B) DAB , because 43+47=90 degrees
A quadratic equation has the standard form:
ax^2 + bx + c = 0
in the given equation,
a = 3
b = -10
c = 5
plug these values into the quadratic formula.
(-b +/- sqrt(b^2 - 4ac)) / (2a)
(-(-10) +/- sqrt((-10)^2 - 4(3)(5)) / (2*3)
(10 +/- sqrt(100 - 60)) / (6)
(10 +/- sqrt(40)) /6
c^2 = a^2 + b^2 c^2 = 7^2 + 7^2 = 49 +49 c^2 = 98 c = sqrt 98 c = 9.8 cm c = diagonal of square (9.8 cm) and is less than the diameter of the circle (11 cm), so the square will fit inside the circle without touching the edge of the circle.

Slope = change in y / change in x
= (15 - 9) / (7 - 5)
= 6 / 2
= 3
