Answer: B -4

Step-by-step explanation:

Value of coefficient of the squared term in the parabola's equation = -4

Correct option is B.

A parabola is a U-shaped plane curve where any point is at an equal distance from a fixed point (known as the focus) and from a fixed straight line which is known as the directrix.

Given,

Vertex of parabola (h,k) = (3, 5)

y = 6 for x = -1

Parabola opens horizontally left side

Vertex-form equation of parabola

x = a(y - k)² + h

-1 = a(6 - 5)² + 3

-1 = a(1) 3

a = -4

Hence, -4 is value of coefficient of the squared term in the parabola's equation.

Answer:

t > 3

Step-by-step explanation:

3(2t - 6) > -2(3t - 9)

Distribute

6t - 18 > -6t + 18

+6t          +6t

12t - 18 > 18

     +18     +18

12t > 36

divide both sides by 12

t > 3

Answer:

Use the Pythagorean theorem

Step-by-step explanation:

The pythagorean theorem is [tex]a^{2} +b^{2} =c^{2}[/tex] where a is a height, b is a height, and c is the hypotenuse, which is the longest side of a triangle. For example, if the triangle has two side with lengths of three and four we would put them into the equation to get:

[tex]3^{2} +4^{2} =c^{2}[/tex]

Simplify the equation to get:

[tex]9+16=c^2[/tex]

Add 16 and 9 to get 25 and take the square root of both sides:

[tex]\sqrt{25} =c[/tex]

The sqrt of 25 is 5. Therefore, the length of the hypotenuse, or c, is 5.

Answer:

Plug your values into the equation A=1/2bh and do the math. First multiply the base (b) by 1/2, then divide the area (A) by the product. The resulting value will be the height of your triangle.

Answer:

AB = 51

BC = 50

AC = 42

PQ = 42

QR = 42

PR = 59

Step-by-step explanation:

Perimeter of ∆ ABC = Perimeter of ∆ PQR

3x + 9 + 3x + 8 + 3x = 3x + 3x + 4x + 3

9x + 17 = 10x + 3

17 - 3 = 10x - 9x

14 = x

.: x = 14

AB = 3x +9 = 3×14+9 = 42+9 = 51

BC = 3x +8 = 3×14+8 = 42+8 = 50

AC = 3x = 3×14 = 42

PQ = 3x = 3×14 = 42

QR = 3x = 3×14 = 42

PR = 4x +3 = 4×14+3 = 56+3 = 59

Correct answer: y>-32x-2

The required equation of inequality is y >  - 3/2 x + 2.

We have given a graph of inequality for finding their equation.

What is inequality?

Inequality is a statement of an order relationship for greater than, greater than or equal to, less than, or less than or equal to, between two numbers or algebraic expressions.

From graph we can see that the line is passing through the points (0,-2) and (-4,4).

Since we know that the slope of a graph,

[tex]m = (y_2 - y_1)/(x_2 - x_1 )[/tex]

    =[tex](4 - (-2))/(-4 - 0)[/tex]

⇒[tex]m = (-3)/( 2)[/tex]

Also we know the equation of line passing through the point (x_(1,)  y_1) having slope be,

[tex]y - y_1 = m (x - x_1)[/tex]

Therefore, the equation of line passing through (0, -2) and having slope -3/2 be,

⇒ y - (-2) = - 3/2 x

⇒ y =  - 3/2 x + 2

Since the graph is shaded left side to the line so, this equation can be written as

y >  - 3/2 x + 2

Thus, this is the required equation of inequality.

Answer:

38.3%

Step-by-step explanation:

We have two equations to find the answer.

1. Discount = OG Price * Discount by 100%

2. Final Price = OG Price - Discount

So fill in the first equation :

Discount = 28.99 * 38.3/100

Discount = 28.99 * 0.38

Saved = $11.10

Now for the second equation :

Final Price = 28.99 - 11.10317

Final Price = $17.89

Therefore the discount is 38.3%

Answer: 40%

Step-by-step explanation:

Number of guests that yesterday called for room service = 170

Number of guests that did not call for room service = 255

Total number of guests = 170 + 255 = 425.

The percentage that call for room service = Those that call for room service / Total guest × 100

= 170/425 × 100

= 0.4 × 100

= 40%
