Part A: Describe the solution(s) to 9x² - 36x + 36 = 0 by just determining the radicand. Show your work. (10 points) Part B: Des

Alik [6]

The solution to the equations are:

9x² - 36x + 36 = 0 has two equal real solutions
x² - x + 4 = 0 has no real solutions
The factored expression of 4x² + 23 – 35 is 4(x² -3)

<h3>Part A: Describe the solution</h3>

The equation is given as:

9x² - 36x + 36 = 0

The above equation is a quadratic equation which can be represented as:

ax² + bx + c = 0

The discriminant (d) is calculated as:

d = b² - 4ac

So, we have:

d = (-36)² - 4 * 9 * 36

d = 0

A discriminant of 0 means that the equation has two equal real solutions

Hence, 9x² - 36x + 36 = 0 has two equal real solutions

<h3>Part B: Describe the solution</h3>

The equation is given as:

x² - x + 4 = 0

The above equation can be represented as:

ax² + bx + c = 0

The discriminant (d) is calculated as:

d = b² - 4ac

So, we have:

d = (-1)² - 4 * 1 * 4

d = -15

A discriminant of -15 means that the equation has no real solutions

Hence, x² - x + 4 = 0 has no real solutions

<h3>Part C: The solution to the expression</h3>

We have:

4x² + 23 – 35

Evaluate the difference

4x² -12

Factor out 4

4(x² -3)

Hence, the factored expression of 4x² + 23 – 35 is 4(x² -3)

What is the approximate area of the shaded region? Circumscribed square with side length 8 meters. The four regions between the

myrzilka [38]

Answer:

13.76 square meters

Step-by-step explanation:

The side of square is 8 meters.

So, the diameter of circle = 8 meters.

⇒ Radius = (diameter of circle) ÷ 2 = 8 ÷ 2 = 4 meters

Shaded region = Area of square - Area of circle

= (Side × Side) - π × (radius)²

= 8 × 8 - π × 4 × 4 {∵ π = 3.14 or 22÷7}

= 64 - 50.24

= 13.76 square meter

Answer:

Q1. $(2x-3)^{2}+3(x-4)=5+y\\$

$4x^{2} -12x+9+3x-12-5-y=0$

$4x^{2} -9x-8-y=0$

$4x^{2} -9x-8=y$

∴ $y = 4x^{2} -9x-8$

∴ From the quadratic equation above, a = 4, b = -9, and c = -8.

Q2. $(x-5)^{2} -x^{2} =y$

$x^{2} -10x+25-x^{2} =y$

$-10x+25=y$

∴ $y = -10x + 25$

∴ The equation above is not a quadratic equation as it does not follow the format of ax² + bx + c.

Q3. $2x(4x^{2} -4x+1)=y+x(8x)+4(2x)$

$8x^{3} -8x^{2} +2x-8x^{2} -8x=y$

∴ $y=8x^{3} -16x^{2} -6x$

∴ The equation above is not a quadratic equation as it does not follow the format of y = ax² + bx + c.
