turning point, the minimum.
