Mathematics
1 answer:
Elena L [17]2 years ago
5 0

Answer:

(a) 7 + 3( n - 1 )

(b) 1006

Step-by-step explanation:

ARITHMETIC SEQUENCE.

The number of term of an Arithmetic progression has the formular :

nth term = a + ( n - 1 ) d

a = 7

d = 10 - 7 = 3

nth term = 7 + ( n - 1 ) 3

= 7 + 3n - 3

= 7 + 3( n - 1 )

Therefore,

the nth term of the sequence

= 7 + 3( n - 1 )

(b) For the 1000th term

= 7 + 3 ( 1000-1 )

= 7 + ( 999 )

7 + 999 = 1006

Therefore,

the 1000th term = 1006

Can someone pls help? ab to fail geometry. any help is nice.
Mamont248 [21]
By the law of cosines, the angle C satisfies

8.77^2=2^2+9^2-2\times2\times9\times\cos C

which reduces to

\cos C=0.2246\implies C=\arccos(0.2246)\approx1.34422\text{ rad}

which converts to approximately 77 degrees (this can be done my multiplying by 180 and dividing by pi).
