Simplify and write the trig expression in terms of sin and cos

dsp73

We have:

$cot(-x)cos(-x)+sin(-x)=-\frac{1}{f(x)}$

Then we use trigonometric identities to change the negative sign of the trigonometric functions, so:

$-sin(x)-cot(x)cos(x)=-\frac{1}{f(x)}$

We clear f(x):

$f(x)=\frac{1}{sin(x)+cot(x)cos(x)}=\frac{1}{sin(x)+\frac{cos(x)}{sin(x)}cos(x)}=\frac{1}{sin(x)+\frac{cos^2(x)}{sin(x)}}$

we simply what we can:

$f(x)=\frac{1}{\frac{sin^2(x)+cos^2(x)}{sin(x)}}=sin(x)$

Thus, the correct answer is;

$f(x)=sin(x)$

How much is a 40% discount off of $74.99

pychu [463]

Answer:

$\frac{40}{100} \times \frac{7499}{100}$

$\frac{2}{5} \times \frac{7499}{100}$

$\frac{1}{5} \times \frac{7499}{50}$

$\frac{7499}{250}$

7499/250= 29.996

74.99-29.996= $44.994

Given:

Initial value of new car = $17,500

Depreciation rate = 4.6%

To find:

The value of car after 4 years.

Solution:

The exponential decay model is

$y=a(1-r)^t$

where, a is initial value, r is decreasing rate and t is time in years.

Substitute a=17500, r=0.046 and t=4 in the above equation.

$y=17500(1-0.046)^4$

$y=17500(0.954)^4$

$y=17500(0.8283111)$

$y=14495.44425$

$y\approx 14495.44$

The value of car after 4 years is $14495.44.

Therefore, the correct option is D.
