Answer:

[tex]y = (x - 7)^{2} + 7[/tex].

Step-by-step explanation:

Let [tex]a[/tex], [tex]h[/tex], and [tex]k[/tex] be constants, and let [tex]a \ne 0[/tex]. The equation [tex]y = a\, (x - h)^{2} + k[/tex] represents a parabola in a plane with vertex at [tex](h,\, k)[/tex].

For example, for [tex]y = -(x + 7)^{2} + 7 = -(x - (-7))^{2} + 7[/tex], [tex]a = (-1)[/tex], [tex]h = (-7)[/tex], and [tex]k = 7[/tex].

A parabola is entirely above the [tex]x[/tex]-axis only if this parabola opens upwards, with the vertex [tex](h,\, k)[/tex] above the [tex]x\![/tex]-axis.

The parabola opens upwards if and only if the leading coefficient is positive: [tex]a > 0[/tex].

For the vertex [tex](h,\, k)[/tex] to be above the [tex]x[/tex]-axis, the [tex]y[/tex]-coordinate of that point, [tex]k[/tex], must be strictly positive. Thus, [tex]k > 0[/tex].

John's percentage:

36 and 48 have a common factor of 12 so divide both of them by 12.

36/12= 3 and 48/12=4 therefore

so 36/48= 3/4 which is 75% but we don't need to focus on the percent.

Don's no. of shirts:

Answer: 11 adult tickets

Step-by-step explanation:

      First, we will write an equation. Let x be adult tickets and y be children tickets.

   $280 ≥ 18.5x + 12.25y

      Now I will graph it!

-> See attached

    If she bought 6 children's tickets, we can look to the y value of 6 (children's tickets) to find our maximum value of x (adult tickets).

    This means she can buy a maximum of 11 tickets because we will assume she cannot buy part of a ticket.

      She can buy 11 adult tickets.

Answer:

Step-by-step explanation

Since -2+-0.5= -2.5, we need to use a plus sign. Also, since we multiply both by 8.6, that is the answer.

Answer:

D : y = 7x - 20

Step-by-step explanation:

let D be the line that passes through the points (4, 8) and (2, -6)

Then D has an equation of the form D: y = ax + b

Now we need to find a and b in order to be able to write the equation of the line D:

[tex]a = \frac{8-(-6)}{4-2}=\frac{14}{2}=7[/tex]

Since the point (4, 8) lies on the line D then :

8 = 7 × (4) + b

then

8 = 28 + b

then

b = 8 - 28

  = -20

Conclusion:

Since a = 7 and b = -20 then

D : y = 7x - 20

Step-by-step explanation:

the perimeter (P) is the sum of the 3 sides of the triangle.

P = 4x² + 1 + 26x + 6 + x² + 10x ← collect like terms

  = 5x² + 36x + 7

to factor the expression, consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 5 × 7 = 35 and sum = 36

the factors are + 35 and + 1

use these factors to split the x- term

5x² + 35x + 1x + 7 ( factor the first/second and third/fourth terms )

= 5x(x + 7) + 1 (x + 7) ← factor out (x + 7) from each term

= (x + 7)(5x + 1) , then

P = (x + 7)(5x + 1) ← in factored form

Step-by-step explanation:

The formula for the volume of a prism is V=Bh , where B is the base area and h is the height. The base of the prism is a rectangle. 

Subtracting 3x^4+9x^3x^2 from the dividend and bringing down by 13x, the quotient is 3x^2-2x+5, and the term 3x^2 in the quotient is the result of dividing 3x^4 by x²

Polynomial is the combination of variables and constants in a systematic manner with "n" number of power in ascending or descending order.

We have a polynomial:

[tex]=\rm -2x^3-x^2+13x[/tex]

The dividend polynomial:

[tex]\rm = 3x^4+7x^3+2x^2+13x+5[/tex]

If we subtract  the polynomial [tex]\rm 3x^4+9x^3+3x^2[/tex] from the dividend polynomial, we will get:

[tex]\rm = (3x^4+7x^3+2x^2+13x+5)-(3x^4+9x^3+3x^2)[/tex]

[tex]\rm = -2x^3-x^2+13x+5[/tex]

After bringing down 13x, we will get the polynomial:

[tex]=\rm -2x^3-x^2+13x[/tex]

If complete the division of the polynomial, we will get:

[tex]\rm = \frac{(3x^4+7x^3+2x^2+13x+5)}{x^2+3x+1}[/tex]

= [tex]=\rm 3x^2-2x+5[/tex]

Thus, the subtracting 3x^4+9x^3x^2 from the dividend and bringing down by 13x, the quotient is 3x^2-2x+5, and the term 3x^2 in the quotient is the result of dividing 3x^4 by x²

Answer:

113.04

Step-by-step explanation:

Given:V = 324 cu

cmh = 9 cm

Since the formula for the volume of a cylinder is V = AreaBase*heightAreaBase = V/height = 324cu cm/ 9 cmAreaBase = 113.04 square centimetresTherefore, the area of the pillar in square centimeters is 113.04

The base area of the cylindrical pillar would be; 113.04 cm²

The volume of the cylinder is the product of the height, pie, and square of the radius.

v = πr²h

where, r = radius, h = height

Therefore,

v = 324π cm³

h = 9cm

Consider find the radius;

324π = 9πr²

r² = 324π  /9π

r² = 36

r = √36

r = 6 cm

Base area of the pillar = πr²

Base area of the pillar = 36π

Base area of the pillar = 36 × 3.14

Base area of the pillar is 113.04 cm²

Answer:

y-intercept = -5

slope = 2

Step-by-step explanation:

Hello!

The y-intercept is always the y-coordinate when the line touches the y-axis. You can find this by plugging in 0 for x in the equation or choosing the last term in slope-intercept form.

Slope intercept form: y = mx + b

Given this info, we can see that the slope, m, is 2, from our equation of y = 2x - 5, and the y-intercept is -5

The value of x cannot be determined from the information given. The answer choices are all numbers, but they do not follow any obvious pattern. There is no mathematical operation that can be performed on the answer choices to arrive at a single value for x.

If we were given more information about the problem, such as the relationship between the answer choices, then we might be able to determine the value of x. For example, if we were told that the answer choices are all prime numbers, then we could rule out all of the answer choices except for 2 and 3. However, without more information, the value of x cannot be determined.

Here is a more detailed explanation of why the value of x cannot be determined:

Step-by-step explanation:

Let t be the number of years.

We have been given that When Joseph first starts working at a grocery store, his hourly rate is $10.

 For each year he works at the grocery store, his hourly rate increases by $0.50.

So the hourly rates after t years will be 10 plus 0.50t.We can represent this information in an equation as: R(t)=10+0.50t

Therefore, the function  R(t)=10+0.50t represents Joseph's hourly rates after t years.

The sides of the triangle are 45, 60, and 25 ft

Step-by-step explanation:

9 + 12 + 5 equals 26.

Now we need to get the first two sides.

9/26 × 130 = 1170/26 = 45

In order to obtain the other side;

12/26 = 1560/26 = 60

And to obtain the third side:

5/26 × 130 =650/26 = 25

Therefore, the sides of the triangle are 45, 60, and 25 ft
