Transmutation is the process of changing the substance, tangible or not, from one form to the other. It means the transformation of one element in the periodic table into another by one or a series of nuclear decays or reactions. One type of transmutation is nuclear transmutation. Nuclear transmutation is the conversion of one chemical element or isotope into another though nuclear reactions or nuclear decay. Second type of transmutation is artificial transmutation. Artificial transmutation occur in machinery that uses nough energy to cause changes in the nuclear structure of the elements.

so, he takes mary out on a date he has $13.50 they go out to the movies and he buys two tickets 60% of his money was the cost of

alex41 [277]

2 tickets cost $8.10. 1 ticket is $4.05. Just multiply the money he has by .6 for 2 tickets and then divide the number you get by 2 for the price of 1 ticket. Hope this helps!

Find the first, fourth, and tenth terms of the arithmetic sequence described by the given rule.

steposvetlana [31]

An arithmetic sequence with first term a, and a common distance d si as follows:

m, m+d, m+2d, m+3d, ...

(for example: 3, 8, 13, 18 .... m=3, d=5)

let $\displaystyle{ a_n$ be the n'th term of the arithmeti sequence

m, m+d, m+2d, m+3d, ...

then

$a_1=m\\\\a_2=m+d\\\\a_3=m+2d\\\\a_4=m+3d \\\\ .\\\\.$

so it is clear that the n'th term, si given by :

$a(n)=m+(n-1)d$

compare the rule we found with the given rule A(n)=-3+(n-1)(-2.2)

it is clear that m=-3, and d=-2.2,

so the sequence

m, m+d, m+2d, m+3d, ...

becomes:

-3, -3-2.2, -3-2*2.2, -3-3*2.2, ....

so

-3, -5.2, -7.4, -9.6

the first term is -3, the fourth term is -9.6, the 10th term can be found by plugging in n=10 in the formula:

<span>A(10) = –3 + (10 – 1)(–2.2)=-3+9(-2.2)=-3-19.8=-22.8

remark, we could have use the formula directly and solve for A(1), A(4) and A(10),

but with the explanations we see how we find derive the formula, and makes it easier to derive, even when we don't remember it properly.

Answer:

1st term=-3

2nd term=-9.6

10th term = -22.8</span>
