Answer:

  (1/4, 5 7/8)

Step-by-step explanation:

The vertex is the extreme point of the graph. Here, it is a minimum.

For this quadratic function, a graphing calculator can tell you exactly what the vertex is. (No approximation is required.)

__

The graphing calculator in the attachment shows the vertex is ...

  (0.25, 5.875) = (1/4, 5 7/8)

A computer costs £927 plus VAT, where VAT is charged 20% find the total cost of the computer
liubo4ka [24]

A computer costs 927 plus VAT where VAT is 20%. We need to find the total cost of the computer.

The total cost = original cost + VAT

Total Cost = 927 + 20% * 927

20% converts to decimal by moving the decimal 2 units up, so it is 0.2

= 927 + 0.2*927

Multiply to find value of tax

= 927 + 185.4

Add to find the total cost

Total cost = 1112.4 euros

Supplementary? Vertical? Complementary? Acute?
liraira [26]

Answer:

A. supplementary

Step-by-step explanation:

Note the angle measurements of BOC. m∠BOC = 90°

Now note that line FC is a straight line, which makes it's measurement = 180°

Subtract 90 from 180: 180 - 90 = 90°

Both are 90°, which, when combined makes a supplementary angle.

What is 1 standard deviation on a
PilotLPTM [1.2K]

Answer:

  D. The distance from the mean to an inflection point

Step-by-step explanation:

We rarely encounter the actual formula for the normal PDF. It is ...

  p(x)=\dfrac{1}{\sqrt{2\pi}}e^{-\dfrac{x^2}{2}}

In fact, the inflection points are at x = ±1, where the curve changes from being concave downward to concave upward.

So, one standard deviation is the distance from the mean to an inflection point.
