What is the 97th term of the arithmetic sequence -16,2,20

MAXImum [283]

Answer:

1712

Step-by-step explanation:

Given arithmetic sequence is: -16,2,20

Here, a = - 16, d = 2 - (-16) = 2+ 16 = 18

n = 97, $a_{97}=?$

$\because a_n = a + (n-1)d\\\\\therefore a_{97}= - 16 + (97-1)\times 18\\\\\therefore a_{97}= - 16 + 96\times 18\\\\\therefore a_{97}= - 16 + 1728\\\\\therefore a_{97}=1,712\\\\$

Find the distance from point B to point C.

MAVERICK [17]

Answer:

11.2 = BC

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

tan theta = opposite side/ adjacent side

tan 66 = BC/ 5

Multiply each side by 5

5 tan 66 = BC

11.23018387 = BC

Rounding to the nearest tenth

11.2 = BC
