Answer:

f(x)=(x+2)^2+37

Step-by-step explanation:

Got it right on Khan :)

The quadratic function f(x) = x² + 4x + 41 is converted into square form is f(x) = (x + 2)² + 37.

The quadratic equation is given as ax² + bx + c = 0. Then the degree of the equation will be 2.

The quadratic function is given below.

f(x) = x² + 4x + 41.

The quadratic function is converted into square form by adding and subtracting the square of the half of the coefficient of x.

f(x) = x² + 4x + 41

Transform into square form. Then the quadratic function will be

f(x) = (x² + 4x + 4) + 41 – 4

f(x) = (x + 2)² + 37

The quadratic function f(x) = x² + 4x + 41 is converted into square form is f(x) = (x + 2)² + 37.

Answer:

x=4

Step-by-step explanation:

we know that the 3x-3 and x+5 are congruent to each other so we can do 3x-3=x+5. After this we can add 3 to each side to get 3x=x+8 then subtract a x from each side to get 2x=8. Then we divide by 2 to get x=4

Answer:

21%, 0.21, 11/50, 2/9

Step-by-step explanation:

To arrange from least to greatest, we need to first express all as percemtage;

2/9 = 2/9 * 100 = 200/9 = 22.2%

21% = 0.21

0.21 = 0.21 * 100 = 21%

11/50 = 11/50 * 100 = 11*12 = 22%

Hence the values from least to greatest is 21%, 0.21, 11/50, 2/9

Given:

The function is

[tex]f(x+2)=2x+3[/tex]

To find:

The value f'(4).

Solution:

We have,

[tex]f(x+2)=2x+3[/tex]

Putting [tex]x+2=t[/tex] and [tex]x=t-2[/tex] we get

[tex]f(t)=2(t-2)+3[/tex]

[tex]f(t)=2t-4+3[/tex]

[tex]f(t)=2t-1[/tex]

Differentiate with respect to t.

[tex]f'(t)=2(1)-0[/tex]

[tex]f'(t)=2[/tex]

At [tex]t=4[/tex], we get

[tex]f'(4)=2[/tex]

Therefore, the value of f'(4) is 2.

Answer:

499/999

Step-by-step explanation:

The decimal number written is:

0.499...

Such that these 3 decimals are repeated as:

0.499499499...

Let's define this number as k

k = 0.499...

Let's multiply this number by 1000 (the same number of zeros as important decimals after the decimal point)

we get:

1000*k = (1000)*(0.499...) = 499.499...

Now we can subtract the original number k, so we get:

1000*k - k = 499.499... - 0.499...

In this way, we remove the part after the decimal point:

1000*k - k = 499.499... - 0.499...

(1000 - 1)*k = 499

999*k = 499

Now we can divide both sides by 999

(999*k)/999 = 499/999

k = 499/999

The fraction notation of our number is 499/999 (and this is the simplest form)

Answer:

            [tex]\bold{m_2=\dfrac12}[/tex]

            [tex]\bold{m_3=-1\dfrac12}[/tex]

Step-by-step explanation:

The slope of the line passing through two given points:  [tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

(0, 5)   ⇒   x₁ = 0,  y₁ = 5

(8, 2)   ⇒     x₂ = 8,  y₂ = 2

So, the slope:

                     [tex]m_1=\dfrac{2-5}{8-0}=\dfrac{-3}{8}=-\dfrac38[/tex]

(2, -1)   ⇒   x₁ = 2,  y₁ = -1

(6, 1)   ⇒     x₂ = 6,  y₂ = 1

The slope:

                     [tex]m_2=\dfrac{1-(-1)}{6-2}=\dfrac{2}{4}=\dfrac12[/tex]

(-3, -2)   ⇒   x₁ = -3,  y₁ = -2

(-1, -5)   ⇒     x₂ = -1,  y₂ = -5

The slope:

                     [tex]m_3=\dfrac{-5-(-2)}{-1-(-3)}=\dfrac{-3}{2}=-\dfrac32=-1\frac12[/tex]

Answer:

1) m<RAS = 126

2) x = 144

Step-by-step explanation:

1)

10x + 36 + 6x = 180

16x + 36 = 180

16x = 144

x = 9

<RAS:

10x + 36

10(9) + 36 = 126

2)

54 + 90 + y = 180

y + 144 = 180

y = 36

x + y = 180

x + 36 = 180

x = 144

Answer:

AD = 230

Step-by-step explanation:

AD = 30x - 10

MN = 31x + 1

BC = 30x + 28

To find the length of AD, we need to generate an equation that will enable us to find the value of x.

Thus,

MN = ½(AD + BC) => Trapezoid Midsegment Theorem

Plug in the values

31x + 1 = ½(30x - 10 + 30x + 28)

(31x + 1) × 2 = 30x - 10 + 30x + 28

62x + 2 = 30x - 10 + 30x + 28

Add like terms

62x + 2 = 60x + 18

62x - 60x = -2 + 18

2x = 16

x = 16/2

x = 8

✅AD = 30x - 10

Plug in the value of x

AD = 30(8) - 10 = 230
