Find the vertex of this parabola.<br><br><br><br> y = -2x2 + 4x + 12
STatiana [176]
For this case we have the following equation:
 y = -2x ^ 2 + 4x + 12&#10;
 Deriving we have:
 y = -2x ^ 2 + 4x + 12&#10;&#10;y '= -4x + 4
 We match zero:
 -4x + 4 = 0&#10;
 We clear the value of x:
 4x = 4&#10;&#10;x = 4/4&#10;&#10;x = 1
 Then, we substitute the value of x in the equation of the parabola:
 y = -2 (1) ^ 2 + 4 (1) + 12&#10;&#10;y = -2 + 4 + 12&#10;&#10;y = 14
 Thus, the vertex of the parabola is the ordered pair:
 (x, y) = (1, 14)
 Answer:
 
The vertice is:
 
(x, y) = (1, 14)

1.) What is a qualitative prediction? * and 2.) What is a quantitative prediction? * THERE IS A PIC THAT COME WITH QUESTION PLEA
frozen [14]
I believe a qualitative prediction requires a prediction with out any numerical data to support it while a quantitative predictions require a prediction supported by numerical data.

A real world example of this is in chemistry during a lab.  qualitative data is based off of observation with out numerical data such as a color change.  quantitative data is based off of observation with numerical data such as the mass changes.

(quantitative prediction is decision from data based on percentages, probabilities, and so on while qualitative predictions are based off of given information).
I hope this helps and let me know if you need further explaining.

Find the missing dimension of the prism. Round your answer to the nearest hundredth.
Nitella [24]

Answer:

x = 6.99in

Step-by-step explanation:

Given

l =2in

Volume = 72.66in^3

See attachment for prism

Required

Find x

The prism has a regular hexagon base

The base area is calculated as:

Base\ Area= \frac{3\sqrt 3}{2}l^2

This gives:

Base\ Area= \frac{3\sqrt 3}{2} * 2^2

Base\ Area= \frac{3\sqrt 3}{2} * 4

Base\ Area= 3\sqrt 3 * 2

Base\ Area= 6\sqrt 3

Side x represents the height.

So, we have:

Volume = Base\ Area*x

Make x the subject

x = \frac{Volume }{ Base\ Area}

x = \frac{72.66in^3}{6\sqrt 3 in^2}

x = \frac{72.66}{6\sqrt 3}in

x = \frac{12.11}{\sqrt 3}in

x = 6.99in --- approximated
