Answer:

-2, 1, 6  and the 10th is 97

Step-by-step explanation:

to find the terms, in a row, replace n with 1

nth = 1^2 -3   -2 is the answer  (1^2) is 1 -3 = -2

then replace the n with 2, 3, 4 etc till you have your sequence

nth = 2^2 -3  1 is the answer (2^2) is 4 -3 = 1

nth = 3^2 -3  6 is the answer (3^2) is 9-3 = 6

nth = 4^2 -3  13 is the answer (4^2) is 16-3 = 13

nth = 5^2 -3  22 is the answer (5^2) is 25-3 = 22

etc to 10

nth = 10^2 -3 97 is the answer (10^2) is 100 - 3 = 97

sequence is -2, 1, 6, 13, 22, . . . . 97

Step-by-step explanation:

Tn = n² - 3

Now

the first three terms

t1 = 1² - 3 = 1 - 3= -2

t2 = 2² - 3= 4 - 3 = 1

t3 = 3² - 3 = 9 - 3 = 6

----------------

The first three terms are -2 , 1 , 6

and

tenth term

t10= 10² - 3= 100-3 = 97

Hope it will help you :))

Write a quadratic function with zeroes 6 and 7
RoseWind [281]

Answer:

f(x) = x² - 13x + 42

Step-by-step explanation:

given zeros are x = 6 and x = 7 then the corresponding factors are

(x - 6) and (x - 7)

the quadratic function is then the product of the factors , that is

f(x) = (x - 6)(x - 7) ← expand using FOIL

     = x² - 13x + 42

help 112. if k is a positive integer, then for every value of k, the sum of the k smallest distinct odd positive integers is equ
Ksenya-84 [330]
Hello,

\sum_{i=0}^{k-1}\ (2*i+1)=2*\sum_{i=0}^{k-1}\ i +\sum_{i=0}^{k-1}\ 1\\

= \dfrac{k*(k-1)}{2} +k=k^2-k+k=k^2

In details:

s= 1             +3            +5+7+9+....    +2(k-2)+1      +2(k-1)+1
s= 2(k-1)+1  +2(k-2)+1 +....  +9+7+5  +3                 +1
2s=(2k-2+2) +(2k-4+4)+...........................................+(2k-2+2)
   =2k+2k+2k+....+2k (there is k terms)

2s=2k*k
2s=2k²
s=k²
