y = 3x^2- 6x + 3
y= -x^2 - 4x + 7
y = -2x^2 + 9x – 11

Answers

Answer:

1. 1 real solution

2. 2 real solutions

3. Two complex solutions

Step-by-step explanation:

y = 3x^2- 6x + 3

This has 1 real solutions.

y= -x^2 - 4x + 7

This has 2 real solutions.

y = -2x^2 + 9x – 11

This has 2 complex solutions.

The number of unique solutions each equation has is required.

[tex]y=3x^2-6x+3[/tex] has one real solution.

[tex]y=-x^2-4x+7[/tex] has two real solutions.

[tex]y=-2x^2+9x-11[/tex] has two complex solutions.

The number of solutions is determined by the value of the discriminant.

Let us find the determinant of each equation

[tex]y=3x^2-6x+3[/tex]

[tex]D=b^2-4ac\\\Rightarrow D=6^2-4\times 3\times 3\\\Rightarrow D=36-36\\\Rightarrow D=0[/tex]

The equation has one real solution.

[tex]y=-x^2-4x+7[/tex]

[tex]D=(-4)^2-4\times (-1)\times 7\\\Rightarrow D=16+28\\\Rightarrow D=44\\\Rightarrow D>0[/tex]

The equation has two real solutions.

[tex]y=-2x^2+9x-11[/tex]

[tex]D=9^2-4\times (-2)\times (-11)\\\Rightarrow D=81-88=-7\\\Rightarrow D<0[/tex]

The equation has two complex solutions.

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

An independent variable is a variable that does not depends on other variable while a dependent variable is a variable that depends on other variable.

Given that:

1 inch = 50 miles

Hence:

4.8 inches = 4.8 inch * 50 miles per inch = 240 miles

The distance between the two cities Dallas and Houston is 240 miles

Step-by-step explanation:

There is nothing to indicate the graph is not of a polynomial function. Its zeros are the x=intercepts: -2, 3, 5. There are 3 of them, so that is the least degree the polynomial might have.

Find u + v if u = (-4,7, 2) and v = (4,1, -3)

Answers

Answer:   (0, 8, -1)

To get this answer, you add up the corresponding coordinates.

The x coordinates add to -4+4 = 0

The y coordinates add to 7+1 = 8

The z coordinates add to 2+(-3) = -1

Another way to express this is to consider

u = (a,b,c)

v = (d,e,f)

which add to u+v = (a+d,b+e,c+f)

The point A has coordinates (-1, 6) and the point B has coordinates (7, 2).

i Find the equation of the perpendicular bisector of AB, giving your answer in the form y = mx + c.

ii A point C on the perpendicular bisector has coordinates (p, q). The distance OC is 2 units, where O is

the origin. Write down two equations involving p and q and hence find the coordinates of the possible

positions of C.

Answers

Answer:

a) y = 2x -2

b) Equation: q = 2p - 2  ----(1)

p² + q² = 4   ----(2)

The coordinates of C may be (0, -2) or (6/5, 8/5)

Step-by-step explanation:

a) Step 1: Find the coordinates of midpoint, P of AB

x-co-ordinate of P = (x₁ + x₂)/2 = (-1 + 7)/2 = 3

y- co-ordinate of P = (y₁ + y₂)/2 = (6 + 2)/2 = 4

Step 2: Determine the gradient, m₂ of perpendicular bisector of AB

For perpendicular lines, m₁ * m₂ = -1 where m₁ is slope of AB

m₁ = (2 - 6)/(7 - -1) = -4/8 = -1/2

-1/2 * m₂ = -1

m₂ = 2

Step 3: Deriving the equation of the perpendicular bisector in the form y = mx + c

y - y₁ = m(x - x₁); substituting the values of the midpoints of the line

y - 4 = 2(x - 3)

y - 4 = 2x - 6

y = 2x -2

b) Step 1: Derive the values of the p and using the formula of distance between two points:

y = 2x - 2

therefore q = 2p - 2  ----(1)

OC = √(x₂ -x₁)² + (y₂ - y₁)²

2 = √(p - 0)² + ( q - 0)²

2 = √p² + q²

squaring both sides

p² + q² = 4   ----(2)

Substituting (1) in (2)

p² + (2p - 2)² = 4

p² + 4p² - 8p + 4 = 4

5p² - 8p = 0

p(5p - 8) = 0

Therefore p = 0 or 5p - 8 = 0

p = 0 or p = 8/5

Substituting p = 0 in (1)

q = -2

substituting p = 8/5 in (1)

q = 2(8/5) - 2

q = 16/5 - 2

q = 6/5

Hence the coordinates of C may be (0, -2) or (6/5, 8/5)
