Equation of the Quadratic Function

The vertex form of the quadratic function has the following equation:

[tex]y=a(x-h)^2+k[/tex]

Where (h, k) is the vertex of the parabola that results when plotting the function, and a is a coefficient different from zero.

The graph provided in the question has two clear points:

The vertex, located at (2,-3)

The y-intercept, located at (0,-7)

Substituting the coordinates of the vertex, the equation of the function is:

[tex]y=a(x-2)^2-3[/tex]

The value of a will be determined by using the other point:

[tex]-7=a(0-2)^2-3[/tex]

Operating:

[tex]-7=a(4)-3[/tex]

[tex]4a=-4\Rightarrow a=-4/4[/tex]

Solving:

a=-1

The equation of the graph is:

[tex]y=-(x-2)^2-3[/tex]

Answer:

(-2,5)

Step-by-step explanation:

use formula: m= ([tex]\frac{x^{1}+x^{2} }{2} , \frac{y^{1}+y^{2} }{2}[/tex])

midpoint(m) equals (4,0) and C is (10,-5)

C represents [tex](x^{1} ,y^{1})[/tex] and other endpoint D represents [tex](x^{2}, y^{2} )[/tex] so:

(4,0) = [tex](\frac{10+x^{2} }{2} , \frac{-5+y^{2} }{2} )[/tex]                  

4 = [tex]\frac{10+x^{2} }{2}[/tex]

[tex]4*2 = (\frac{10+x^{2} }{2} )2[/tex]      Get rid of 2 by multiplying both sides by 2

8 = [tex]10 + x^{2}[/tex]               Subtract both sides by 10

[tex]x^{2} = -2[/tex]                x coordinate of D = -2

To find y coordinate of D:

0 = [tex]\frac{-5+y^{2} }{2}[/tex]                    Get rid of 2 by multiply both sides by 2

0 = [tex]-5 + y^{2}[/tex]                    Add both sides by 5

[tex]y^{2} = 5[/tex]                          y coordinate of D = 5

So if x-coordinate of D= -2 and y-coordinate of D=5, the coordinates for D is (-2,5)

Answer:

x = -3

Step-by-step explanation:

6x - 3 = -18 + x

Subtract x from each side

6x-x - 3 = -18 + x-x

5x -3 = -18

Add 3 to each side

5x-3+3 = -18+3

5x = -15

Divide each side by 5

5x/5 = -15/5

x = -3

Step-by-step explanation:

a D&C show that m is the midpoint

The required figures that show the mid-points are (c) and (d).

A midpoint is a point on the line whose distance from both ends of the line is equal.

Here,
Figures are shown where in figure (A) only point M is shown which does not describe itself. In figure (B) M is located so far from B and there is no point on the other side of M. In figure (C) and (D) Point M is located between two certain points with equal measures.

Answer:

[tex](x^2-4y)(x^4+4x^2y+16y^2)[/tex]

Step-by-step explanation:

Factoring

We need to recall the following polynomial identity:

[tex](a^3-b^3)(a-b)(a^2+ab+b^2)[/tex]

The given expression is:

[tex]x^6- 64y^3[/tex]

To factor the above expression, we need to find a and b, knowing a^3 and b^3. a is the cubic root of a^3, and b is the cubic root of b^3:

[tex]a=\sqrt[3]{x^6}=x^2[/tex]

[tex]b=\sqrt[3]{64y^3}=4y[/tex]

Now we apply the identity:

[tex]x^6– 64y^3=(x^2-4y)[(x^2)^2+(x^2)*(4y)+(4y)^2][/tex]

Operating:

[tex]x^6– 64y^3=(x^2-4y)[x^4+4x^2y+16y^2][/tex]

The remaining factors cannot be factored in anymore. Thus the completely factored form is:

[tex]\boxed{(x^2-4y)(x^4+4x^2y+16y^2)}[/tex]

Answer:

I'm pretty sure the answer is: 6.7 x 10^-3, 6.7%, 6/9, 0.67.

Step-by-step explanation:

Convert everything into decimal form.

6.7 x 10^-3 = 0.0067

6.7% = 0.067

6/9 = 0.66... (repeating decimal)

0.67 = 0.67 (already a decimal)

Once you have converted your numbers into decimals then you can compare them from least - greatest.

6=72

Step-by-step explanation:

if 1 had the number 108 2 would be 72 because both have to equal 180 also say 3 is right under 1 also on the same line it would be also 72 and 4 also on the same line would be 72 .

5 on a different line would be 108 and 6 on the same line as number 5 would be 72 also 7 would be 108 and 8 would be 82

8 would be 72 not 82

Answer:

Each boy recieved $25.25 each

Step-by-step explanation:

First, you add up all the money the 3 boys spent.

15+15+15=45

Then you add the sum of the equation to the amount all the boys had afterward.

45+30.75=75.75

Finally, you divide that product to 3 boys.

75.75/3=25.25

Therfore the answer is $25.25 each.

Hi, I am from India......

Happy to help you..

Answer:

89

Step-by-step explanation:

Given that,

During a promotional weekend, a state fair gives a free admission to every 179th person that enters the fair.

No of people attending the fair on Saturday is 8,633 amd No of people attending the fair on Sunday is 7,400.

We need to find the no of people that received a free admission over the two days.

Dividing 8,633 by 179 gives 48 as quotient and 41 as remainder. It means on Saturday 48 people entered for free.

Dividing 7,400 by 179 gives 41 as quotient and 61 as remainder. It means on Sunday 41 people entered for free.

Total no of people,

T = 48 + 41

T = 89

Hence, there are 89 people for free entries.

Answer:

The initial amount of investment was $7,822

Step-by-step explanation:

The formula for compound interest, including principal sum is:

[tex]A=P(1+\frac{r}{n})^{nt}[/tex], where

Let us use this rule to solve the question

∵ Sam invests a sum of money in a retirement account with a fixed

   annual interest rate of 7% compounded quarterly

∴ r = 7% = [tex]\frac{7}{100}[/tex] = 0.07

∴ n = 4 ⇒ compounded quarterly

∵ After 13 years, the balance reaches $19,280.02

∴ A = 19,280.02

∴ t = 13

Substitute these values in the rule above to find P

∵ [tex]19,280.02=P(1+\frac{0.07}{4})^{4(13)}[/tex]

∴ [tex]19,280.02=P(1.0175)^{52}[/tex]

→ Divide both sides by [tex](1.0175)^{52}[/tex]

∴ 7,821.99888 = P

→ Round it to the nearest dollar

∴ 7,822 = P

∴ P = $7,822

∴ The initial amount of investment was $7,822.

Answer:

x is approximately 69.39 degrees.

Step-by-step explanation:

To find x in this triangle, we can use the sin rule:

[tex]\frac{a}{sin(A)} =\frac{b}{sin(B)}[/tex]

The corresponding angle for each length is the one that lies directly opposite it. E.g. if 3.5 was our length 'a', then 55 degrees would be our angle A.

So let's take 3.5 and 55degrees as our length and Angle A, and 4 and x degrees as our length and angle B as we are trying to solve for x.

This would give us the following equation:

[tex]\frac{3.5}{sin(55)} =\frac{4}{sin(x)} \\[/tex]

Since we are solving for an angle, it will be easier to rearrange the equation if we have it as the numerator, so we can flip the fractions to make it easier. It will still be equal as we are looking for the ratio.

[tex]\frac{sin(55)}{3.5} =\frac{sin(x)}{4} \\[/tex]

From here let's isolate the sin(x) by multiplying by 4 and solving the values we have so far:

[tex]\frac{4 sin(55)}{3.5} =sin(x)\\\frac{3.2766}{3.5} =sin(x)\\0.936=sin(x)[/tex]

Now the final step is to use inverse sin to cancel the sin so we just have x:

[tex]sin^{-1} 0.936=x\\x=69.39[/tex]

x is approximately 69.39 degrees.

Hope this helped!
