Answer:
Step 2
Step-by-step explanation:
The quadratic formula is given by 
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

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
Answer:
b. 29°
Step-by-step explanation:
Answer:
128
26 +26 is 52.
Total sum of the angles has to be 180.
180-52=128
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
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)
