Veseljchak [2.6K]

Answer:

Pairs (2,4), (4,8) and (5,10) makes the equation y=2x true

Step-by-step explanation:

By using the equation y=2x, eval the following points (gathered from the attached picture)

1. (2,4) which leaves us 4=2*2

2. (4,8) which leaves us 8=4*2

3. (5,10) which leaves us 10=5*2

If tan A = 4/5; what does CSC A =?<br> Round to nearest tenth.

ZanzabumX [31]

Answer:

1.6

Step-by-step explanation:

$\tan \: A = \frac{4}{5} \\ \\ \cot \: A = \frac{1}{ \tan \: A } = \frac{1}{ \frac{4}{5} } = \frac{5}{4} \\ \\ csc\: A = \sqrt{1 + {cot}^{2}\: A} \\ = \sqrt{1 + { \bigg( \frac{5}{4} \bigg)}^{2} } \\ = \sqrt{1 + \frac{25}{16} } \\ = \sqrt{\frac{16 + 25}{16} } \\ = \sqrt{\frac{41}{16}} \\ = \frac{ \sqrt{41} }{4} \\ = \frac{6.40312424}{4} \\ = 1.60078106 \\ \therefore \: csc \: A =1.6$
