F(x) = 3x² + 6x - 1

The graph is a parabola open upward (a= 3>0) with a minimum.

Calculate the vertex:

x = -b/2a → x = -6/(2.3) = -1. Then the axis of symmetry is x = - 1
Now to calculate the minimum, plugin the value of x:

y = 3x² + 6x - 1

y = 3(-1)² + 6(-1) -1

y= 3 - 6 -1 and y = - 4,

Ten the vertex (minimum) is at (-1,- 4)

If an English teacher marks 220 essays in 28 hours 36 minutes, how long on average does it take to mark one essay?
Xelga [282]

First, let us break down 28 hours 36 minutes into minutes.

Number of minutes taken to grade 220 essays = (28 x 60) + 36 = 1680 + 36 = 1716 minutes

Now, we can find the average time taken to grade an essay by dividing the time taken to grade 220 essays by 220.

Average amount of time taken to grade an essay = \frac{1716}{220} = 7.8 minutes, or 7 minutes and 48 seconds
