(x2 subtracted by x1 divided by 2, y2 subtracted by y1 divided by 2) is the midpoint formula.  
(2-3/2, 5-6/2)= (-1/2, -1/2) which is the answer/

Find the vertex of the parabola formed by the following quadratic function: y = 3x^2 – 6x + 2
storchak [24]
Vertex form is y=a(x-h)^2+k, so we can rearrange to that form...

y=3x^2-6x+2  subtract 2 from both sides

y-2=3x^2-6x  divide both sides by 3

(y-2)/3=x^2-2x, halve the linear coefficient, square it, add it to both sides...in this case:  (-2/2)^2=1 so

(y-2)/3+1=x^2-2x+1  now the right side is a perfect square

(y-2+3)/3=(x-1)^2

(y+1)/3=(x-1)^2  multiply both sides by 3

y+1=3(x-1)^2  subtract 1 from both sides

y=3(x-1)^2-1  so the vertex is:

(1, -1)

...

Now if you'd like you can commit to memory the vertex point for any parabola so you don't have to do the calculations like what we did above.  The vertex of any quadratic (parabola), ax^2+bx+c is:

x= -b/(2a),   y= (4ac-b^2)/(4a)

Then you will always be able to do a quick calculation of the vertex :)

Answer:

  a) Pluto, Mercury, Mars, Venus, Earth, Neptune, Uranus, Saturn, Jupiter

  b) 62

Step-by-step explanation:

When all the numbers are in scientific notation, as these are, the numbers with the smallest exponent are smaller. If numbers have the same exponent, the number with the smaller mantissa is smaller.

a) least-to-greatest diameter, the order is ...

  Pluto, Mercury, Mars, Venus, Earth, Neptune, Uranus, Saturn, Jupiter

__

b) The ratio of diameters of Jupiter and Pluto is ...

  (1.43×10^8)/(2.3×10^6) = 6.2×10^1 = 62

Jupiter's diameter is about 62 times that of Pluto.

_____

If the probability of rain is 31%. What is the probability of it not raining?
-Dominant- [34]

Answer:

69%

Step-by-step explanation:

Since we only have two options, rain or not rain, they have to add to 100%

100 -31 = 69

So not raining is 69%
