Write an equation for the nth term of the arithmetic sequence. Then find a 30

AnnZ [28]

Answer:

The nth term is given by: $a_n = -9 + 3(n-1)$

The 30th term is 78.

Step-by-step explanation:

Arithmetic sequence:

The nth term of an arithmetic sequence is given by:

$a_n = a_1 + (n-1)d$

In which $a_1$ is the first term and d is the common difference between terms.

-9, -6, - 3,0

This means that $a_1 = -9, r = -6 - (-9) = -6 + 9 = 3$ . So

$a_n = -9 + 3(n-1)$

30th term:

$a_30 = -9 + 3(30-1) = -9 + 87 = 78$

The 30th term is 78.

PLEASE HELP ASAP I have no idea how to solve this pls pls pls

xz_007 [3.2K]

Answer:

Step-by-step explanation:

you have to use trigonometric functions

cos 30 = adj. /hyp.

cos 30 = 12 / y

y = 12/cos 30 ≅13.86

tan 30 = opp./adj

tan30 = x / 12

x = 12 tan30 ≅6.93

Three consecutive odd integers are such that the square of the third integer is 33 less than the sum of the squares of the first

Rzqust [24]

If $x$ is the first integer, then

$(x+4)^2=x^2+(x+2)^2-33\iff x^2-4x-45=(x+5)(x-9)=0$

The other possibility is then $x=9$ , so the other two integers would be $x+2=11$ and $x+4=13$ .
