Given:

The graph of a quadratic function passes through the points (5,31) (3,11) (0,11).

To find:

The equation of the quadratic function.

Solution:

A quadratic function is defined as:

[tex]y=ax^2+bx+c[/tex]            ...(i)

It is passes through the point (0,11). So, substitute [tex]x=0,y=11[/tex] in (i).

[tex]11=a(0)^2+b(0)+c[/tex]

[tex]11=c[/tex]

Putting [tex]c=11[/tex] in (i), we get

[tex]y=ax^2+bx+11[/tex]               ...(ii)

The quadratic function passes through the point (5,31). So, substitute [tex]x=5,y=31[/tex] in (ii).

[tex]31=a(5)^2+b(5)+11[/tex]

[tex]31-11=a(25)+5b[/tex]

[tex]20=25a+5b[/tex]

Divide both sides by 5.

[tex]4=5a+b[/tex]                  ...(iii)

The quadratic function passes through the point (3,11). So, substitute [tex]x=3,y=11[/tex] in (ii).

[tex]11=a(3)^2+b(3)+11[/tex]

[tex]11-11=a(9)+3b[/tex]

[tex]0=9a+3b[/tex]

Divide both sides by 3.

[tex]0=3a+b[/tex]                 ...(iv)

Subtracting (iv) from (iii), we get

[tex]4-0=5a+b-3a-b[/tex]

[tex]4=2a[/tex]

[tex]\dfrac{4}{2}=a[/tex]

[tex]2=a[/tex]

Putting [tex]a=2[/tex] in (iv), we get

[tex]0=3(2)+b[/tex]

[tex]0=6+b[/tex]

[tex]-6=b[/tex]

Putting [tex]a=2,b=-6[/tex] in (ii), we get

[tex]y=(2)x^2+(-6)x+11[/tex]

[tex]y=2x^2-6x+11[/tex]

Therefore, the required quadratic equation is [tex]y=2x^2-6x+11[/tex].

Expression: x² - 6x + 9

Factored form: (x - 3)²

Using the concept of factorization.

The breaking or breakdown of an entity (such as an integer, a matrix, or even a polynomial) into such a combination of some other unit, or factors, whose multiplication yields the original number, matrix, etc., is known as factorization or factoring in mathematics.

Similarly to this, factoring is a very useful technique in algebra that is utilized at all levels. Additionally, to, of course, simplify complex expressions, it offers a standard way for solving quadratic equations. Graphing functions also makes advantage of it.

Factor the expression, put each factor equal to 0, and then solve each equation to solve a quadratic equation by factoring. To do this, rearrange all terms on one side of the equation such the other side equals 0.

Given that,

x² - 6x

Now, to find the value of c = (b/2)²

divide the coefficient of x by 2.

So, divide 6 by 2 we get: ( -1.3)²

Next, multiply -1 by 3: (-3)²

Now, raise -3 to the power of 2, we get: 9

So, the expression becomes: x² - 6x + 9

Factorized form: (x - 3) (x -3)

or we can write (x - 3)²

The value of y is 130°

The angles occupy the same relative position at each intersection where a straight line crosses two others. If the two lines are parallel, the corresponding angles are equal.

Given here:

Horizontal and parallel lines b and c are cut by transversal a. At the intersection of lines b and a, the bottom right angle is 50 degrees. At the intersection of lines c and a, the top left angle is y degrees.

Thus the angle adjacent to the 50-degree angle will be 130

but this angle corresponds to the angle y thus y=130 as corresponding angles are equal when a transversal intersects two parallel lines

Hence, The value of y is 130°

Answer:

-3w2-11w-3

Step-by-step explanation:

take w2 and w as variables. you can substitute it as w2=y and w=X then expand brackets

2y-8x-8-5y-3x+5

note that the signed changed at the second part because it was expanded with the minus sign which is basically like -1, so it changes the signs

then you collect like terms:

2y-5y-8x-3x-8+5= -3y-11x-3

now put substitute back w2=y and w=X

-3w2-11w-3

if it won't be a problem solving with w2 and w, then you skip the substitution part and solve the same

Answer:

The area of a square is equal to the side length of the square squared. If the side length of the small square is "s" and the side length of the big square is "b", then we can write the following two equations to represent the area of the two squares:

Area of small square = s^2

Area of big square = b^2

Since the area of the big square is 30 units more than the area of the small square, we can write the equation:

b^2 = s^2 + 30

To find the radius of the circle, we need to find the side length of the small square. To do this, we can rearrange the equation above to solve for s:

s^2 = b^2 - 30

s = sqrt(b^2 - 30)

Now we just need to find the value of "b", which is the side length of the big square. To do this, we can use the fact that the big square is inscribed in the circle, so the side length of the big square is equal to the diameter of the circle. Let's call the diameter of the circle "d". Then we can substitute "d" for "b" in the equation above:

s = sqrt(d^2 - 30)

To find the radius of the circle, we just need to divide the diameter of the circle by 2, so the radius is equal to "d" divided by 2. Therefore, the radius of the circle is:

r = d/2 = sqrt(d^2 - 30)/2

So to find the radius of the circle, we just need to know the diameter of the circle. Can you provide the diameter of the circle in the question?:

The radius of the circle is: r = d/2 = sqrt(d^2 - 30)/2

The area of a circle is π multiplied by the square of the radius. The area of a circle, (A) when the radius 'r' is given is πr2. π is approximately  3.142

Here, we have,

The area of a square is equal to the side length of the square squared. If the side length of the small square is "s" and the side length of the big square is "b", then we can write the following two equations to represent the area of the two squares:

Area of big square = b^2

Since the area of the big square is 30 units more than the area of the small square, we can write the equation:

To find the radius of the circle, we need to find the side length of the small square. To do this, we can rearrange the equation above to solve for s:

Step-by-step explanation:

Solution is below

The height of the rock ledge will be 20.35 meters.

The height of the tree will be 58.75 meters

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

The angle of elevation to the top of a tree is 22°.

And, The angle of depression to the base of the tree is 12°.

Now,

Let the height of the rock ledge = x

So, By figure, we get;

⇒ tan 12° = x / 96

⇒ x = 96 × tan 12°

⇒ x = 20.35 meters

And, Let total height of the tree = x + y

                                                = 20.35 + y

Hence, By figure, we get;

⇒ tan 22° = y / 96

⇒ y = 96 × tan 22°

⇒ y = 96 × 0.40

⇒ y = 38.4 meter

Thus, The height of tree = 38.4 meters + 20.35 meters

                                      = 58.75 meters

To find:-

Answer:-

Part A :-

Here we can see that the distance between the rock ledge and the base of the tree is 96m . Also the angle of elevation to the top of the tree from the rock is 22° .

Firstly, we can see that,

[tex]\implies \angle CAD =\angle EDA = 12^o\\[/tex]

This is so because they are alternate interior angles .

Now , in ∆ADE ,

[tex]\implies \tan\theta =\dfrac{p}{b}=\dfrac{AE}{ED}\\[/tex]

[tex]\implies \tan 12^o =\dfrac{AE}{96m} \\[/tex]

[tex]\implies AE = 96\tan12^o m \\[/tex]

[tex]\implies AE = 96 (0.21)m \\[/tex]

[tex]\implies AE = 20.16 \ m \\[/tex]

Hence the height of the rock ledge is 20.16 m.

_______________________________________

Part B :-

Now in ∆ACB , we have;

[tex]\implies \tan\theta =\dfrac{BC}{AC} \\[/tex]

[tex]\implies \tan 22^o =\dfrac{BC}{96m} \\[/tex]

[tex]\implies BC = 96\tan 22^o \ m \\[/tex]

[tex]\implies BC = 96(0.4) m \\[/tex]

[tex]\implies BC = 38.4 \ m \\[/tex]

Now the total height of the tree will be = BC + AE

[tex]\implies h_{tree}= BC + AE \\[/tex]

[tex]\implies h_{tree}=38.4\ m + 20.16 \ m =\boxed{58.56\ m} \\[/tex]

Hence the height of the tree is 58.56m.

and we are done!
