Rose bought a new hat when she was on vacation.The following formula describes the total amount Rose paid t = c + cb = total cos
Marianna [84]
 I think the answer is $1,033.50, because the total amount she paid, was the cost of the hat plus the sales tax. So, to find the total sales tax you multiply 975 and 0.06 (6% in decimal form) which is $58.50. Then you add $58.50 to $975, which gives you $1,033.50.

What are the exact solutions of x2 = 5x + 2? (1 point)
bazaltina [42]

Answer:

A. x equals 5 plus or minus the square root of thirty-three all over 2

Step-by-step explanation:

Let's move all the terms to one side:

x^2=5x+2

x^2-5x-2=0

Now, we want to use the quadratic formula, which states that for a quadratic equation of the form ax^2+bx+c=0, the roots can be found with the equation: x=\frac{-b+\sqrt{b^2-4ac} }{2a} or x=\frac{-b-\sqrt{b^2-4ac} }{2a}.

Here, a = 1, b = -5, and c = -2, so plug these in:

x=\frac{-(-5)+\sqrt{(-5)^2-4(1)(-2)} }{2(1)}=x=\frac{5+\sqrt{25+8} }{2}=\frac{5+\sqrt{33} }{2}

OR

x=\frac{-(-5)-\sqrt{(-5)^2-4(1)(-2)} }{2(1)}=x=\frac{5-\sqrt{25+8} }{2}=\frac{5-\sqrt{33} }{2}

Thus, the answer is A.

Hope this helps!
