Determine the coordinates of the vertex for each quadratic function and whether the parabola has a maximum or minimum. 4. y = x²

GREYUIT [131]

Answer:

minimum, coordinates of vertex: (-3,-11)

explanation:

$\sf y =x^2 +6x-2$

x coordinates on vertex:

solving steps:

$\sf \dfrac{-b}{2a}$

$\sf \dfrac{-6}{2(1)}$

$\sf -3$

Find y-coordinate on vertex:

$\sf y =x^2 +6x-2$

$\sf y =(-3)^2 +6(-3)-2$

$\sf y =-11$

$\mathrm{If}\:a < 0,\:\mathrm{then\:the\:vertex\:is\:a\:maximum\:value}$

$\mathrm{If}\:a > 0,\:\mathrm{then\:the\:vertex\:is\:a\:minimum\:value}$

coordinates: (-3,-11) thus minimum

then the company payed off : 10890 - 4350 = 6540 <== so they paid off
6540.....or 6540/10890 = 60% of the debt

A new physical therapy is being tested in an experimental setting to see if

PolarNik [594]

Answer:

Control Group.

Step-by-step explanation:

A control group, in research, is a group that is not experimented by the researchers in an experiment. A control group is the opposite of an experimental group, on which the independent variable is performed. In other words, an independent variable is held on 'control' in control group.

In the given scenario, the experiment is being performed to test a new physical therapy. To do so, the researchers divided the group in three groups, in which, one group did not receive any treatment; the treatment is held on 'control' in this group.

So, according to the definition provided, the group that did not receive the treatment will be called a control group, thus the correct answer.
