Answer:

Summary:

Standard form allow us to quickly find the y-intercept.

Vertex form allow us to quickly locate the vertex.

And factored form allows us to quickly determine the roots/zeros.

Step-by-step explanation:

The three forms of quadratics are the standard form, vertex form, and the factored form. Each of them reveals a specific part about the quadratic.

Standard Form:

The standard form of a quadratic is:

[tex]ax^2+bx+c[/tex]

There are only two details that can be conveyed by a quadratic in standard form immediately: (1) the leading coefficient a, and (2) the y-intercept.

The leading coefficient a will tell us if the parabola curves upwards or downwards.

And the constant c will give us the y-intercept.

Vertex Form:

The vertex form of a quadratic is:

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

There are also two details that can be conveyed by a quadratic in vertex form:  (1) the vertex, and (2) the leading coefficient.

The leading coefficient is given by a. Again, this tells us the orientation of the parabola.

And the vertex is given by (h, k).

Hence, in my opinion, vertex form is the best form of a quadratic since it immediately reveals the vertex, the most important aspect of a quadratic.

Factored Form:

The factored form of a quadratic is:

[tex]a(x-p)(x-q)[/tex]

Where p and q are the zeros/roots/solutions of the quadratic.

Again, factored form gives us two details about the quadratic: (1) the leading coefficient, and (2) the zeros.

The zeros tells us when the parabola crosses the x-axis, which can assist in graphing.

Summary:

Therefore, each form of a quadratic equation has its own benefits.

Standard form allow us to find the y-intercept.

Vertex form allow us to quickly locate the vertex.

And factored form allows us to quickly determine the roots/zeros.

Hence, depending on the question, each form can be useful in its own way.

Answers:

x = 12

angle A = 30 degrees

===========================================================

Explanation:

Check out the attached image below.

Note the pair of (8x+4) angles which are congruent vertical angles.

Also, notice that 50+130 = 180 since those adjacent angles are supplementary. In other words, they form a straight line.

Now that we know the expressions for each interior angle, we add them up and set the sum equal to 180. Recall that for any triangle, the interior angles always add to 180.

Let's solve for x

(3x-6) + (8x+4) + (50) = 180

11x + 48 = 180 .... combine like terms

11x = 180-48 ..... subtract 48 from both sides

11x = 132

x = 132/11 ..... divide both sides by 11

x = 12

Use this to find the value of angle A

A = 3x-6

A = 3*12-6

A = 36 - 6

A = 30

For the sake of completeness, let's find 8x+4 as well. This part is optional

8x+4 = 8*12+4 = 96+4 = 100

The three interior angles of the triangle are: 30, 100, 50

Note how 30+100+50 = 180 to help confirm the answer.

Answer:

1) El helado costó $135,65.

2) a) Gastó en total $487,5. b) Le dieron $112,5 de vuleto.

Step-by-step explanation:

1) Podemos encontrar el costo del helado como sigue:

[tex] T = J + A + H [/tex]

[tex] H = T - J - A = 250 - 28,85 - 85,50 = 135,65 [/tex]

Por lo tanto, el helado costó $135,65.

2) a) Para saber cuanto dinero gastó debemos sumar todos los precios:

[tex] T = B_{p} + B_{g} + P = 349,50 + 108,25 + 29,75 = 487,5 [/tex]

Entonces, gastó en total $487,5.

b) Si pagó con $600, su vuelto fue:

[tex] V = 600 - T = 600 - 487,5 = 112,5 [/tex]

Le dieron $112,5 de vuleto.

Answer:

Kay sold 6 boxes and Ayan sold 19 boxes

Step-by-step explanation:

Let x be the number of boxes sold by Kay and

Let y be the number of boxes sold by Ayan

Then according to given statements, the equations will be:

[tex]x+y = 25\ \ \ Eqn\ 1\\x = y-13\ \ \ Eqn\ 2[/tex]

Putting x = y-13 in equation 1

[tex]y-13+y = 25\\2y-13=25\\2y=25+13\\2y = 38\\\frac{2y}{2} = \frac{38}{2}\\y = 19[/tex]

Putting y = 19 in equation 2

[tex]x = 19-13 = 6[/tex]

So we get x=6 and y=19

Hence,

Kay sold 6 boxes and Ayan sold 19 boxes

Answer:

B (300, 400)

Step-by-step explanation:

The profit maximization will be when the sum of the products will be greater. The maximum profit will be when x is 300 and y is 400. If we put in the equation :

P = 40x + 55 y

A - When x =  0 , y = 500

P = [40 * 0] + [55 * 500]

P = 27500

B -

When x =  300 , y = 400

P = [40 * 300] + [55 * 400]

P = 34000

C -

When x =  380 , y = 200

P = [40 * 380] + [55 * 200]

P = 26200

D -

When x =  400 , y = 0

P = [40 * 400] + [55 * 400]

P = 16000

C would be the answer

Step-by-step explanation:

Answer:

We are given

Scientist begins with 150 milligrams of a radioactive substance

so,

we can use formula

we can plug Po=150

After 29 hours, 75 mg of the substance remains

so, at t=29 , P=75

we can plug it

now, we can solve for k

now, we can take ln on both sides

now, we can plug it back

and we get

we can plug t=33

we get

Answer:

x = 8

Step-by-step explanation:

Since the triangle is isosceles then the 2 legs are congruent.

Given the perimeter is 66, then sum the 3 sides and equate to 66, that is

x + 4x - 3 + 4x - 3 = 66 , that is

9x - 6 = 66 ( add 6 to both sides )

9x = 72 ( divide both sides by 9 )

x = 8

Answer:

y = 2x

Step-by-step explanation:

Since we are told what to find, we can find the equation of the line that models the statement.

Using the equation of a line

y = MX+c.

m is the slope

c is the intercept

x represents the number of kids in a group (slope)

y represents the total number of caramel chews Gabe gives to that group.

If Gabe gives a group of 3 kids a total of 6 caramel chews and he gives a group of 5 kids 10 caramel chews, we can represent this as coordinate points;

(3,6) and (5,10)

Get the slope

M = 10-6/5-3

M = 4/2

M = 2

Get the intercept by substituting m= 2 any of the points (let's use (3,6)) into the expression y = MX+c to get the value of c;

y = MX+c

6. = 2(3)+c

c = 6-6

c = 0

Substitute m = 2 and c = 0 to get the required equation

y = MX+c

y = 2x+0

Hence the equation that models the statement is y = 2x

Answer:

  tables A, B, E are proportional relationships

Step-by-step explanation:

Finding the rate of change involves finding the ratio of the difference of adjacent y-values to the difference of adjacent x-values. For this many tables and points, I find that to be exceptionally tedious, so I let a spreadsheet do the work.

For the four points, there are three ratios. In the attachment, each ratio is between the point on the same line and the point on the next line. Two conditions are required for the table to be proportional:

The green color identifies tables that are proportional.
