Answer:

cos210=cos(180+30)=−cos30=−√32 . sin210=sin(180+30)=−sin30=−12 . 3(cos210+isin210) =3(−√32)+3i(−12). −(32)√3−(32)i. My favourite way of seeing that sin30=12 and cos30=√32 is ...

Answer:

b=5

Step-by-step explanation:

We are going to use the basics of algebra to solve this

We need to isolate b by itself to find the value of b.

$8b + 12 = 52$

Subtract 12 from both sides

$8b = 40$

$b = 5$

Help Please! Solve for d. 5+d>5−d Solve for p. 2p+3>2(p−3)

Keith_Richards [23]

Solve for d.
5+d>5−d Subtract 5 from both sides of this inequality:

d>d There is no value for d that satisfies this inequality.
No value can be greater than itself.

Solve for p.
2p+3>2(p−3) Multiply this out: 2p+3>2p-6
 Subtr 3 from both sides: 2p> 2p-9

This is equivalent to 2p+9>2p.
We could subtr. 2p from both sides: 0>-9.

0> -9 is always true. Thus, the given inequality has infinitely many solutions.
