Damm [24]

Answer:

$A - B = 135 \degree$

Step-by-step explanation:

Recall the trigonometric identity:

$\tan(A - B)=\frac{\tan A-\tan B}{1+\tan A \tan B}$

We substitute;

tan A=-1/7 and tan B=3/4

$\tan(A - B)=\frac{ - \frac{1}{7} - \frac{3}{4} }{1 - \frac{1}{7} \times \frac{3}{4} }$

$\tan(A - B) = - 1$

This implies that,

$A - B = { \tan}^{ - 1} ( - 1)$

$A - B = { \tan}^{ - 1} ( 1) + 90$

$A - B = 45+ 90$

$A - B = 135 \degree$

Find a10 given the geometric sequence 3, 12, 48, 192, ...

notka56 [123]

Answer:

Step-by-step explanation:

first term = a = 3

common ratio = 2nd term ÷ first term

= 12 ÷ 3

r = 4

$a_{n} = ar^{n-1}\\\\a_{10}=3*4^{9}\\\\\\ = 3 * 262144\\\\= 786432$
