Show that sin (x + pi) = -sin x.

Lunna [17]

Answer:

The answer in the procedure

Step-by-step explanation:

we know that

$sin(A + B) = sin A cos B + cos A sin B$

In this problem we have

$sin(x + \pi)=sin (x)cos(\pi) + cos(x)sin(\pi)$

Remember that

$sin(\pi) = 0$

$cos(\pi) = -1$

substitute

$sin(x + \pi) = sin(x)(-1) + cos(x)(0)$

$sin(x + \pi) = -sin(x)$

Alex wants to have $2,500 in his bank account after 2 years. If the account earns 5% interest compunded 2 times per year, how mu

natka813 [3]

$A=P(1+ \frac{r}{n})^{nt}$
A=futurer amount
P=present amount
r=rate in decimal
n=number of times compounded per year
t=time in years

A=2500
r=0.05
n=2
t=2

$2500=P(1+ \frac{0.05}{2})^{(2)(2)}$
$2500=P(1+ 0.025)^{4}$
$2500=P(1.025)^{4}$
$2500=P(1.025)^{4}$
divide both sides by [tex} 1.025^{4} [/tex]
2264.88=P
