the original price of a jacket is $68. The sale price is 30% off the original price. what is the amount off the original price?

Semmy [17]

Answer: The original price of the jacket is given in the question and it is $68.

The percent of discount given on the original price is 30%.

Then

The amount of discount given = (68 * 30/100) dollar

= 20.4 dollar

The discount amount is $20.4

Now after the deduction of the sale percentage, the selling price of the jacket can be easily deduced.

Then

Selling price of the jacket = (68 - 20.4) dollars

= 47.6 dollars

Question 16 (Essay Worth 7 points)<br><br> Verify the identity.<br><br> tan (x + π/2) = -cot x

Rus_ich [418]

Step-by-step explanation:

We know that tan=sin/cos, so tan(x+π/2)=

$\frac{sin(x+pi/2)}{cos(x+pi/2)}$

Then, we know that sin(u+v)=sin(u)cos(v)+cos(u)sin(v),

so our equation is then

$\frac{sin(x)cos(\pi/2)+cos(x)sin(\pi/2)}{cos(x+\pi/2)} = \frac{cos(x)}{cos(x+\pi/2) }$

Then, cos(u+v)=cos(u)cos(v)-sin(u)sin(v), so our expression is then

$\frac{cos(x)}{cos(x)cos(\pi/2)-sin(x)sin(\pi/2)} = \frac{cos(x)}{-sin(x)} = -cot(x)$
