Find the areas of the trapezoids. PLZ HELP!!!!
barxatty [35]

Answer:

<em>Type 7.5 in the box!</em>

Step-by-step explanation:

Consider the trapezoid formula ( ( base 1 + base 2 ) / 2 ) * height;

Length of Base 1 - 1 unit,\\\\Length of Base 2 - 4 units,\\\\Length of Height - 3 units ( length of x - intercept in shaded region )\\\\Area of Trapezoid = ( Average of Bases ) * Height = ( ( 1 + 4 ) / 2 ) * 3 = ( 5 / 2 ) * 3 = 7.5 square units,\\\\Solution; 7.5 square units

<em>Area = 7.5 square units</em>

Find the value of x for which the graph of y = 3x^2 - 8x + 7 achieves its minimum y-value.​
gulaghasi [49]

Answer:

<h3>The y value achieves its minimum at x = 4/3</h3>

Step-by-step explanation:

Given the graph of y to be 3x² - 8x + 7, to get the value of x for which the graph function achieves its minimum y value, we need to find its turning point first.

At the turning point, dy/dx = 0

Given y = 3x² - 8x + 7

\frac{dy}{dx} = 6x-8\\ at\ turning\ point\ 6x-8 = 0

6x = 8\\x = \frac{8}{6}\\ x =\frac{4}{3}

The y value achieves its minimum at x = 4/3
