Laura got a discount of 100 dollars on her purchase of a 5775 bed.What is the percent of decrease?

matrenka [14]

Remember that percent means parts out of 100
x/100

discount is the decrease
so we divide the decrease by the original total and get
100/5775=0.0173
convert to fraction
0.0173/1
make bottom number 100
multiply by 100/100
1.73/100=1.73%
round
2%

Use the half-angle formulas to find the exact value of the trigonometric function sin 15°

VikaD [51]

Answer:

sin 15° = 0.2588

Step-by-step explanation:

The half angle formula is:

$\sin{(\frac{x}{2})} = \pm \sqrt{\frac{1 - \cos{x}}{2}}$

sin 15°

The double of 15º is 30º. First quadrant, so the sine is positive.

$\sin{15} = sqrt{\frac{1 - \cos{30}}{2}}$

Since $\cos{30} = 0.866$

$\sin{15} = sqrt{\frac{1 - \cos{30}}{2}} = \sqrt{\frac{1 - 0.866}{2}} = 0.2588$

sin 15° = 0.2588

The quotient of two expressions is the division of the expressions

The quotient of $\frac{7^{-1}}{7^{-2}}$ is 7

<h3>How to determine the quotient</h3>

The expression is given as:

$\frac{7^{-1}}{7^{-2}}$

Rewrite the above expression by applying the law of indices

$7^{-1 + 2$

Simplify the exponent

$7^{1$

Evaluate the exponent 7 raise to the power of 1

Hence, the quotient of $\frac{7^{-1}}{7^{-2}}$ is 7
