zhenek [66]

Answer:

35°

Step-by-step explanation:

From the sketch made, to obtain B we use the cosine angle formula :

We have 2 so des and an included angle

Cos B = (a² + c² - b²) / 2ac

First we obtain the side c

c² = a² + b² - 2ab CosC

c² = 11.2² + 6.7² - 2(11.7 * 6.7) * cos 72

c = 11.13

Using the value of c

Cos B = (a² + c² - b²) / 2ac

CosB = (11.2² + 11.13² - 6.7²) / (2*11.2*11.13)

Cos B = 204.4269 / 249.312

B = Cos^-1(204.4269 / 249.312)

B = 34.9°

Can someone pease help
Hatshy [7]

ANSWER

f(1) =  - 34

f(n) = f(n - 1) + 13

EXPLANATION

The given sequence is;

-34,-21,-8,5,....

The first term of the sequence is

f(1) =  - 34

The common difference is

d = 5 -  - 8

d = 5 + 8 = 13

The recursive definition is given by;

f(n) = f(n - 1) + d

f(n) = f(n - 1) + 13

for n=2,3,4,...
