Harry is trying to solve the equation y = 2x2 − x − 6 using the quadratic formula. He has made an error in one of the steps belo
professor190 [17]

Answer:

Step 2

Step-by-step explanation:

The quadratic formula is given by x=-b+-\frac{\sqrt{b^{2}-4ac } }{2a}

Our equation is y = 2x²-x-6

So here our a = 2, b = -1, and c = -6

We can now plug these numbers into our formula

x= -(-1) +-\frac{\sqrt{(-1)^{2}-4(2)(-6) } }{2(2)} = 1 +-\frac{\sqrt{1+24} }{4} = 1+-\frac{\sqrt{25} }{4}

Step 2 is incorrect because it states that "x equals the negative of negative 1 plus or minus the square root of negative one plus forty-eight all over two times 2."

The correct statement would be "x equals the negative of negative 1 plus or minus the square root of positive one plus forty-eight all over two times 2.", because the square of a negative is positive, resulting in a positive one.

Since this step is incorrect, the steps after are also incorrect, but Harry went wrong at Step 2

50 PTS Identify the parent function that can be used to graph the function f(x)=(1/4x)^3
Kobotan [32]

Answer:

f(x) = x^3

Step-by-step explanation:

f(x) = (1/4x )^3

y = f(Cx)  

y = x^3  and C = 1/4

This function is stretched in the x direction

The parent function is x^3

klasskru [66]
The corresponding sides of the 30,60,90° angles are 1,√3, and 2 respectively.

s/6=1/√3

s=6/√3 if we rationalize the denominator...

s=2√3

s≈3.46 units (to nearest hundredth)
