Multiplying the decimal number by 1000

Step-by-step explanation:

consider the number 12.2345.

For you to move the decimal point three places to the right, you have to multiply the number with 10³=1000

12.2345×1000= 12234.5

The decimal has moved from three places as it has skipped three places values to the right.

The choice which is the same as moving the decimal point 3 places to the right in a decimal number is; Multiplying the number by 1000.

According to the task content;

Since, a decimal point movement one space to the right indicates a multiplication by 10, hence, it follows that the required multiplication is 1000.

Answer:

Opt B. y=5-3x

Step-by-step explanation:

We need to write the given equation in slope-intercept form, so we can obtain the slope and the 'y' axis intercept point.

To do this, we need to isolate 'y' variable with a possitive sign, hence we perform the following operation:

Subtraction of -5 in both sides of equality sign.

-y=3x-5

Lets multiply by -1 the equation from above:

y= 5-3x.

From the above we can find the slope, is the coefficient of x. in this case -3

The options are given.

Let us take the options one by one:

Now, substitute (0,0) in the inequalities:

0 ≥  2 and 0 ≤  3

This is not true.

Now, substitute (0,0) in the inequalities:

0 ≥ - 2 and 0 ≤ - 3

This is not true.

Now, substitute (0,0) in the inequalities:

0 ≥ - 2 and 0 ≤ 3

This is true.

Now, substitute (0,0) in the inequalities:

0 ≥ - 2 and 0 ≤ - 3

This is not true.

Maximum value of the function is 4.

Step-by-step explanation:

Given function of simple harmonic motion is [tex]d=4\sin\left(\frac{\pi}{8}t\right)[/tex].

Now we need to find about what is the maximum value of [tex]d=4\sin\left(\frac{\pi}{8}t\right)[/tex].

We know that value of sine function varies from -1 to 1.

that means for any value of t, maximum value of sine function is 1.

[tex]\sin\left(\frac{\pi}{8}t\right) \leq 1[/tex]

[tex]4 \sin\left(\frac{\pi}{8}t\right) \leq 4[/tex]

[tex]d \leq 4[/tex]

Hence maximum value of the function is 4.

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.

Step-by-step explanation:

11/7 As A Mixed Number Would Be 1 And 4/7

What we are given:

r( x ) = x - 3

s( x ) = 4x²

We have to find:

( s + r )( x ) = ( x - 3 + 4x² )

→ 4x² + x - 3

( s - r )( x ) = ( x - 3 - 4x² )

→ -4x² + x - 3

For the last function, I am confused whether it is a multiplication or composite function, so I am going to do both.

Multiplication:

( x - 3 ( 4x² ))( 2 )

( 4x³ - 12x² )( 2 )

4(2)³ - 12(2)²

4(8) - 12(4)

32 - 48

→ -4

Composite function:

r(s(x))(2) = r(4x²) = 4x² - 3  = 4(2)² - 3 = 4(4) - 3 = 16 - 3

→13

Final answer:

The expressions for (s+r)(x) is 4x^2 + x - 3 and (s-r)(x) is 4x^2 - x + 3. The value of (s.r)(2) is 16.

Explanation:

To find the expression for (s+r)(x), we need to add the functions s(x) and r(x). Adding the two functions, we get (s+r)(x) = 4x^2 + (x-3). Simplifying this expression, (s+r)(x) = 4x^2 + x - 3.

To find the expression for (s-r)(x), we need to subtract the function r(x) from s(x). Subtracting the two functions, we get (s-r)(x) = 4x^2 - (x-3). Simplifying this expression, (s-r)(x) = 4x^2 - x + 3.

To evaluate (s.r)(2), we need to substitute 2 for x in the expression s(x) * r(x). Substituting 2 for x in the expression 4x^2, we get (s.r)(2) = 4(2)^2 = 16.

Answer:

A  = $2200(7.612) = $16,747.28

Step-by-step explanation:

You don't say whether this is simple interest or compound interest.  I will assume you meant compound interest, for which the appropriate formula is

A = P(1 + r)^t, where P is the principal amount, r is the interest rate as a decimal fraction, and t is the time in years.  Then:

A = $2200(1 + 0.0725)^29, or

A = $2200(1.0725)^29, or

A  = $2200(7.612) = $16,747.28

The amount in the account after 29 years will be approximately $8484.64.

To calculate the amount of money that will be in the account after 29 years, we can use the formula for compound interest: A = P(1 + r/n)^(nt), where A is the final amount, P is the principal amount ($2200 in this case), r is the annual interest rate (7.25% or 0.0725 as a decimal), n is the number of times interest is compounded per year (in this case, it's compounded annually, so n is 1), and t is the number of years (29 in this case). Plugging in the values, we get:

A = 2200(1 + 0.0725/1)^(1*29)

A = 2200(1.0725)^29

A ≈ $8484.64

Answer:

I'm not sure if this is the answer answer but this what the graph is a parabola

The function represented by the graph is y = 1/4(x - 2)^2 + 1

What function does this graph represent?

From the question, we have the following parameters that can be used in our computation:

The graph

The graph is the graph of a quadratic function

By definition:

A quadratic function is represented as

y = a(x - h)^2 + k

Where

Vertex = (h, k)

From the graph, we have

Vertex = (2, 1)

So, we have

y = a(x - 2)^2 + 1

Using the point (0, 2) on the graph, we have

a(0 - 2)^2 + 1 = 2

4a + 1 = 2

4a = 1

a = 1/4

So, we have

y = 1/4(x - 2)^2 + 1

Hence, the function this graph represent is y = 1/4(x - 2)^2 + 1

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.

Answer:

(- 1, 2)

Step-by-step explanation:

Given a quadratic in standard form y = ax² + bx + c : a ≠ 0

Then the x- coordinate of the vertex is

[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]

f(x) = x² + 2x + 3 ← is in standard form

with a = 1 and b = 2, hence

[tex]x_{vertex}[/tex] = - [tex]\frac{2}{2}[/tex] = - 1

Substitute x = - 1 into f(x) for corresponding value of y

f(- 1) = (- 1)² + 2(- 1) + 3 = 1 - 2 + 3 = 2

vertex = (- 1, 2 )

QUESTION 1

[tex] \boxed {f(x) = 2x + 6 \to \: g(x) = \frac{1}{2}x - 3 } [/tex]

[tex]g(f(x)) = x - 6+ 6 [/tex]

[tex]g(f(x)) = x[/tex]

QUESTION 2

[tex]\boxed {f(x) =3 - 2x \to \: g(x) = - \frac{1}{2}(x - 3)} [/tex]

[tex]g(f(x)) = - \frac{1}{2} (- 2x )[/tex]

[tex]g(f(x)) =x[/tex]

QUESTION 3

[tex]\boxed {f(x) = \sqrt[3]{3x}+ 2 \to \: g(x) = \frac{ {(x - 3)}^{3} }{3} } [/tex]

The reason is that:

[tex]f(g(x)) = \sqrt[3]{ \frac{3 {(x - 2)}^{3} }{3} } + 2[/tex]

[tex]f(g(x)) = x-2 + 2[/tex]

[tex]f(g(x))=x[/tex]

QUESTION 4
