HELP!

1 answer:

7 0

Well, 7% of 450 is 31.5. The error can go either way (too much or too little) so 450 - 31.5 = 418.5. We also do 450 + 31.5 = 481.5. The statement would be

Book mass = >418.5 and <481.5.

(This could be wrong, I haven't done this much before.)

A student buys a guitar that is on sale for 15% off the regular price of $200. He also must pay an 8% sales tax. What is his tot

EastWind [94]

Answer:

option c

Step-by-step explanation:

a guitar 15% off means that the cost is now 85%

$100percent---200dollars\\85percent---x\:dollars\\\\x=\frac{200*85}{100}\\\\x=2*85\\\\x=170$

now the 8% of 170 is

$100\:percent---170\:dollars\\\\8\:percent---x\:dollars$

$x=\frac{8*170}{100}\\\\x=\frac{8*17}{10}\\\\x=13.6$

so the total cost is

170+13.6

183.6

Rewrite 2tan3x in terms of tanx

blsea [12.9K]

$2\tan3x=2\tan(2x+x)=\dfrac{2\tan2x+2\tan x}{1-\tan2x\tan x}$

Use the same identity to expand $\tan2x$ .

$\tan2x=\tan(x+x)=\dfrac{\tan x+\tan x}{1-\tan x\tan x}=\dfrac{2\tan x}{1-\tan^2x}$

$\implies2\tan3x=\dfrac{2\dfrac{2\tan x}{1-\tan^2x}+2\tan x}{1-\dfrac{2\tan x}{1-\tan^2x}\tan x}$
$2\tan3x=\dfrac{2\tan x\left(\dfrac2{1-\tan^2x}+1\right)}{1-\dfrac{2\tan^2x}{1-\tan^2x}}$
$2\tan3x=\dfrac{2\tan x\left(2+1-\tan^2x\right)}{1-\tan^2x-2\tan^2x}$
$2\tan3x=\dfrac{2\tan x(3-\tan^2x)}{1-3\tan^2x}$
