Find the possible value or values of y in the quadratic equation 4 – 4y – y 2 = 0. A. y = –3, y = –1 B. y = 2 C. y = –2 + 2√ 2,
xz_007 [3.2K]
  4 - 4y - y² = 0
-y² - 4y + 4 = 0
y = -(-4) ± √((-4)² - 4(4)(-1))
                    2(-1)
y = 4 ± √(16 + 16)
               -2
y = 4 ± √(32)
          -2
y = 4 ± 4√(2)
         -2
y = 4 + 4√(2)    or    y = 4 - 4√(2)
          -2                            -2
y = -2 - 2√(2)    or    y = -2 + 2√(2)

The answer is C.

A circle has a circumference of 6. It has an arc of length
stiv31 [10]

Answer:

The circumference formula for a circle is C=πd where C is the circumference, d is the diameter of the circle and π is a constant. If you plug in 6 for C and solve the equation for d like:

6= πd and then divide both sides of the equation by π you get that d = 1.90

To find the central angle of an arc you would use the equation S = rθ where S is the length of the arc, r is the radius of the circle, and θ is the measure of the angle which in this case is unknown. So with S = 1 and r = d/2 = 1.90/2 = 0.9549 you would have an equation that looks like this:

1 = 0.9549θ.

If you divide both sides of the equation by 0.9549 you get θ = 1.047197 radians.

The question asked for the angle measure in degrees so you would need to convert the angle measure to degrees by multiplying the degree measurement by 180/π
