Answer:
The New England colonies had rocky soil, which was not suited to plantation farming, so the New England colonies depended on fishing, lumbering, and subsistence farming.
The <em>effective nuclear charge</em> is the difference between the atomic number an element and the shielding constant. Hence, the atom which experiences the greatest nuclear charge is Sulphur, S.
<u>Calculating the greatest effective nuclear charge</u>, :
- Z = Atomic number ; S = shielding constant
<u>For Magnesium, Mg</u>:
Z = 12
S = 10
<u>For Aluminium, Al</u>:
Z = 13
S = 10
For Sulphur, , S:
Z = 16
S = 10
Therefore, the atom whuch experience the greatest is Sulphur.

the value of P(7), given P(x) = negative4(x minus 15)2 + 2 is 1721.
The problem above can be solved using the ideal of polynomial.
<h3>What is a Polynomial?</h3>
Polynomials are mathematical expressions whereby the highest degree of their unknown is 2 and above.
Given:
- P(x) = negative4(x minus 15)2 + 2
Expand the expression
- P(x) = -4(x²-30x+225)+2
- P(x) = -4x²+120x+900+2
- P(x) = -4x²+120x+902
To find P(7), we subtitute 7 as the value of x in the expression above
- P(7) = -4(7²)+120(7)+909
- P(7) = -28+840+909
- P(7) = 1721
Hence, the value of P(7), given P(x) = negative4(x minus 15)2 + 2 is 1721.
