Answer:

$274.12

Step-by-step explanation:

The microwave is 15% off from its original price of 299.99. This means that the microwave is only 85% of its price from its original price. To find its discounted price, we do 0.85 (85%) *299.99= 254.99. Then, with the tax added, we do 1.075 * 254.99 (1.075 is the price percentage with the tax) to get 274.12

What is the value of sinθ, given that cosθ=−2/5 and sinθ>0? Simplify radicals and rationalize the denominator, if necessary

Vadim26 [7]

$\cos\theta=-\dfrac25$
$\sin\theta=\pm\sqrt{1-\cos^2\theta}=\pm\dfrac{\sqrt{21}}5$

Take the positive root, since it's given that $\sin\theta>0$ .

$\sin\theta=\dfrac{\sqrt{21}}5$
