Find the 59th term of the arithmetic sequence <br> 29,37,45,...

liberstina [14]

Answer:

13,456

Step-by-step explanation:

Tn= a+(n-1)d

a is the first term, n is the given number and d is the common difference. d is given by subtracting the first term from the second term or the second from the third. Therefore the the 59th term of the sequence 29, 37, 45 is,

Tn= 29+(59-1)8

=29(58)8

=13,456

12. $\frac{r-3}{-4-(-8)} = -5$
$\frac{r-3}{4} = -5$
r - 3 = 4(-5)
r - 3 = -20
r = -20 + 3
r = -17

13. $\frac{r-2}{-2-5} = \frac{5}{6}$
$\frac{r-2}{-7} = \frac{5}{6}$
6(r - 2) = -7(5)
6r - 12 = -35
6r = -35 + 12
6r = - 23
r = $\frac{-23}{6}$

Write a quadratic equation in the form ax^2+bx+c=0 with roots of -4 and 5

Stolb23 [73]

Step-by-step explanation:

- 4 & 5 are roots

Therefore, (x + 4) & (x - 5) are factors.

Required quadratic equation is given as:

$(x + 4) (x - 5) \\ = x(x - 5) + 4(x - 5) \\ = {x }^{2} - 5x + 4x - 20 \\ = {x}^{2} - x - 20 \\$
