To change the graph of f(x) = [tex]x^2[/tex] into g(x) = 4[tex]x^2[/tex] + 24x + 30, the transformations include a vertical stretch by a factor of 4 and a shift to the left by 3 units and up by 6 units. Completing the square helps identify these shifts.

To transform the graph of f(x) = [tex]x^2[/tex] into the graph of g(x) = 4[tex]x^2[/tex] + 24x + 30, we can analyze the changes applied. First, the coefficient of x2 in g(x) is 4, which means the original parabola is vertically stretched by a factor of 4. Second, the term 24x indicates a horizontal transformation, specifically a shift, which is revealed when we complete the square.

To complete the square for the quadratic part of g(x), we rewrite the equation as 4([tex]x^2[/tex] + 6x) + 30 and add and subtract the square of half the coefficient of x inside the parentheses, giving us 4((x + 3)2 - 9) + 30. This simplifies to 4(x + 3)2 + 6, indicating that the graph of f(x) was also shifted to the left by 3 units and up by 6 units.

Let's do the same thing to evaluate g(-5):

-5Answer:

Step-by-step explanation:

Never heard of "synthetic substitution."  I think you meant "synthetic division," which is a great method of evaluating polynomials for given input values.

g(x) = x^5 – 8x^3 – 2x + 7 is missing two terms.

With all terms showing, it would read:

g(x) = x^5 – 0x^4 + 8x^3 – 0x^2 - 2x + 7.  The coefficients are {1, 0, 8, 0, -2, 7}.

Let's evaluate g(3).  Use 3 as divisor in synth. div.:

ANSWER

x=100,y=10

EXPLANATION

The given logarithmic equations are;

[tex] log_{10}( {x}^{2} {y}^{3} ) = 7[/tex]

This implies that,

[tex] {x}^{2} {y}^{3} = {10}^{7} ...(1)[/tex]

and

[tex] log_{10}( \frac{x}{y} ) = 1[/tex]

This implies that,

[tex] \frac{x}{y} = {10}^{1} [/tex]

[tex]x = 10y...(2)[/tex]

Put equation (2) into equation (1)

[tex]{(10y)}^{2} {y}^{3} = {10}^{7}[/tex]

[tex]10 ^{2} y^{2} {y}^{3} = {10}^{7}[/tex]

[tex]{y}^{5} = {10}^{5}[/tex]

Hence y=10.

This implies

[tex]x = 10(10) = 100[/tex]

Answer:

3. Since the range of the original function is limited to y> 6, the domain of the inverse function is x ≥ 6.

Step-by-step explanation:

The domain of a function is the range of its inverse, and vice versa. The only answer choice that expresses this relationship is choice 3.

__

Comment on the answer choice:

The slope of the function is undefined at x=4, so restricting the function domain to the portion with positive slope means the domain restriction of the function is x > 4. That also means the range restriction of the function is y > 6. The domain restriction of the inverse function is the same: x > 6, not x ≥ 6. The answer choice has an error.

The domain of the original function with the positive slope is restricted to x > 4, and the range of f(x) is y ≥ 6. Therefore, the domain of the inverse function is x ≥ 6.

The function given is f(x) = |x – 4| + 6. When restricting the domain to the portion of the graph with a positive slope, the function increases. In the absolute value function, the slope changes at the vertex, which here is when x = 4. For x > 4, the slope is +1 because the graph of the function is increasing. So, considering the domain x > 4 makes the graph of the function only represent the portion with a positive slope.

The range of the original function with the restricted domain is f(x) ≥ 6, because the lowest value of |x – 4| is 0 when x ≥ 4, which results in f(x) = 0 + 6 = 6 when x = 4. Consequently, the corresponding range of the inverse function must be the domain of the original function, and thus, the domain of the inverse function must be x ≥ 6.

Answer:

x = - [tex]\frac{1}{4}[/tex], x = 2

Step-by-step explanation:

Given

8x² - 14x - 4 = 0 ( divide through by 2 to simplify )

4x² - 7x - 2 = 0

To factorise the quadratic

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term

product = 4 × - 2 = - 8 and sum = - 7

The factors are - 8 and + 1

Use these factors to split the x- term

4x² - 8x + x - 2 = 0 ( factor the first/second and third/fourth terms )

4x(x - 2) + 1(x - 2) = 0 ← factor out (x - 2) from each term

(x - 2)(4x + 1) = 0

Equate each factor to zero and solve for x

4x + 1 = 0 ⇒ 4x = - 1 ⇒ x = - [tex]\frac{1}{4}[/tex]

x - 2 = 0 ⇒ x = 2

Answer:

The principal of the loan is $350000

$26844 is not half 54886 so the statement is not true

Step-by-step explanation:

* Lets use the given rule to solve the question

- The total loan amount to be paid = p (1 + r)^t , where

# t is time in years,

# r is interest rate as a decimal

# p is the principal of the loan

- To find t divide the number of months by 12

∵ t = 30/12 = 2.5 years

∵ r = 6/100 = 0.06 ⇒ the interest rate in decimal

∵ The total loan amount to be paid = $404,886

∴ 404,886 = p (1 + 0.06)^2.5

∴ 404,886 = p (1.06)^2.5 ⇒ divide both sides by (1.06)^2.5

∴ p = 404,886 ÷ [(1.06)^2.5] ≅ $350,000

* The principal of the loan is $350,000

- To check the statement of the manager lets find the difference

  between the total loan amount and the principal

∵ The principal of the loan is $350,000

∵ the total loan amount to be paid is $404,886

∴ The difference = 404,886 - 350,000 = $54886

- Lets find the total loan amount to be paid when the interest rate

 was cut in half

∵ The total loan amount to be paid = p (1 + r)^t

∵ t = 30/12 = 2.5 years

∵ The half of 6% is 3%

∴ r = 3/100 = 0.03 ⇒ the interest rate in decimal

∵ p = $350,000

∴ The total loan amount to be paid = 350,000 (1 + 0.03)^2.5

∴ The total loan amount to be paid = 350,000 (1.03)^2.5

∴ The total loan amount to be paid = $376,844

- Lets find the difference between the total amount to be paid and

 the principal

∴ The difference = 376,844  - 350,000 = $26844

∵ $26844 is not half 54886

* The statement is not true

21.6 x 5.9 x 0.5 = 63.72

The area of the triangle is 63.72 ft²

Answer:

63.72 ft^2

Step-by-step explanation:

The base and the height of the triangle are given:  21.6 ft and 5.9 ft.

Apply the area-of-a-triangle formula:

A = (1/2)(base)(height)

Here, the area is

A = (1/2)(21.6 ft)(5.9 ft) = 63.72 ft^2

Answer:

x = π/2 or

x = π/2 + 2πn (for any value of n)

Step-by-step explanation:

We need to find the numerical value of the trigonometric function sinx+1/sinx=1+cscx

Subtract 1+cscx on both sides

sinx + 1/sinx -(1+csc x) = 1+cscx - (1+cscx)

sinx + 1/sinx -1 -csc x = 0

Taking LCM i.e, sinx and solving

(sinx)(sinx) + 1 - sinx -cscx(sinx) / sinx = 0

Multiplying sinx on both sides

sin^2 x + 1 -sinx - cscx(sinx) =0

as we know, cscx = 1/ sinx

sin^2 x + 1 -sinx - (1/sinx)(sinx) = 0

Solving,

sin^2 x + 1 -sinx - 1 = 0

sin^2 x - sin x =0

Let u = sinx

Putting it in above equation

u^2 - u =0

Solving the equation:

u= 1 , u= 0

Putting back the value of u

sin(x) = 1 and sin(x) = 0

x = sin ⁻¹ (1) and x = sin ⁻¹ (1) =0

x = 90° or π/2 and x = 0 (undefined for the question)

So, x = π/2 or

x = π/2 + 2πn (for any value of n)

x% of y equals to 0.01*x*y

Just put the numbers in the formula

33% of 507 = 167.31

48% of 375 = 180

76% of 285 = 216.6

60% of 398 = 238.8

89% of 150 = 133.5

26% of 430 = 111.8

81% of 216 = 174.96

5% of 584 = 29.2

18% of 725 = 130.5

2% of 115 = 2.3

90% of 152 = 136.8

12% of 649 = 77.88

55% of 216 = 118.8

43% of 108 = 46.44

97% of 235 = 227.95

Answer:

C

Step-by-step explanation:

Since the triangle is right use Pythagoras' identity to solve for x

The square on the hypotenuse is equal to the sum of the squares on the other two sides.

Note the 2 legs are equal, that is both x, hence

x² + x² = 16²

2x² = 256 ( divide both sides by 2 )

x² = 128 ( take the square root of both sides )

x = [tex]\sqrt{128}[/tex] = [tex]\sqrt{64(2)}[/tex] = [tex]\sqrt{64}[/tex] × [tex]\sqrt{2}[/tex] = 8[tex]\sqrt{2}[/tex]

Answer:

all real numbers greater than or equal to 3

Step-by-step explanation:

There's some ambiguity in your "3/x+2-sqrt x-3."  I will assume that you meant:

   3

---------- - sqrt(x - 3).       Using parentheses often changes everything.

 x + 2  

Here we see that x cannot = -2, because x + 2 would be zero then.  And x must be greater than or equal to 3, so that the input to the sqrt function will be 0 or greater.  The domain for f(x) is all real numbers greater than or equal to 3.  The prohibition against x = -2 has no bearing on the overall domain of this function.

Answer:

The domain for f(x) is all real numbers GREATER than or equal to 3

The diameter of the largest pen you could build is [tex]\frac{100}{\pi }[/tex] or [tex]31.8309[/tex] ft

Step-by-step explanation:

As the equation for the circumference of a circle is

[tex]C=d\pi[/tex]

We can plug in the known value for C, which is 100 and solve for d

[tex]100=d\pi[/tex]

[tex]d=\frac{100}{\pi }[/tex]

ANSWER

The diameter of the largest pen you can build is 31.8 feet to the nearest tenth.

EXPLANATION

You have 100 feet of fencing to build a circular sheet pen.

The largest diameter you can get is when you use all the 100 feet of fencing to build the sheet pen.

The circumference of the circular sheet pen must then be 100 feet.

Then using the formula for circumference, we have:

C=πd

100=πd

[tex]d = \frac{100}{\pi} [/tex]

d=31.83 ft.

The safe dose for the child is:   [tex]640\ \frac{mg}{day}[/tex]

Step-by-step explanation:

We know that the conversion factor is 40 mg/kg/day

The child weighs 16 kg. This means that 40 mg per day corresponds to each kilogram of the child.

So to know how many milligrams per day correspond per day we must multiply 16 kg by the conversion factor

[tex]16\ kg * 40\ \frac{\frac{mg}{kg}}{day} = 640\ \frac{mg}{day}[/tex]

Answer:

The safest dose would be 640 mg per day.

The answer is:

The second option,

b.) [tex]C(x)=40.60x+201[/tex]

We are given the functions E(x) and K(x), since they both are function of the same variable, we need to add them in order to find the correct option.

From the statement we know the functions:

[tex]E(x)=22.75x+74[/tex]

and

[tex]K(x)=17.85x+127[/tex]

So, adding the functions we have:

[tex]C(x)=E(x)+F(x)[/tex]

[tex]C(x)=(22.75x+74)+(17.85x+127)[/tex]

[tex]C(x)=22.75x+17.85x+74+127[/tex]

[tex]C(x)=40.60x+201[/tex]

Hence, the answer is the second option,

Answer: I would just say add a line to the Equal sign so the equation would read

5+5+5≠550, since this way it would say that 5+5+5 ISNT equal to 550 which is technically true, but that might be wrong.

Answer:

Step-by-step explanation:

Let's say R is roses, L is lilies, and O is orchids.

R = 2L

O = R + 5

R + L + O = 45

Let's substitute the second equation into the third:

R + L + (R + 5) = 45

2R + L = 40

Now substitute the first equation:

2(2L) + L = 40

4L + L = 40

5L = 40

L = 8

Therefore:

R = 2L = 16

O = R + 5 = 21

There are 16 roses, 8 lilies, and 21 orchids.
