Which of the following options is a Pythagorean Identity

alexdok [17]

None of them really, but C is equivalent to the Triognometric Pythagorean Theorem:

$(\sin x + \cos x)^2 = 1 + 2 \sin x \cos x$

$\sin^2 x + 2 \sin x \cos x + \cos ^2 x = 1 + 2 \sin x \cos x$

$\sin^2x + \cos ^2x = 1$

That's the Trigonometric Pythagorean Theorem

Luis wants to buy a skateboard for $79.99. All merchandise is discounted 12%. What is the total cost of the skateboard if Luis h

VikaD [51]

First you need to figure out the cost of the skateboard after the discount but before the sales tax. By doing 100%-12% you figure out how much of the original cost you are paying 88%. Then you multiply 79.99(original cost) and 88%(how much you pay) which gets you 70.39. Then you figure out the sales tax by multiplying 70.39 by 6.75% which gives you 4.75(the sales tax). And the last thing you need to do is add the cost before tax(70.39) and the tax(4.75).
The skateboard costs $75.14
