In the given expression ( f(x) = 2x² + 1 ) when when ( x = 3 ), the value of f(x) is 19.

Hence D)19 Is the correct answer.

An equation is simply a mathematical formula that expresses the equality of two expressions, using the equals sign as a connection between them.

Given that;

f(x) = 2x² + 1, what is (fx) when x = 3

We substitute 3 for x in the equation

f(x) = 2(3)² + 1

f(x) = 2(9) + 1

f(x) = 18 + 1

f(x) = 19

In the given expression ( f(x) = 2x² + 1 ) when when ( x = 3 ), the value of f(x) is 19.

Hence D)19 Is the correct answer.

Step-by-step explanation:

did the test on edge

The time it will take Jack and Chris to program the app when they work together is 4.24 hours.

Rate is a ratio that compares two different quantities which have different units.

Jack program an app in 9 hours. Therefore, the rate is as follows;

1 / 9

Chris can program the same app in 8 hours. Therefore, the rate is as follows;

1 / 8

When they do it together.

1 / 9 + 1 / 8 =  8 + 9/ 72 = 17 / 72

1 / t = 17 / 72

cross multiply

72 = 17 t

t = 72 / 17

t  = 4.23529411765

t = 4.24

Therefore, the time it takes for both of them is 4.24 hours.

Hi, I am not sure if you want me to grah this or not. However, I have still provided you with the formula for this line.

Step-by-step explanation:

Perimeter of garden = 264 m

width of the garden = 56 m

length of the garden = ?

Now..

Perimeter = 2 ( l + b )

264m = 2l + 112

264 - 112 = 2l

152 = 2l

l = 152 / 2

l = 76 m

Hence the length is 76m

Step-by-step explanation:

Given:

[tex]\text{Side of }\square \ \text{= 10 units}[/tex]

Area of square:

The area of the square can be determined by using the formula "(side)²".

⇒ Area of square = (side)²

⇒                           = (10)²                                                   [Side = 10 units]

⇒                           = (10)(10)

⇒                           = 100 units²

Therefore, the area of the square is 100 units².

Perimeter of square:

The perimeter of the square can be found by using the formula "4(side)".

⇒ Perimeter of square = 4(side)

⇒                                   = 4(10)

⇒                                   = 4 × 10

⇒                                   = 40 units

Furthermore, the question says:

Which is greater?

- The number of square units (100) for the area of the square.

- The number of units (40) for the perimeter

Conclusion: Since 100 is greater than 40, the number of square units for the area of the square is greater than the number of units for the perimeter.

Answer: The second option, 1/3, 0.33, 33%

Step-by-step explanation:

    We will put the number of wanted outcomes over the number of total outcomes. 1 and 6 is two wanted outcomes.

2 / 6 = 1/3

     Now, 1/3 is equal to 0.33. A decimal multiplied by 100 is a percent, so it is also equal to 33%. Your answer is:

Step-by-step explanation:

-11x -44 + 10 x =27

-x = 71

x = - 71

Answer:

-71

Step-by-step explanation:

You can first distribute the numbers in the parenthesis.

-11x-44 (-11*x-11*4)

-11x-44+10x=27

You can now combine like terms.

-11x+10x=-1x

Answer:

$460

Step-by-step explanation:

If the 128.80 is the price of the desk after a 72% discount, it means that 128.80 is 100-72=28% of the original price.

From here, we can divide 128.80 by 28 to find what 1% of the price is then multiply the value by 100 to find 100%, or the original price.

128.80/28 = 4.6

4.6 x 100 = 460

Original price = $460

You look at the total angle and subtract it by the angle that is given in the question since the two angles should add up to the whole angle of both. You should look at the number that is outside the angles and subtract it by the angle number inside then you will get the missing angles. The last one it is showing a 90 degree angle which is formed so you subtract 63 from 90.

The speed to his sister house is 50mph.

The speed of an object is the magnitude of the rate of change of its position with time or the magnitude of the change of its position per unit of time; it is thus a scalar quantity.

Here, let the speed of his sisters house be x mph.

then, 3x = 2.5(x+10)

         3x = 2.5x + 25

        3x - 2.5x = 25

        0.5x = 25

          x = 25 / 0.5

Using the triangle inequality theorem, the set of lengths that meet all the requirement is: 3, 4, 5, 7.

The triangle inequality theorem states that the sum of any of the two sides of a triangle must be equal or greater than the third side, i.e. if a, b, and c are sides of a triangle, then:

If we have the following set of numbers, 3, 4, 5, 7.

Set 3, 4, 5 will give us:

This means 3, 4, 5 will form a triangle.

Set 4, 5, 7 will give us:

This means 4, 5, 7 will form a triangle.

Answer: 8y

Step-by-step explanation:

The values needed to find the length AB will be;

⇒ AB = √(3x)² + (- 8y)²

Line segment is a part of the line which have two endpoints and bounded by two distinct end points and contain every point on the line which is between its endpoint.

Given that;

The coordinate are,

⇒ A = (- 5x, 4y)

⇒ B = (- 2x, - 4y)

Now,

Since, We know that;

The distance between the points (x₁ , y₁) and (x₂, y₂) is,

⇒ d = √ (x₂ - x₁)² + (y₂ - y₁)²

So, The distance between the points (- 5x, 4y) and (- 2x, - 4y) is,

⇒ d = √ (- 2x - (- 5x))² + (- 4y - 4y)²

⇒ d = √(3x)² + (- 8y)²

Thus, The values needed to find the length AB is find as;

Answer:

124 amigo dame corona no e tenido

Answer:

Step-by-step explanation:

The x-intercepts are the points with y- coordinate of 0

a) x-intercepts are

b) midpoint of x-intercepts is

c) The extheme value has x- coordinate of - 2.5 and y- coordinate

d) f(- 2.5) = - 30.25

Answer:

[tex]\sf a) \quad x = -8 \:\:and \:\:x = 3[/tex]

[tex]\sf b) \quad \left(-\dfrac{5}{2},0\right)[/tex]

[tex]\sf c) \quad \left(-\dfrac{5}{2},-\dfrac{121}{4}\right)[/tex]

[tex]\sf d) \quad f(x)=\left(x+\dfrac{5}{2}\right)^2-\dfrac{121}{4}[/tex]

Step-by-step explanation:

Part (a)

The x-intercepts are the x-values when the curve crosses the x-axis, so when the function is equal to zero:

[tex]\implies f(x)=0[/tex]

[tex]\implies (x-3)(x+8)=0[/tex]

Therefore:

[tex](x-3)=0 \implies x=3[/tex]

[tex](x+8)=0 \implies x=-8[/tex]

Therefore, the x-intercepts are x = -8 and x = 3

Part (b)

[tex]\textsf{Midpoint}=\left(\dfrac{x_2+x_1}{2},\dfrac{y_2+y_1}{2}\right)\quad \textsf{where}\:(x_1,y_1)\:\textsf{and}\:(x_2,y_2)\:\textsf{are the endpoints}}\right)[/tex]

[tex]\sf \implies Midpoint=\left(\dfrac{-8+3}{2},\dfrac{0+0}{2}\right)=\left(-\dfrac{5}{2},0\right)[/tex]

Therefore, the midpoint of the x-intercepts is (-5/2, 0)

Part (c)

The extreme value is the vertex.  The vertex is:

The x-coordinate of the vertex is the x-value of the midpoint of the x-intercepts.  Therefore, the x-value of the extreme value is x = -5/2.

To find the y-coordinate, substitute this into the given equation:

[tex]\implies \sf y=\left(-\dfrac{5}{2}-3\right)\left(-\dfrac{5}{2}+8\right)=-\dfrac{121}{4}[/tex]

Therefore, the extreme value is:

[tex]\sf \left(-\dfrac{5}{2},-\dfrac{121}{4}\right)[/tex]

Part (d)

The function in vertex form is:

[tex]\sf f(x)=\left(x+\dfrac{5}{2}\right)^2-\dfrac{121}{4}[/tex]

[tex]\begin{aligned}\implies \sf f\left(-\dfrac{5}{2}\right)& = \sf \left(-\dfrac{5}{2}+\dfrac{5}{2}\right)^2-\dfrac{121}{4}\\\\ & = \sf 0 -\dfrac{121}{4}\\\\ & = \sf -\dfrac{121}{4} \end{aligned}[/tex]
