The rule of law of the square root of constants is taking the nearest divisible number which has a square root of an integer. In this case, 50 is divisible by 25. Hence sqrt of 50 is 5 sqrt 2. The sqrt of a variable applies the multiplication rule. x^6 is raised to 0.5 equal to x^3. Hence the answer is 5 x3 sqrt 2.

Answer:
28
Step-by-step explanation:
p(x)=-2(x-9)^2+100
Let x= 15
p(15)=-2(15-9)^2+100
Parentheses first
= -2 ( 6) ^2 + 100
Then exponents
= -2 * 36 + 100
Then multiply
= -72 + 100
Then add
=28
So because it was $5 off, and she paid 80% of the original price, that would mean it would have been 20% off. That means 20% = $5. Multiply that by 5 to get to 100% and you find that the shirt is $25 originally. Then you can either multiply that 20% = $5 by 4 to get 80%, or just subtract $5 from the full price. That means Selina paid $20 for the shirt.
