Answer:

Up down and side to side on the graph

Step-by-step explanation:

If a is 1, since it is positive the parabola moves up. If a is -1, since it is negative the parabola moves down. (not sure about side to side because I can't back that one up but I'm 100% sure about up and down)

When a is between 0 and 1, the parabola gets wider.

A parabola is a mathematical curve that is defined by a point and a line. The point is known as the focus, and the line is called the directrix. The parabola has the property that all points on it are equidistant from the focus and the directrix.

Here,

When a is negative, the parabola flips 180°.

When |a| is less than 1, the parabola opens wider.

When |a| is greater than 1, the parabola opens more narrow.

When a is between 0 and 1, the parabola gets wider, when it is greater than 1, it gets narrower, and when it is less than 0 it is reflected across the x-axis.

Therefore, when a is between 0 and 1, the parabola gets wider.

The area of the field = 19966.21 units²

Step-by-step explanation:

* Lets explain how to find area of a triangle by trigonometry rule

- In any triangle if you have the lengths of two sides and the measure

 of the including angle between these two sides, then the area of the

 triangle is A = [tex]\frac{1}{2}s_{1}s_{2}sin\alpha[/tex] , wher α is the

 including angle between them

* Lets solve the problem

∵ The field is shaped triangle

∵ The lengths of two sides of the field are 218.5 and 213.3

∴ s1 = 218.5

∴ s2 = 213.3

∵ The measure of the angle between the two sides is 58.96°

∴ α = 58.96°

- Lets find the area using the rule of trigonometry

∴ [tex]A=\frac{1}{2}(218.5)(213.3)sin(58.96)=19966.21[/tex]

∴ The area of the field = 19966.21 units²

The probability of an event and its complement add up to 1. If the probability of an event is 0.3, the probability of its complement is 0.7.

The probability of an event and its complement always add up to 1. So, if the probability of an event is 0.3, the probability of its complement can be calculated by subtracting the probability of the event from 1. In this case, the probability of the complement would be 1 - 0.3 = 0.7. Therefore, the probability of the complement is 0.7.

The correct option is C

Step-by-step explanation:

81x²+72x+16

We have to break the middle term:

If we multiply 81 by 16 we get 1296:

The same answer we get when we multiply 36 by 36:

36*36=1296

And if we add 36+36 then we get the middle term which is 72.

Answer:

The integers are -5 , -6 ⇒ answer C

Step-by-step explanation:

* Lets explain the meaning of consecutive numbers

- Consecutive numbers are numbers that follow each other in order.

-  They have a difference of 1 between every two numbers

- Consider that the smaller of two consecutive integer is n, then the

  larger one will be n + 1

* In the problem

∵ The larger of the two consecutive integers is 7 greater than twice

  the smaller

- That means the larger one is 7 plus twice the smaller

∵ The smaller one is n

∵ The larger one is n + 1

∴ n + 1 = 2(n) + 7

∴ n + 1 = 2n + 7

- Subtract n from both sides

∴ 1 = n + 7

- Subtract 7 from both sides

∴ -6 = n

∴ The smaller number is -6

∵ The greater number is n + 1

∴ The greater number = -6 + 1 = -5

* The integers are -6 , -5

Answer:

y= -5x+12

Step-by-step explanation:

slope int form ; y=mx+b

that is the only option in that form.

Answer:

the equation is y = 5x + 12

Step-by-step explanation:

The equation of line is 10x - 2y=-2

Write this equation in slope intercept form of line y = mx + b

[tex]10x-2y=-2\\\\2y=10x+2\\\\y=5x+1[/tex]

Therefore, the slope of the line is m = 5

Now, we know that parallel lines have same slope.

Hence, slope of the required line is also 5.

Thus, the equation of line is in the form y = 5x + b

Now, use the point (0,12) to find b

12= 5(0) + b

b = 12

Hence, the equation is y = 5x + 12

In the system of equations, x represents the number of tickets of Level 1 seats while y represents the number of tickets of Level 2 seats.

Given to us,

system of equations,

Equation 1, 150x + 250y = 125,000,

Equation 2,  x + y = 50,000,

Total number of seats = 50,000 seats,

Total number of sales = $125,000,

Level 1 tickets price = $150,

Level 2 tickets price = $250,

Let us assume, Number of tickets of Level 1 is [tex]\bold x[/tex], and, Number of tickets of Level 2 is [tex]\bold y[/tex],

Total sales = (Number of tickets of Level 1 x Level 1 tickets price ) + (Number of  tickets of Level 2 x Level 2 tickets price )

Answer:

10 cm

Step-by-step explanation:

If the length of a rectangle is equal to triple the width, the width of the rectangle is 10 cm if the perimeter is 80 centimeters.​

L = 3w

P = 80

Formula: a = l × w

8W = 80 cm

W = 80 / 8 = 10 cm

Therefore, the width of the rectangle is 10 centimeters.

The width of the rectangle is found to be 10 centimeters, obtained by solving the equation created based on the fact that the perimeter of a rectangle is 2(length + width) and the given data that length is thrice the width and perimeter is 80 cm.

To figure out the width of the rectangle, we first need to understand the relationship between the length and width, and how they relate to the perimeter. The length of the rectangle is triple the width. Let's define the width as 'w'. Therefore, the length would be '3w'.

The formula for the perimeter of a rectangle is 2(length + width).

Given that the perimeter is 80 centimeters, we can set up the equation 2(3w + w) = 80. Simplifying this gives 8w = 80. To find the width 'w', we divide both sides of the equation by 8, giving us w = 10 centimeters.

Therefore, the width of the rectangle is 10 centimeters.

Answer:

6x + 8 = 32

Step-by-step explanation:

Let the number be= x

So 6 times a certain number is added to 8 which gives the answer 32.

6( x ) + 8 = 32

6x + 8 = 32

Hence this is the equational form.

On further solving we get,

6x = 32 - 8

6x = 24

x = 24 / 6

x = 4....

Answer:

The required equation is 6x+8=32

Step-by-step explanation:

Consider the provided information.

6 times a certain number is added to 8, the result is 32

Let the number is represents by x.

6 times of a number can be written as: 6x

Add 8 to the above expression.

6x+8

The expression is equal to 32.

Thus, the required equation is 6x+8=32

Answer:

The radius is [tex]\frac{\sqrt{74}}{2}[/tex].

The center is (5/2 , 9/2).

Step-by-step explanation:

The radius is half the diameter.  We aren't given the length of the diameter but we are given endpoints to one of them.

So let's find the length of that diameter using the distance formula.

The distance formula is

[tex]d=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}[/tex].

I just do big x minus small x or big y minus small y.

Anyways the points are (-1,7) and (6,2).

The x distance is 6-(-1)=7.

The y distance is 7-2=5.

So we have this using the distance formula so far:

[tex]d=\sqrt{(6-(-1))^2{(7-2)^2}[/tex]

[tex]d=\sqrt{7^2+5^2}[/tex]

[tex]d=\sqrt{49+25}[/tex]

[tex]d=\sqrt{74}[/tex]

So the radius is half that much because that was the distance between the endpoints of a diameter.

So the radius is [tex]\frac{\sqrt{74}}{2}[/tex].

Now the center of a circle will lie on the midpoint of a diameter, any given diameter.

We have the endpoints of one, so we just need to use midpoint formula.

Midpoint formula says the midpoint is (average of x, average y).

Midpoint formula: [tex](\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex].

So average of x's is (-1+6)/2=5/2.

The average of y's is (7+2)/2=9/2.

So the midpoint of the diameter or the center of the circle is at (5/2 , 9/2).

x = 12, y = 10

Step-by-step explanation:

From the figure we can see that a triangle ADC, and EB is parallel to side DC.

To find the value pf x

From the given figure we get,

<ABC = <BCD  [ corresponding angles are equal]

3x + 9 = 4x - 3

4x - 3x = 9 + 3

x = 12

To find the value of y

<ABE and <EBC are linear pairs.

Therefore, <ABE + <EBC = 180

(3x + 9)  + (14y - 5) = 180

(3 * 12 + 9) + 14y - 5 = 180

45 + 14y - 5 = 180

14y = 180 -40

14y = 140

y = 140/14 = 10

y = 10

Therefore x = 12 and y = 10

Answer:

See below in bold.

Step-by-step explanation:

(g + h)(x) = 4x - 4 + x - 5

(g - h)(x) = 4x - 4 - (x - 5)  ( Note we put the x - 5 in parentheses)

= 4x - 4 - x + 5

=  3x + 1.

(g.h)(x) = (4x - 4)(x - 5)

so (g.h)(1) = (4(1) - 4)(1 - 5)

= 0 * -4

= 0.

The product of the functions will be (g·h)(x) = 4x² – 24x + 20. At x = 1, the product of the functions is zero.

A statement, principle, or policy that creates the link between two variables is known as a function.

The functions are given below.

g(x) = 4x – 4

h(x) = x – 5

Then the sum of the functions will be

(g + h)(x) = (4x – 4) + (x – 5)

(g + h)(x) = 4x – 4 + x – 5

(g + h)(x) = 5x – 9

Then the difference in the functions will be

(g – h)(x) = (4x – 4) – (x – 5)

(g – h)(x) = 4x – 4 – x + 5

(g – h)(x) = 3x + 1

Then the product of the functions will be

(g·h)(x) = (4x – 4)(x – 5)

(g·h)(x) = 4x² – 4x – 20x + 20

(g·h)(x) = 4x² – 24x + 20

At x = 1, then we have

(g·h)(x) = 4(1)² – 24(1) + 20

(g·h)(x) = 4 - 24 + 20

(g·h)(x) = 0
