What is 4,7,12,19,28 in quadratic form
Naddik [55]
Asked and answered elsewhere.
brainly.com/question/9247314

You obviously don't mind using "technology" (Brainly) to answer these questions. A graphing calculator can do quadratic regression on the sequence and tell you its formula.

If you want to do it by hand, you can write the equation
.. y = ax^2 +bx +c
and substitute three of the given points. Then solve the resulting three linear equations for a, b, and c.
.. 4 = a +b +c
.. 7 = 4a +2b +c
.. 12 = 9a +3b +c

Subtracting the first equation from the other two reduces this to
.. 3 = 3a +b
.. 8 = 8a +2b
The latter can be divided by 2, so reduces to
.. 4 = 4a +b
Subtracting the first of the reduced equations from this, you have
.. 1 = a
so
.. 3 = 3*1 +b
.. 0 = b
and
.. 4 = a + b + c = 1 + 0 + c
.. 3 = c

And your equation is
.. y = x^2 +3 . . . . . . as shown previously

Work out the area of a circle with a radius 6.2cm, take n/pi to be 3.142 and give your answer to 2 decimal places.
s344n2d4d5 [400]

Answer:

Step-by-step explanation:

Area is pi times r squared.  I don't know how to write that on the keyboard.  Take your pi(3.142) times the radius(6.2)squared.  Pemdas tell us to do exponents first, so 6.2 squared is 38.44.  To square a number, just multiply it times itself.  So now, we have pi(3.142) times the squared radius(38.44).  So, 3.142X38.44=

120.778  Second place is seven followed by eight.  Round up.  120.78
