Answer:
C) 5√3
Step-by-step explanation:
To find the length of sides CB, use the tan of 30 degrees.
tan 30 = 5/x Simplify
0.577 = 5/x Divide both sides by 0.577
x = 8.66 or 5√3

The answer to the question, <u>What is true about the graph of the parabola described by the quadratic equation</u> is that the parabola crosses the x-axis at x = ±16.
Since the quadratic equation has roots x = ±16, it implies that its factors are x - 16 and x + 16.
So, the quadratic equation is y = (x - 16)(x + 16) = x² - 16²
Also, we know that the roots of a quadratic equation are the points where the value of the quadratic equation equals zero. At this value, the quadratic equations crosses the x-axis at the roots of the quadratic equation.
Since the roots of our quadratic equation are x = ±16, it implies that the parabola crosses the x-axis at x = ±16.
So, the answer to the question, <u>What is true about the graph of the parabola described by the quadratic equation</u> is that the parabola crosses the x-axis at x = ±16.

Answer:
(1) Conjugate = -i8
(2) Conjugate = -i3+9
(3) Conjugate = i2+1
(4) Conjugate = -3-iy
Step-by-step explanation:
From the question,
Conjugate of a surd is formed by changing the sign between a rational number and a surd in an expression.
The conjugate of a surd is obtained by changing the sign of the surd in the expression.
Given
(1) i3+i5 = i8
Conjugate is -i8
(2) i3+9
Conjugate is -i3+9
(3) -i2+1
Conjugate is i2+1
(4) -3+iy
Conjugate is -3-iy
